Jillaroos coach Brad Donald has given the strong indication fullback Sam Bremner will be fit in time for Sunday's semi-final showdown with Canada after missing the opening three games of the tournament through injury. 

A frustrated Bremner is the only Jillaroo yet to feature in Donald's rotating squad after copping a knock to the shin at training in the lead-up to Australia's World Cup campaign.

Donald was confident Bremner could walk into the semi-final clash with no match fitness.

"Hopefully she does [play Sunday]," Donald said. 

"She's close and ran this morning. We're excited to bring her into the side. She's a bundle of energy and is driving us nuts in camp at the moment.

"She just wants to run so we're looking forward to getting her on the field."

If Bremner misses Sunday's clash, the Jillaroos coach fell short on confirming her spot in the World Cup final should the side get through. 

"We haven't really discussed that," Donald said.

"We're just trying to keep her motivated which is not hard. She's been on the game ready and is doing everything she can to get ready for Sunday.

"If she doesn't play on Sunday we'll cross that bridge but I'm confident she will."

The 25-year-old has had a string of bad luck in 2017 having missed Australia's Anzac Test match victory over New Zealand in April after copping a head knock during the captains run, and suffering an ankle injury in the interstate challenge win for NSW.  

Donald admitted Bremner would be "devastated" at the prospect of missing the entire tournament.

"She would be, anyone from that group would be," Donald said.

"We often talk about player 25, 26 and 27 that trained hard to make the squad but didn't make it. 

"They're a big part of the success of this team because they pushed these girls to be as good as they are today."

The Jillaroos coach has his team firing in time for the all-important finals and faces a selection headache with every player in the squad putting their hand up for selection.

Bremner's replacement for the first two games, Nakia Davis-Welsh, was among the Jillaroos' best, while Corban McGregor was strong in the win over Canada.

Halfback Maddie Studdon continues to put pressure on incumbent halfback Caitlin Moran, while hat-tricks to forwards Vanessa Foliaki and Elianna Walton in the 88-0 victory over the Ravens have done their chances of a semi-final berth no harm. 

"Right from the outset and I spoke to the girls [after the game], we've asked them to aim up no matter what position it is," Donald said.

"We've had halves play lock and centre. Every single one of them I have 100 per cent confidence that if somebody drew 17 names out of a hat those girls would go out and play for each other."
