Fisher is expected to be confirmed as Gloucester coach for the next three seasons, with England's Rugby Football Union meets on Wednesday at 1.30am Canberra time.

He will leave halfway through a two-year deal, working as a co-coach with Stephen Larkham, who  will take over the reins solo for next season.

Fisher joins a procession of talent leaving the ARU system at the end of the Super Rugby season, along with Brumbies captain Ben Mowen and Wallabies lock Kane Douglas.

But Fisher didn't think it was a concern for Aussie rugby, with a limited number of spots available here meaning there would always be talent heading overseas.

"It's natural turnover, natural attrition, there's a lot of good coaches, a lot of good players [who] don't get an opportunity," he said.

"I think it's just a natural cycle, it's neither good nor bad, it's just a fact of life.

"As one person goes, a more-than-capable person takes their place.

"It's a small market here, there's only so many playing and coaching positions available."

The Brumbies are tipped to re-sign halfback Michael Dowsett on a two-year deal on Wednesday.

They're also hoping to welcome back six players for their crucial final-round clash against the Western Force that will decide whether they make the Super Rugby finals.

Wallabies Matt Toomua, Pat McCabe, Joe Tomane and Sam Carter could all return from injury, along with hooker Josh Mann-Rea and Andrew Smith.

Fisher didn't think it was a concern having so many players come back in for such an important game.

The Brumbies are in sixth position, but have the bye this weekend, while the Western Force, Auckland Blues and Waikato Chiefs all have games and are just four points behind them.

Depending on round 18's results, the Brumbies could be anywhere from sixth to ninth going into their clash against the Force.

"Most of the guys have played a fair bit of footy, they've just missed [a few weeks]," Fisher said.

"Toomua's played three Tests [for the Wallabies], Patty McCabe played the Test series, Carter played in the first Test.

"They've had a couple of weeks off, but I think they'll fit back into things reasonably quickly."

The Force face the Queensland Reds, who are out of finals contention, but will still pose a serious threat to a side that hasn't experienced the pressure of finals football before.

It's something the Brumbies tasted the last two seasons and Fisher is hoping it will stand them in good stead in the run home.

They agonisingly missed out on the finals in 2012 after a shock final-round loss to the Blues at Canberra Stadium, before they made last year's grand final.

"We have a lot of respect for [the Force], they've had a very good year, they play a well-structured game their players understand," Fisher said.

"I can't speak for how they'll handle [the pressure], we've only got to worry about ourselves.

"Last year's experience will stand us in good stead, but in the end it's 80 minutes and you've got to play well and what we're focused on at the moment is trying to get out best side together ... but having been there before, you would hope that's an advantage."

Most of the players have a few days off before returning to training at the end of the week.
