The Great Britain women's water polo team suffered a 16-3 loss to Australia on Wednesday night.
Two defeats from their first two matches leaves Team GB propping up the Group B table in their first Olympic campaign.
Their opponents led from start to finish, dominating in every area of the game and running away with the match 16-3.
Australia stunned the home team by flying into a 3-0 lead within seven minutes, but the crowd at the Water Polo Arena were given something to cheer about when Chloe Wilcox clawed one back from a man-up situation.
The sides started the second quarter at 3-1, but Australia again dominated their hosts to score three unanswered goals. Wilcox, 25, from Carlisle, found the back of the net once more to take the teams into half-time at 6-2.
The team from Down Under, who call themselves the Stingers, lived up to their nickname in the third quarter as they pushed on into double-figures.
Francesca Painter-Snell, 25, from Manchester, scored Great Britain's only goal from a penalty, but Australia cruised into the final period with an 11-3 lead.
The Stingers, wearing green and gold caps, were ruthless once again in the fourth quarter, hammering home five more unanswered goals.
Australian centre back Rowie Webster netted five goals, while Ash Southern scored a hat-trick. Gemma Beardsworth and Kate Gynther fired home two each, to leave Sophie Smith, Bronwen Knox, Glencora Ralph and Nicola Zagame to score one each.
Australia's shooting was far more effective, with their 16 goals coming from 31 attempts (51.6%), compared to Great Britain scoring their three from 19 shots - a conversion rate of just 15.8%. The home side will now dust themselves down and turn their attention to their third match, against Italy, on Friday.
