Australia captain Sam Kerr confirmed she will be available for the Matildas' final group-stage encounter with Canada after missing their first two World Cup matches with a calf injury.

The Matildas’ chances of progressing from Group B hang in the balance after Thursday's surprise 3-2 defeat to Nigeria in Brisbane, and only victory over the Olympic champions on Monday will see Tony Gustavsson’s side qualify for the last 16, barring a draw scenario that will still rely on the Republic of Ireland beating Nigeria.

Kerr, her country’s top goal-scorer of either gender, is not just Australia’s strongest weapon — she is more symbolically the poster-woman for this tournament both in her native country and, arguably, around the world.

The Chelsea striker would not confirm if the encouraging update would mean the home support would see her start in Melbourne, telling a press conference: "I feel good. The plan has always been the same, miss the first two games then reassess.

"I'm feeling good, I was out on the pitch today. As good as I can be.

"I would love to tell you guys everything — but you know being in sport a long time, that's a massive thing the opposition wants to know.

"And like Tony said yesterday it's going to go down to the wire. I'm definitely going to be available, but how we decide to use that is not to be given to the opposition, I think is the main thing.

"Obviously the plan for me is to be involved and I'm excited. I've done everything I can, and no matter what happens I know that I’ve given everything just in the last 10 days, in the last four years, I’ve given everything to be here."

Kerr, who has scored 63 goals across 121 caps for Australia, joked: "I have the biggest calves in the world, so I’m not sure why it decided to play up the day before the World Cup, but that's sport for you, isn't it?

"It was obviously disappointing, and then I had to kind of suck it up. I'm part of a team, I'm not part of an individual sport.

"It's not about me, and that's what I've done over the last however many days it's been.

"I’ve had to put the team first, and I've been lucky enough over the past couple of years, I've always been on the pitch for this team, and I've always had team-mates that have not been on the pitch and supported me and got me over the line.

"That's been my role the last 10 days and to be honest with you, it's an honour to be here. I feel really lucky and privileged to be here.

"I look around women's football at the moment and I'm lucky that it’s only a small injury compared to some other people. You look at Keira Walsh last night, so you have to look at the bright side of everything.

"It kind of sucks but there's always someone worse off."
