Matildas mania has reached a fever pitch ahead of their semi-final match against England.

75,000 fans will pack into Sydney's Stadium Australia to watch both teams clash for a spot in the title decider.

Former Matilda and Football Australia's Head of Women's Football Sarah Walsh says the team's in uncharted territory as they enter their first semi-final- but they want to go all the way.

"They're hard to not love. Coming from the group stages, this groundswell here has been unbelievable. I've even been shocked how they've been able to convert non-sporting fans into sporting fans."
