Australia breathed a sigh of relief when a last-quarter surge secured a 2-1 win over Great Britain in their fourth pool match in Brazil.
The world No.1 Kookaburras booked their second win of the tournament and moved to third in their pool, with Spain and Belgium the joint leaders.
The Australians dominated the Brits but were frustrated again by their inability to find the back of the net, with 17 shots on goal to their opponent's eight.
Aran Zalewski broke the drought midway through the final quarter when he collected the spoils thanks to some handy lead-up work by Simon Orchard and Daniel Beale.
Beale and Orchard also had a hand in the second goal with five minutes remaining.
The Australians took advantage of a massive numerical advantage with Jake Whetton getting the last touch across the line.
Ashley Jackson grabbed a consolation goal for the Brits with just over two minutes remaining.
It was the Kookaburras' second win, against two losses in their four games, and moved them to third in the pool with four teams from six advancing to the quarter-finals.
