A two-hour honesty session helped rally the Australian men's water polo team, who kept their Olympic campaign alive with a 13-8 win over Greece.
It was a sudden-death game for the two teams in their last pool match and the Sharks are now into the quarter-finals, probably against Serbia.
It is the first time Australia have made the men's quarter-finals since the 2000 Games, when they lost to Yugoslavia.
Coach John Fox described Sunday's meeting as "a painful process", but said it had the desired effect.
"This Olympics is pressure like no other tournament and the fact that it goes for two weeks, you can have a team up and running in the first couple of days," Fox said.
"If something starts to break down, you have to address it straight away.
"I have to be honest, it hasn't been all rosy for us.
"Yesterday was just critical ... everyone was held accountable, right down to the physio."
Australia's shooting, a big problem for them previously in this tournament, improved and their goals came from 23 shots.
The two teams went goal-for-goal in the first quarter and Australia led 3-2.
Australia then steadily pulled clear, scoring 3-1 in the third term.
Rhys Howden scored a hat-trick while Richie Campbell, Jamie Beadsworth and Billy Miller had two each.
"What we put in place today will hold us in good stead - if we apply that from here on in, we should stand a good chance," Beadsworth said.
"There were some fairly glaring issues that were arising again and again, especially with the extra man.
"We spent a good chunk of the meeting dealing with them and fortunately we applied them (tactics) today and they came off."
On Sunday, Beadsworth watched his sister Gemma and her teammates beat China in a penalty shootout to reach the semi-finals.
