Medals are once again on the line for another action-packed day of the 2020 Tokyo Games. The Aussie Boomers, Kookaburras and Stingers enter do-or-die clashes, while today marks the start of the Sport Climbing event.
Meanwhile, it's another massive day of track and field as the highly anticipated men's 1500m kicks off, as well as the women's javelin throw. Brooke Stratton (long jump), Jake Lilley (sailing), Tyson Bull (artistic gymnastics) and Kurtis Marschall (pole vault) are all looking to add to Australia's gold medal tally.
Read on for rolling coverage of Australia's efforts at the Olympics:
Boomers book semifinal with Team USA
They got off to a sluggish start, but Australia then steadied before running away with their Olympic quarterfinal against Argentina 97-59.
The 38-point victory means Australia now face the United States in the semifinals after the Americans defeated Spain earlier on Tuesday.
Kookaburras beat Germany to make final
The Kookaburras will play in the men's hockey final at the Olympic Games for the first time since 2004, having defeated Germany 3-1 in the semis.
World No.1 Australia will battle Belgium for the gold medal in Tokyo on Thursday evening.
Stingers stun by quarter-final loss
A scrappy 9-8 loss to Russia has ended Australia's bid for their first medal in water polo since the London Olympics.
The Stingers rallied after trailing 8-4 and 9-6 in the second half of Tuesday night's Tokyo Olympics women's quarter-final.
Bronte Halligan's second goal, coming with 16 seconds remaining in the match, gave her side hope.
But there was no miraculous equaliser, with several Australians reduced to tears after a gutting result that came five years after losing a quarter-final shootout at Rio de Janeiro.
Australia coach Predrag Mihailovic was given a red card late in the final quarter of a physical clash in which momentum shifted frequently as both sides were repeatedly penalised with exclusions and fouls.
The Stingers will play two classification matches to determine their final ranking, between fourth and eighth, while Russia advances to Thursday's semi-final against the United States.
Bull takes fifth in horizontal bar
Australian Tyson Bull has finished fifth in the horizontal bar event after making history in artistics gymnastics.
He was the first Australian to make an Olympic men's artistic gymnastics final.
In his Olympic debut, the 28-year-old Victorian fell off the bar during his routine and scored 12.466.
It was well short of his qualifying score of 14.433, Bull's personal best at an international event.
He had plenty of company, with several other competitors in the eight-man final also suffering falls.
But Japanese teenager Daiki Hashimoto was not one of them.
After qualifying first, Hashimoto was outstanding again in the final and won gold with 15.066.
Croatian Tin Srbic scored 14.900 for silver and Russian Nikita Nagornyy (14.533) won bronze.
Bull held third spot before Srbic and then Hashimoto stamped their authority on the final.
Bull is the first Australian to compete in men's artistic gymnastics at the Olympics since Josh Jefferis at the London Games.
Marschall last in Olympic pole vault final
Australian Kurtis Marschall insists a difficult and disjointed buildup had nothing to do with the hugely disappointing way he bowed out of the Olympic pole vault final.
Marschall, who was considered a legitimate medal chance at the Tokyo Games, did not register a clearance after dislodging the bar with all three attempts at his opening height of 5.55m.
The 24-year-old Commonwealth Games champion has a personal best of 5.87m and cleared 5.75m at the first time of asking in the qualifying round just three days ago.
But he was unable to get going at all on Tuesday evening with the medals up for grabs.
"I wasn't able to hit my cues tonight," he told the Seven Network.
"I though my prep was perfect, all of this other stuff that happened in the background was like nothing.
"I was out there feeling awesome, I couldn't wait to get amongst it with the boys, but sometimes that's just sport.
"There are so many different elements in pole vault that you have to nail and execute perfectly.
"The guys that you are seeing right now, all credit to them because they've obviously worked their arses off to get where they are and they make it look easy.
"I made it look hard tonight."
Garside guaranteed boxing medal
Harry Garside is guaranteed Australia's first Olympic boxing medal in more than 30 years, and possibly the country's first gold, after the lightweight beat Kazakhstan's Zakir Safiullin in a tense split decision quarter-final at Tokyo.
The qualified plumber will add at least a Games bronze to his 2018 Commonwealth gold, given both semi-final losers in boxing are awarded third place.
