Captain-for-the-night Tim Cahill put in 50 minutes and won a penalty in Australia's 4-0 win over Oman in the 2015 Asian Cup.
The result confirms the Socceroos' place in the quarterfinals of the tournament. Their next match, against South Korea on January 17 will determine whether that progress is as group winners or runners-up.
The Taeguk Warriors beat Kuwait, 1-0, to secure their own qualification for the next round.
Both Australia and South Korea have won their first two matches of Asian Cup, but the Warriors have edged each of their first games by single goal, whereas the Socceroos appear to have finally cracked the code of coach Ange Postecoglou's tactics. The team has now scored eight goals in two games in this tournament, each provided by a different scorer: not bad considering it managed just 12 in its last 12 matches, and relied on Tim Cahill to knock in seven of those.
The suddenly free-scoring Socceroos head into their group stage finale with confidence, and Timmy is tweeting up a storm.
