Tim Cahill boosted Australia's hopes of winning next month's AFC Asian Cup when he confirmed on Thursday that he would be fit for the tournament opener against Oman on 8 July.

The 27-year-old Everton attacking midfielder has not played since March when he fractured a metatarsal in his left foot against Sheffield United in the English Premier League.

Cahill said he would accompany the Socceroos for their friendly in Singapore on 30 June, but won't play until Australia's Cup campaign kicks off in Bangkok a week later.

"I've got another X-ray to go but they've given me the all clear for the Asian Cup," Cahill said Thursday.

"It's feeling well. It's just good to be back, good to be involved."

During his recovery at home Cahill has been working with national team strength and conditioning coach Anthony Crea.

Crea said there was still a need to proceed with caution but he had no doubt the FIFA World Cup hero would play against Oman.

"He's coming along really well," Crea said.

"We've still got the reins on him now because he wants to do a little bit more, but we're just being a little bit cautious, because yeah, he'll be ready to play the Asian Cup from game one.

"He'll definitely be ready. After the last scans he had, the doctor's really happy with him. The Everton physio came out and he was really happy so that's a good thing.

"We basically will travel together on the 20th (of June) with the team. He'll probably train with me individually a couple of days before our first game. He'll miss the Singapore game when we're in Singapore but that's not a big drama.

"At the moment we're still on straight line running and just basically building his core fitness strength up with gym work.

"Once we get over to Singapore we'll start doing a bit more ball work and working on pivoting and start moving from side to side."

The Australian squad for the Asian Cup will be announced on Friday.
