Wallabies front-rowers Stephen Moore and Ben Alexander will continue to ply their trade in Australia until at least 2015.
The pair, who are both Canberra-based with the Brumbies, have extended their current deals for a further two years - taking them through until the conclusion of the next Rugby World Cup in England.
"I've still got a lot that I would like to achieve both with the Brumbies and the Wallabies, and I can't do that by heading overseas," said 30-year-old Moore, who is the most capped hooker in Australian Test history.
Moore's importance to the Wallabies is such that prior to sustaining a hamstring injury in training before Australia's Test against South Africa in Perth last year, he had missed just 14 of the 69 Tests played by the national side in the five seasons between 2008 and 2012.
Alexander, who rocketed into the spotlight in 2008 after virtually coming from nowhere to make the Wallabies side in Robbie Deans' first year as national coach, has now played 48 Tests since his debut against France in Sydney.
The 28-year-old begins 2013 poised to become just the fourth Australian prop to achieve a half century of appearances, following on from Al Baxter (69), Ewen McKenzie (51) and current front-row colleague Benn Robinson (currently 56), who surpassed 50 Tests last year.
As many as eight current Wallabies are within range of 50 Test appearances as the year begins.
"While last year was an eventful one, and provided a lot of challenges for everyone associated with the Wallabies, it was a tight group," said Alexander.
"We stuck together and showed what it meant to us to represent Australia.
"The wins in Argentina, where none of us had ever played a Test before, and against England at Twickenham, were incredibly special performances.
"The team showed great heart and togetherness in the face of extreme adversity.
"While we might not be ranked number one in the world at the moment [Australia is ranked third, but only decimal points behind South Africa], I truly believe we have the potential to get there.
"Last year's run of injuries has exposed a lot more players, created a lot more competition for places and a lot greater depth in each position, which will help moving forward.
"If you look at the All Blacks, they've got two or three guys who can step up in every position. That's where we are getting to, which is why I believe there is so much more to come from the Wallabies."
