Ireland skipper Peter O’Mahony admits it would be ‘incredible’ to complete a series win over Australia in Sydney this weekend.

Joe Schmidt’s Six Nations champions levelled their series against the Wallabies with a 26-21 win in Melbourne on Saturday.

It means they can complete a long-overdue series win Down Under by taking the third Test and O’Mahony is desperate to claim a piece of history.

Tries from Andrew Conway and Tadhg Furlong saw Ireland recover after the Wallabies touched down through Kurtley Beale inside a mere 80 seconds at AAMI Park.

The tourists were in total control as Johnny Sexton booted four penalties before Jack McGrath was sin-binned late on, allowing Taniela Tupou grab a third Australian try and leave them with five points as the clock wound down. O’Mahony knows how hard it will be to complete the job on Saturday.

“It took a week’s training and probably one of the best performances of the year to put that Australian side away.

They are one of the best sides in the world for a reason and it was incredibly physical and intense out there,” he told RTE.

“It would have been a nightmare to go to Sydney next week and for it to be a dead rubber.

I think it was 1979 the last time Ireland won over here. That shows how hard it is.

“We’ve put ourselves in place to win a series and it would be an incredible piece of history over here.”
