Twenty20-style Fast5 netball to hit Australian shores

New Zealand are the defending champions and Australia are the in-form team, but it's the unpredictability of Fast5 netball which could see any of the six nations lining up for short-form honours take out the title in Melbourne this weekend.

Vying to overcome the traditional trans-Tasman powerhouses are England, South Africa, Jamaica and underdogs Malawi in netball's version of Twenty20 cricket.

New Zealand have won five of the past six tournaments while Australia are chasing history and the only trophy missing from their impressive silverware cabinet.

Captains from all sides were in agreeance on Thursday that the 24-minute, five-a-side matches with hybrid rules levelled the playing field, with long-range multiple point shots and power plays often proving the difference.

Australia Fast5 Diamonds captain Susan Pettitt said her side was boosted by the inclusion of shooters Gretel Tippet and Caitlin Thwaites fresh from a winning Constellation Cup campaign against the Silver Ferns.

She playfully nominated rival Kiwi Fast5 skipper Maria Tutaia's skill in nailing the long shots as a reason why Australia is yet to claim a win the fast and furious tournament.

"Fast 5 is built for Maria Tutaia, she's a great long-bomb shooter but we've got some shooters in our team this year who have been really practising that and they're looking good so we're hopefully going to come out on the weekend and do well," Pettitt said.

England, champions in 2011 and runners-up in 2010 and 2012, boast a strong side which features the likes of Geva Mentor, Jo Harten and Ama Agbeze - regulars in the now defunct trans-Tasman league, while South Africa's Helen Housby will be keen to impress on Australian soil ahead of her debut with the NSW Swifts in the new National Netball League next year.

Jamaica are without their all-conquering shooter Romelda Aiken, who headlines the new NNL Collingwood side next year, but captain Althea Byfield confidently said her side has what it takes to win.

"To me, it's just regular netball, the rules are a little bit different, but it's five of us and five of them. It's anybody's game," Byfield said.

"It's challenging in the sense that in normal netball you want to protect the post, but in this situation, you want to give them the post because it's just one point."

Malawi captain Grace Mwafulirwa bravely shook off the underdog tag and said the Queens, featuring Melbourne Vixens new signing Mwai Kumwenda, would be competitive due to the nature of the game.

"We're ready. We're going to go out there with all our heart to do our best. [Fast5] is unpredictable."
