The Hockeyroos unleashed a dominant few minutes in the second quarter in their clash with Great Britain in London to beat the home side 4-2 win in London.

After a goalless first quarter, Australia came out firing in the second - blasting two goals in less than a minute to flip the match on its head.

The first goal came via a penalty corner that was coolly handled by Madison Fitzpatrick, launching an unstoppable drag flick past the keeper. Fourteen seconds later following a turnover in midfield, Brooke Peris drove forward and while sliding, cleverly chipped the ball over the onrushing goalkeeper.

The double strike looked to have rattled the home team, and before long, Jane Claxton added a third goal in the 23rd minute following a deflection from a Great Britain stick. The goals didn't stop after half time, with Mariah Williams able to put through a sweetly-struck reverse shot in the 37th minute to make it 4-0.

Great Britain did fight back in the second half scoring two unanswered goals to set up a thrilling finish.

Hockeyroos coach Paul Gaudoin highlighted the team's improvement after a mixed first quarter.

"We weathered a bit of a storm and struggled to get the ball out of defence," he said.

"The second half was a lot better, we started to put some speculative balls through and created some really good chances, and put some balls past a very good goalkeeper which was pleasing."

Despite the win, Gaudoin still sees areas for improvement.

"It was pretty tight but no doubt pleasing to find a way to win and keep our lead," he said.

"We want to be smarter and better, to control the ball when we're up by a goal or two."

The Hockeyroos' next match is on Sunday night against fourth-placed Germany in Krefeld.
