Rugby Australia, formerly the Australian Rugby Union, confirmed in the wake of the Western Force being axed from Super Rugby a transition period will be implemented for next season to keep Force players in Australian.

Australian Super Rugby teams are currently subject to a $5 million salary cap across a 30-man playing roster, which excludes top-up funding for Wallabies players, but those numbers are expected to rise for the 2018 season.

Western Force stars Ben McCalman, Curtis Rona, Matt Phillip and Billy Meakes are currently on the Wallabies spring tour and are yet to sign with clubs for next season.

Brumbies boss Michael Thomson said their squad is almost complete but confirmed they would return to the player market if the rules are changed.

"We're very close to being finalised for next year with only one or two [contracts] that we're still working through at the moment, we're basically sorted," Thomson said.

"We're comfortable to accommodate some of the players who come onto the market who don't have places to play, but it would have to be a transitional arrangement rather than permanent."

Rugby Australia high performance manager Ben Whitaker said the governing body have been working with teams and the Rugby Union Players' Association to keep Australia's best talent in the country.

"Currently our Super Rugby teams can carry core playing squads of 30 players and it is likely that we'll need to review that number as the teams finalise their squads for 2018," Whitaker said.

"Unfortunately there isn't a perfect solution that provides a completely equitable outcome for every team in terms of talent access, but we believe this short-term measure will enable us to keep a number of talented players in Australian rugby.

"Ultimately, what we hope to achieve is to retain our best players in Australia, support the transition of former Western Force players, and give each team the opportunity to develop their squads and achieve winning outcomes next season."

The Brumbies won their conference and were the only Australian team to turn a profit this season, but Thomson said it was still unclear what effect the four-team format will have on the club's bottom line.

Thomson remained confident they could remain in the green on the back of ACT rugby thriving at the grassroots level and believes the Brumbies can breakthrough for their first title since 2004.

"The ACT schoolboys won the national championship, the Canberra Vikings won the NRC minor premiership and the ACT women's finished runners-up in the national 15s comp," Thomson said.

"At the Brumbies we want to set ourselves to win the competition, not just the Australian conference but the whole competition, and to do that you've got beat everyone.

"We've got eight home games next year with matches against the Waratahs, Crusaders and Reds which probably makes for a more attractive season.

"We have a very nice draw with two Sunday afternoon games and with reduced prices for membership there are lots of reasons for people to come out and if we see good turnouts then we should be able to hit our numbers."

The Brumbies season kicks off against the Sunwolves in Tokyo on February 24, while their first home game is against the Sharks in round four on March 17.
