Australia has caused a major upset in the men's volleyball competition, losing only a set to the highly ranked team from Poland.
The Volleyroos took the match 25-21, 25-22, 18-25, 25-22 and notched their first win of the London Games.
Conversely, it was the first defeat for the Poles who are the world's fourth-ranked team.
Thomas Edgar, the Queenslander who stands at 212cm, led Australia with 22 spikes.
"We took a long time to heat up and get to our best," he said.
"But we do have a level to match the top-level teams."
Australia sits fifth of the six-team group on four points.
It can make the quarter-finals if the winless Great Britain team defeats Argentina later on Day 10.
"Great Britain can play some good volleyball, but Argentina are one of the high-level teams so we'd be surprised (if Great Britain won)," Edgar said.
Bulgaria leads group A with nine points, with Poland also on nine.
Poland coach Zbigniew Bartman was frank about his team's performance.
"We didn't play very well. We didn't play good tactics and if we play like that we should expect to lose," he said.
"If we play like we did today, we could lose against anybody."
