Winger Drew Mitchell and prop Ben Alexander have become the latest Australia players to commit their futures to the Wallaby cause.
Waratahs back Mitchell and Brumbies forward Alexander both featured on Australia's tour of Europe last November, with Mitchell claiming a hat-trick of tries in the emphatic 59-16 win over Six Nations champions France, and have signed two-year extensions.
They follow in the footsteps of Adam Ashley-Cooper and Stephen Moore in penning new deals with the Australian Rugby Union.
Both players cited the chance to face the 2013 British and Irish Lions tourists as a major reason in their decisions to re-sign, and ARU chief executive John O'Neill said: "The most pleasing aspect of the past week is to hear how our leading players are still driven by the desire to make the Wallabies the best in the world, that they feel a sense of unfinished business until the goal is achieved, and that the opportunity to play against the Lions is so appealing.
"That tells me the culture around the team is strong. This is a young side, starting to taste success via the win against the All Blacks last October and the European champions France a few weeks later.
"They are ranked number two in the world but still not satisfied. I think all Australian rugby fans will be heartened by their commitment to continue improving and returning precious metal to the trophy cabinet.
"I'm delighted Drew and Ben have joined Stephen Moore and Adam Ashley-Cooper in re-committing to Australian Rugby for a further two years."