Garside won 3-2, with each round split 3-2 between the five judges and a frenzied final round going his way to the shock of the plucky Kazakhstan boxer.
Australia hasn't won an Olympic boxing medal since Grahame "Spike" Cheney's light welterweight silver at Seoul 1988.
Australian medal chance, featherweight Skye Nicolson, was stopped in the Tokyo quarter-finals in devastating fashion last week.
The 24-year-old Garside - Australia's last live boxing hope in Tokyo - will have to beat world champion Andy Cruz on Friday.
Cruz impressively won in the earlier bout over Brazil's Wanderson de Oliveira.
Australia to ride for men's pursuit bronze
Australia will ride off for the men's team pursuit bronze medal after another night of high drama in Olympic track cycling.
It took well over an hour for race judges to determine Wednesday's gold and bronze medal rides, after Danish rider Frederik Madsen collided with Great Britain's Charlie Tanfield near the end of the fourth and final heat.
That came the day after Australian Alex Porter had face-planted into the track at 65km/h when the handlebars inexplicably snapped off his bike in qualifying.
The Danes were winning easily and on target for the gold medal ride-off, but Madsen had his head down and appeared not to realise Tanfield had dropped well off the back of the British paceline.
Tanfield had been brought in as a late replacement for three-time team pursuit gold medallist Ed Clancy, who announced his retirement after a back injury had flared up in qualifying.
Neither Denmark nor Great Britain recorded a finishing time, sparking chaos and confusion at the Izu Velodrome.
Eventually, Denmark was awarded the win and will ride off for gold against Italy, who broke the world record in their heat win over New Zealand.
Australia will go up against New Zealand for the bronze medal and Great Britain, winners of the last three Olympic gold in the event, will ride off for seventh place.
New Zealand will start favourites after posting a quicker time in their heat.
Italy broke Denmark's world record with three minutes 42.307 seconds and the New Zealanders also went under the old mark with 3:42.397.
Australia, who eventually qualified fifth-fastest on Monday when they were given a re-start, brought in Luke Plapp to replace Porter as he nurses friction burns on his face.
Plapp, Leigh Howard, Sam Welsford and Kelland O'Brien clocked 3:44.902 in their easy win over Switzerland - the fastest Australia has ridden in the event.
Also on Tuesday night, Australia was denied bronze in the men's team sprint after qualifying third-fastest and also posting the third-fastest time in the opening round.
Matthew Glaetzer, the third rider in their combination behind Matthew Richardson and Nathan Hart, struggled at the end of the bronze medal ride against France.
Australia posted 44.013 as France won in 42.331, while favourites The Netherlands easily beat Great Britain for the gold medal in a Games record time of 44.589.
France also beat Australia for the bronze in Rio.
"It's a tough one, for sure, we came here with the hopes of winning a medal and some days you have days like this," Richardson said.
"Everyone knows how hard it is for man three."
Australia finished fifth in the women's team pursuit, again their same result at the Rio Games.
They improved markedly on their second-last qualifying time on Monday, but it was only enough for fifth-fastest in the heats and that put them out of the bronze medal ride.
Annette Edmondson, Georgie Baker, Maeve Plouffe and Alex Manly narrowly beat Italy in the ride-off for fifth place, their same result as the Rio Olympics.
Germany broke the world record again - the fourth time it has fallen in the last two days - beating Great Britain for the gold medal.
The Germans reduced the world mark to 4:04.242 to break the British stranglehold on the event.
The United States, coached by Australian Gary Sutton, beat Canada for the bronze medal.
Aussie sailors unbeatable in 470 class
Mat Belcher and Will Ryan are on the cusp of sailing gold after building an unassailable lead in the men's 470 class in Tokyo.
Following in the wake of Matt Wearn, who did the same in the Laser class, the duo only have to finish or avoid disqualification in Wednesday's medal race to collect Australia's second sailing gold.
It's Belcher's second gold medal after winning the event in London with Malcolm Page, while he and Ryan won silver in Rio.
The Australians held a 19-point buffer atop the 470 leaderboard heading into race nine, and a second place off Enoshima Harbour pushed it out to 22.
In a nerve-wracking 10th race the Swedish team of Anton Dahlberg and Fredrik Bergstrom took out the race, with Belcher and Ryan crossing in eighth spot to build a 20-point lead.
