Republic of Ireland international Heather Payne says they're fully aware of the threat posed by Australia.
Vera Pauw's side take on the hosts in their opening Group B match at the World Cup this Thursday in Sydney.
With preparations continuing, Payne says getting to see Australia play France in a friendly last Friday has been a help.
The Irish squad trained earlier this morning, with Denise O'Sullivan taking some part in the session.
The midfielder is recovering after sustaining a shin injury in last Friday's friendly against Colombia.
