Scott Sio returns to Australia team for Rugby World Cup final against New Zealand

Scott Sio has returned to Australia's lineup for Saturday's Rugby World Cup final against New Zealand at Twickenham.

The number one missed the Wallabies' 29-15 victory over Argentina in the semi-finals due to injury.

The 24-year-old has now been declared fit for the showdown and will go straight into the front row, sending James Slipper back to the bench.

Sio's return is the only change made by head coach Michael Cheika, who is one win away from claiming his first World Cup since taking charge of Australia last year.

Isreal Folau will keep his place in the starting XV, while David Pocock will continue in the number eight role following his return from an injury.

Meanwhile, New Zealand are unchanged for the final.