That means they can't be overtaken despite double points being on offer in the medal race.
NZ kayak star does it again
New Zealand great Lisa Carrington has captured her fourth Olympic canoe sprint gold medal, with Australia's Alyssa Bull and Alyce Wood finishing fifth in a tight women's K2 500 metres final.
Carrington's victory with partner Caitlin Regal came after she also clinched gold earlier on Tuesday in the K1 200 metres, which she has now won at three successive Games.
In a red-hot field, Bull and Wood proudly finished just 1.627 seconds behind the flying Kiwis and 0.545 seconds off the bronze medal.
It bested their Rio showing where they finished eighth.
Mihambo wins long jump gold
Uber-consistent Australian Brooke Stratton has finished seventh in the women's long jump at a second successive Olympics.
The national record holder produced her best jump of 6.83m in the third round of a remarkably tight final on Tuesday, where only 20cm separated the top eight.
Germany's Malaika Mihambo added the Tokyo Olympic gold to her 2019 world title with a clutch final-round effort of 7.00m.
American Brittney Reese edged out Nigeria's Ese Brume for the silver on countback after both women jumped 6.97m.
US veteran Reese now has a gold and two silvers from three successive Olympic campaigns.
Stratton, 28, has finished inside the top 10 at the past two Olympics and the two most recent world championships, while also claiming the silver medal at the 2018 Commonwealth Games on the Gold Coast.
Three Aussies into Olympic javelin final
Reigning world champion Kelsey-Lee Barber has regained her mojo in the nick of time to lead a full complement of three Australians into the women's javelin final at the Tokyo Olympics.
All year, Barber has struggled to get anywhere near the form that secured her Australia's only gold medal of the 2019 world titles in Doha.
She still looked way out of sorts in the opening two rounds of the qualifying competition on Tuesday and seemed certain to make an early exit.
But Barber was able to lift in the final round with her best throw of the year, a 62.59m effort which saw her qualify for Friday's final in third place overall.
Joining her in the final will be reigning Commonwealth champion Kathryn Mitchell (61.85m) and the unheralded MacKenzie Little, who threw a PB of 62.37m.
Title favourite Maria Andrejczyk from Poland led the qualifiers with 65.24m.
Hoy's sign of success in hometown Culcairn
A spark behind Andrew Hoy's success at the Tokyo Games was a sign in his hometown of Culcairn, the veteran equestrian eventer has revealed.
Hoy took his Olympics career medal haul from four to six in the space of two hours on Monday night, as two faultless showjumping rounds saw him win team silver alongside Kevin McNab and Shane Rose and individual bronze.
The 62-year-old triple gold medallist has long been decorated in his NSW birthplace, with a welcome sign proclaiming, 'Culcairn the home of Andrew Hoy'.
But UK-based Hoy said of his last pre-COVID-19 visit to Culcairn in 2019: "I was a little disappointed in the way the sign was.
"It was starting to look a little faded and I thought I have to do something to make sure they change it.
"Let's hope Culcairn has got the funding to upgrade the sign or otherwise I might I have to do it myself."
Hoy became Australia's oldest Olympic medallist at his eighth Games - another record for his country.
He now has three golds, two silvers and a bronze in his Games collection and has hinted that he is targeting the 2032 Brisbane Olympics when he would be 73.
Hoy said: "60 is the new 20. It's only when people keep mentioning my age that I actually think about it.
"I think we have to do it step by step and day by day.
"At this point I've got the most wonderful horse in Vassily de Lassos, who statistically is the fastest horse in the world.
"I would describe him for those not familiar with my sport as the Usain Bolt of the equestrian industry.
"I believe if Vassily de Lassos stays healthy and sound, and myself the same, I believe Paris (2024) is a strong possibility.
"In between Paris and Brisbane there is going to be Los Angeles (2028). A lot of work is to be done in between.
"This is what keeps me going in this industry. I've got a passion to work with the horse, one that comes from the heart."
Asked how he considered being Australia's oldest Olympic medallist, Hoy replied: "I don't think like that.
"I just think of myself as a kid that grew up on a farm in a little country town called Culcairn, New South Wales."
Australians book canoe sprint final berths
Australia's Tom Green will race in the final of the Olympic men's K1 1000 metres canoe sprint after finishing third in a lightning fast semi-final.
