The Aussie Sharks have continued their world-beating ways in Paris, while the Hockeyroos remain unbeaten with a win over Spain.

Here's how Australia's teams have done so far on day eight of the Olympics.

Sharks claim another victim

After dropping their first game against Spain, the Australian men's water polo have been unstoppable at the Paris Aquatics Centre.

Beating two-time defending Olympic gold medallists Serbia was a shock, taking down hosts France displayed remarkable focus, but the Sharks have now pulled off arguably their finest feat in Paris.

Hungary is the most decorated team in men's water polo, with nine Olympic gold medals between 1932 and 2008, plus four world championships and four World Cup wins.

And the Sharks handled them with aplomb yet again on day eight.

They didn't panic when Hungary struck first through Krisztian Manhercz, and held firm when they went behind 5-4 on the stroke of half-time.

In the second half, the Aussies trailed regularly, including heading into the final frame down 7-6, which became 8-6 with 6:48 left.

But again the Sharks refused to give in to the moment, with Nathan Power and Marcus Berehulak getting them back to 8-8, and Power scoring his second with 48 seconds left.

It turned out to be the match-winner as Hungary's last-ditch shot hit the right post and floated perilously in front of goal before Nic Porter claimed it.

Hockeyroos stay perfect heading into quarterfinals

A final-minute goal has taken the Hockeyroos to the top of their Olympic pool and secured a quarterfinal against China in Paris.

Needing a two-goal win against Spain to leapfrog Argentina — and importantly avoid European dangers Belgium or Germany in a final-eight knockout — Australia started brilliantly on Saturday.

Mariah Williams beat two Spanish defenders with a wicked left-to-right aerial drag, then found Alice Arnott's stick with a pinpoint cross as Australia led after just 92 seconds.

Spain eventually broke through 40 minutes later when Lola Reira converted her penalty stroke late in the third term, but the Hockeyroos finished stronger, with Stephanie Kershaw continuing her fine tournament with a deflection goal from a penalty corner with five minutes to go.

Spain then replaced its goalkeeper with a field player inside the final two minutes as they rolled the dice to find an equaliser.

It backfired though, with the Hockeyroos turning them over and captain Kaitlin Nobbs slapping home the winner in the final minute.

It followed a 3-3 draw against Argentina and three other wins from pool action, top spot in the pool meaning they will avoid the imperious Netherlands until the gold-medal game.

Australia won three golds in four Olympics between 1988 and 2000, but have not made the podium since the third of those in Sydney.
