Co-hosts Australia laboured initially in the absence of injured captain Sam Kerr but a second-half penalty from Steph Catley got them off to a solid start at the Women's World Cup with a 1-0 win over Ireland in Group B on Thursday.
The news that striker Kerr had been ruled out by a calf injury stunned the record crowd of 75,784 as it filtered into Stadium Australia but Catley stepped up to take the captain's armband and score the decisive goal in the 52nd minute.