And teammates Alyce Wood and Alyssa Bull are set to top their eighth placing in Rio after booking a berth in the K2 500 metres women's final, beating home the Belarussian world champions.
Queenslander Green, who is mentored by three-time Olympic medallist Ken Wallace, came home behind heat winner Fernando Pimenta of Portugal, who clocked an Olympic best time of three minutes 22.942 seconds.
The 22-year-old was 1.67 seconds behind Pimenta while Australia's other paddler Jean van der Westhuyzen faded in the closing stages to finish at the back of the field.
In a tight women's semi-final, Wood and Bull looked in sparkling touch, finishing second behind New Zealand duo Caitlin Regal and Lisa Carrington, who is a two-time Olympic champion in the K1 200 metres.
With the Kiwis also clocking an Olympic best time thanks to a solid tailwind, world champions Volha Khudzenka and Maryna Litvinchuk crossed in third.
Australia's other duo, London Olympian Jo Bridgen-Jones and debutant Jaime Roberts missed qualification.
The finals will be held later Tuesday on Tokyo's Sea Forest Waterway course.
McSweyn eases into Olympic 1500m semis
Australia's great track medal hope Stewart McSweyn has lived up to his own lofty expectations with a dominant 1500m heat run on his Olympic debut in Tokyo.
The national record holder controlled the third of three heats from the front before easing off in the final straight to finish third in three minutes 36.39 seconds.
Joining McSweyn in Thursday's semi-finals will be countryman Oliver Hoare, who was third in the fastest of the heats in 3:36.09 with the top six advancing automatically.
The third Australian, Jye Edwards, was narrowly eliminated after finishing seventh in a rough-house opening-round encounter on Tuesday morning.
McSweyn, 26, is aiming to become the first Australian to claim an Olympic medal in the 1500m since the legendary Herb Elliott won gold at the 1960 Rome Games.
Reigning world champion and gold-medal favourite Timothy Cheruiyot from Kenya qualified second-fastest behind Belgian Ismael Debjani (3:36.00).
Boomers are back for must-win quarterfinal
It's do-or-die for the Boomers when they take on Argentina at Saitama Super Arena. The Aussies won all three games in tournament play to top Group B, while the Argentinians were a third-placed qualifier. The game tips off at 10:00pm [AEST], with Spain or Team USA to await the winner.
Stewart McSweyn, Jye Edwards, Oliver Hoare will all contest the men's 1500m today from 10:05am [AEST], while gold medals are being eyed off by Kurtis Marschall in the men's pole vault and Brooke Stratton in the women's long jump finals (11:50am AEST). The women's javelin throw also commences today, with Australia's own and world champion Kelsey-Lee Barber to lead our charge from 10:20am [AEST]. Hurdling ace Nick Hough also features later on and will fly the flag for Australia in his heats from 8:10pm [AEST].
Taliqua clancy and Mariafe Artacho del Solar have been super impressive throughout the beach volleyball tournament and they'll continue their charge against Canada in the quarterfinal from 11:00pm [AEST]. The Aussie pair have only dropped one set at Tokyo, but 2019 world champions Canada are yet to drop one.
Fresh off a stunning shootout win over the Netherlands, the Kookaburras have one more hurdle to jump before playing off for a gold medal, facing Germany at 8:00pm [AEST] in the semifinal. Can they continue their dream Tokyo run?
At long last, it's time for sports climbing! Catch Aussie Tom O'Halloran when he features in three disciplines -- speed, bouldering and lead -- tonight from 6:00pm [AEST]. To advance to the final, O'Halloran will need to finish in the top eight.
The Stingers face a huge quarterfinal clash against the Russian Olympic Committee from 8:50pm [AEST] and take an impressive 3-1 record into the contest, while it's semifinal galore in the canoe sprint, with the men's K1 and women's double racing from 11:00am [AEST].
Australian boxing lightweight Harry Garside has been the quiet achiever of these Games, and he'll fight for a medal tonight at 7:30pm [AEST] when he meets Kazakhstan's Zakir Safiullin in his quarterfinal bout.
Also featuring on Tuesday is Matthew Lydement who will step up to the platform one last time for Australia as he aims to weightlift to glory in the men's 109kg category from 2:50pm [AEST].
