GB rally to hold Australia
Great Britain came from 3-0 down to draw 3-3 against world number ones Australia and keep their semi-final hopes alive.
The hosts were 3-0 down early in the second half before they made their charge in exhilarating fashion to leave the Kookaburras wondering what had hit them.
Two goals from Matt Ford and another from Mark Knowles had seemingly put Australia in control but Jonty Clarke began the fightback before captain Barry Middleton and James Tindall completed the recovery.
GB had won only five of 47 meetings with their rivals and had not beaten them since the 1988 Olympic semi-final in Seoul when a certain Sean Kerly scored a hat-trick on the way to gold.
And while this was not a victory it certainly felt like one as the team came back from the dead against the best side in the world.
It means both will probably need a draw in their final Pool A matches to make the last four.
Australia missed two early half-chances through Matt Gohdes and Glenn Turner before taking a seventh-minute lead when Ford's run down the left byline evaded two tackles before squeezing a shot under goalkeeper James Fair from a narrow angle.
Matt Daly's reverse-stick shot only just missed being turned in by Clarke before the Kookaburras caught the Britain defence napping.
Clarke was sent to the sin-bin, and while the hosts were still reorganising, Tim Deavin's quick pass into the circle came off Dan Fox's foot to present Ford with a simple chance from close in.
Great Britain were in danger of being overrun in the opening 20 minutes but found a foothold in the game in the latter stages of the half but their only penalty corner saw Ashley Jackson's effort blocked.
The interval came at the wrong time for Jason Lee's side as they were just starting to build momentum and Australia were able to regroup.
When Knowles drilled a low shot inside Fair's left-hand post it looked like the game was up but GB showed the battling qualities which may yet get them into the semi-finals.
Clarke's run along the byline from out on the right caused concern in the Kookaburras' defence but he had a stroke of luck when his cross hit Chris Ciriello and bounced over the line.
But there was no fortune about their well-rehearsed penalty corner move which saw Middleton dive in at the far post to deflect in Richard Smith's pass.
The tempo immediately went up a couple of notches as GB sensed a vulnerability in Australia which Argentina had exploited earlier in the week when they came from 2-0 down to draw.
And they found the weak spot again four minutes from time when Tindall picked up Middleton's cut-back to power in a deflected shot which goalkeeper Nathan Burgers could not keep out.
Even a desperate video referral could not save the Kookaburras, who have now conceded two-goal and three-goal leads in their last two matches.
