New Rugby Australia chief executive Raelene Castle has left the door ajar for the Western Force to return to the fold in 2021, but the Indo Pacific Rugby Championship remains in limbo.

Castle flew into Perth on Thursday in a bid to help the governing body regain the trust of disgruntled Western Force fans.

She also met with billionaire mining magnate Andrew Forrest on Friday to continue negotiations regarding his proposed IPRC competition, which he hopes to launch early next year.

GETTY IMAGES Raelene Castle's first job has been to repair relations with Western Australia after the messy Force axing.

The Perth-based franchise might not have to wait long before being welcomed back into the fold.

The current Super Rugby broadcast deal ends in 2020, and the SANZAAR joint partnership between South Africa, New Zealand, Australia, and Argentina remains uncertain beyond then.

Castle said that could open the door for the Force's return.

"We all have to remain open minded. Because who knows what the new version might look like come 2021," Castle said.

The Force will be back in competition by early next year if Forrest can launch his six-team IPRC competition.

But he has been in fruitless negotiations with Rugby Australia for months now, with the governing body still yet to give their tick of approval that is needed before World Rugby can approve the new competition.

The major stumbling block surrounds whether players who feature in the IPRC will be made eligible for Wallabies selection or not.

The IPRC is scheduled to run alongside the early part of the Super Rugby season.

"We had some early, very short discussions about that today," Castle said of her meeting with Forrest.

"And it's always about compromise, about how that can work.

"He [Forrest] is realistic. He knows these things aren't always perfect and don't happen easily.

"I think of course he's a bit frustrated. But he also understands the reality."

Rugby Australia are still sweating on an ASIC investigation that is looking into their decision to axe the Force and alleged inappropriate dealings with the Melbourne Rebels.

Those findings could be handed down any day.

Castle's visit to Perth hasn't been easy, but she said it was important to hear first-hand the level of anger held by WA's rugby community.

"There's trust to be rebuilt, and the start of that has happened by coming here and having those conversations," she said.
