Waratahs, Brumbies have wins at Brisbane Tens opening day

The NSW Waratahs and ACT Brumbies have made both made a winning start to their Brisbane Global Rugby Tens campaigns.

Missing almost all of their stars, a second-string Tahs outfit prevailed 31-10 against French Top 14 side Pau with a slick performance at Suncorp Stadium.

Former Australian sevens star Cameron Clark relished in the shortened format, with his runs sparking some of NSW's best moments in attack against a Pau side featuring the likes of Conrad Smith, Ben Mowen and wildcard Carl Hayman on their teamsheet.

Halfback Jake Gordon, who scored one of their five tries, said the Waratahs had a "point to prove" at the tournament after a horror 2017, which included embarrassing Super Rugby defeats at home to the Southern Kings and Jaguares.

"Last year wasn't acceptable and Daryl (Gibson, coach) spoke to the team and made it very clear that this was one of our platforms to set (up) the year," he said.

The Brumbies, meanwhile, clawed from behind to win 17-12 against a Fiji side featuring former Queensland Reds winger Chris Kuridrani.

The younger brother of Wallabies centre Tevita Kuridrani, the 26-year-old outpointed Henry Speight to pounce on a wayward Brumbies kick and run 30m to the line to put Fiji ahead 12-5.

But Henry Speight and former Western Force star Chance Peni crossed in the second half for the Brumbies to snatch the win.

They were the only Australian sides to taste victory in their first-round games with the Melbourne Rebels and Reds both beaten.

As expected, Wallabies halfback Will Genia was denied a Brisbane homecoming and was not risked by the Rebels after suffering a fractured back at training.

Instead, a no-name side got off to a bright start in the opening match of the day, going 17-0 up over the Panasonic Wild Knights of Japan after two tries from Sama Malolo and one from Rowan Perry.

But they didn't score another point from there, with the Robbie Deans-coached Wild Knights mounting a remarkable comeback to win 19-17.

The Queensland Reds were towelled 29-7 by the Blues, conceding five tries in their first real outing under new coach Brad Thorn and appear to be a major work in progress.

"It puts a magnifying glass on your core skills, your tackle, one-on-ones, catch-pass. We were pretty scratchy today," Reds prop James Slipper said.
