Australia have awarded new contracts to forwards Liam Gill, James Slipper and Rob Simmons until the end of the 2015 World Cup.
The contract extensions mean the trio will also remain at the Queensland Reds.
Flanker Gill, 21, was one of the most impressive performers in the Wallabies' series defeat to the British & Irish Lions.
"The rugby World Cup in 2015 is a long-term goal but that is a long way down the track and anything could happen," Gill said.
"I'm certainly excited to be playing in Australia and for Queensland and if I'm lucky enough to fall under the Wallaby category, I can't wait for it."
Slipper has won 37 caps since his 2010 debut and the 24-year-old prop will be expected to provide competition for veteran front rowers Benn Robinson and Ben Alexander.
Lock Simmons, also 24, partners Australia captain James Horwill in the second row for Queensland Reds and will hope to add to his tally of 26 caps following the retirement of veteran Nathan Sharpe.
