If Samoa thought the Wallabies disrespected them, they must really be cheesed off with bookmakers, who continue to give the Pacific Island giantkillers no chance of winning the Rugby World Cup.

While prime minister Tuilaepa Sailele Malielegaoi believes Samoa are capable of going all the way this year after stunning the Wallabies on Sunday, Australian bookies remain far from unconvinced.

One agency has the 10th-ranked Samoans listed as 250-1 bolters to lift the Webb Ellis Cup, with punters still able to get as much as 380-1 on Betfair.

Wallabies hooker Stephen Moore, who received front-row viewing of the Samoan threat during Australia's shock 32-23 loss in Sydney, says such long odds are ridiculous.

"They'll cause some headaches. They're a good team," Moore said on Wednesday.

Samoa, quarter-finalists in 1991 and 1995, have been thrust into the the so-called Group of Death for RWC11 in New Zealand in September and October.

Defending champions South Africa are expected to top the group, with Samoa's clash with Wales in Hamilton on September 18 likely to decide second place in Pool D.

Should Samoa finish runner-up in their group and Australia - who have Ireland and Italy in their Pool C - top theirs, the Wallabies will face a rematch against the Pacific Islanders in the quarter-finals in Wellington on October 8.

"Defeating Australia, which is the second-ranked team and is twice world champions, shows Samoa can win the World Cup," Samoan PM Malielegaoi says.

Regardless of how they fare, Samoa are assured great support at the World Cup, with their pool game on September 30 against the Springboks at the 30,000-seat North Harbour Stadium in Auckland one of three matches at the tournament already sold out.
