Australia's star striker, Sam Kerr, found herself in the starting lineup at the Women's World Cup for the first time during Wednesday's semi-final clash against England in Sydney.

The 29-year-old captain had made appearances as a substitute in the previous two matches due to a calf injury that significantly limited her participation in the World Cup.

Her inclusion in coach Tony Gustavsson's starting eleven provides a significant boost to the co-hosts' prospects of making it to the World Cup final for the very first time.

The victor of the semi-final in Sydney will square off against Spain in the final on Sunday, also set to be held at Stadium Australia.

Kerr takes the field in place of Emily van Egmond, marking one of two changes, alongside Clare Polkinghorne, who replaces fellow defender Alanna Kennedy.

The European champions, England, have maintained an unchanged lineup from their quarterfinal victory over Colombia, where they secured a 2-1 win.

Known for her prolific scoring record, Kerr averages a goal every other game for Australia.

Despite being anticipated as a key figure for her home World Cup, she saw her first action in the Round of 16, entering the match in the 80th minute during a 2-0 victory against Denmark.

In the quarterfinal against France, Coach Gustavsson introduced her in the second half.

Kerr subsequently scored during the penalty shootout, playing a crucial role as Australia progressed with a 7-6 victory on penalties.
