Laurie Weeks is hungry for more Test football having enjoyed the briefest taste in 2014.

Weeks, who signed a two-year contract extension with Melbourne Rebels on Wednesday, played for Australia off the bench in two Tests this season, and he can hardly wait to get started in Super Rugby next year to try to force himself into the squad for the Rugby World Cup to be held in England.

Weeks, 28, said that his career had been kick-started under coach Tony McGahan this year, and that resulted in his Test debut. "I only had a brief taste of it and with the upcoming World Cup I just want more," Weeks said. "I would love to taste international rugby again and that's a huge motivator for me."

Wallabies coach Michael Cheika forecast personnel, technical and tactical changes to try to turn the set-piece into a weapon after the disappointing European tour. The Wallabies scrum was lambasted after being demolished by England in their final Test of the year, and Weeks said that Australian rugby needed to change its mind-set.

"In general I think that as Australians we don't value the scrum," Weeks said. "A lot of that comes from that spectators don't see it as an exciting part of the game. But in reality it's integral so we need to focus a lot more attention on it. You speak to any of the front-rowers throughout Australia and they're battling that mind-set. They are keen to improve as scrummagers and improve our reputation, but they need support as well."

Cheika said the Wallabies may have to start fighting illegal tactics with their own scrum hi-jinks, and Weeks agreed saying the Australians had to forget about a "fair go" for their opposition. "You speak to anyone who's played in France or Europe and it's all about who can cheat the best, and I think that's something we need to develop," Weeks said.

The foundation player, the 2009 Super Rugby Rookie of the Year, has made 53 appearances for the Rebels and made his Wallabies debut against France at Etihad Stadium in June. He won two more caps before an injury sustained in the National Rugby Championship ruled him out of the Wallabies' end-of-year tour of Europe.

Weeks said "I just thought about where I really enjoy playing footy, and that's here in Melbourne",

"I am really excited about where we are as a team," he said of the Rebels. "Our coaching staff is at the best level it has ever been, and I am really excited about continuing to work with Tony McGahan. The coaches and program here really helped me become a Wallaby, and in the last year Tony has helped me play my best footy, so it's great working under him."

McGahan paid tribute to Weeks, saying the prop's attitude "sees him constantly seek improvement, which, coupled with Laurie's playing ability, make him a wonderful asset to the club".
