Louise Quinn headed the winner as Republic of Ireland beat Australia 3-2 in front of 3,314 supporters at Tallaght Stadium.
But it was Lucy Quinn who struck an early blow for the hosts, her free-kick hitting the post and rebounding in off goalkeeper Mackenzie Arnold.
Emily Gielnik’s lay-off found Mary Fowler for a 15th-minute equaliser and although Arnold did well to deny Heather Payne, she was beaten by Denise O’Sullivan’s deflected effort.
There was also a wicked deflection at the other end, Fowler levelling for a second time past Courtney Brosnan to leave it all square at the break.
Louise Quinn powered in a header early in the second half to restore the lead, while there was no goal for striker Sam Kerr on her 100th appearance for The Matildas.
Ireland next play at home to Sweden on 21 October, in a World Cup Qualifying group game.
