The result also ensured Eddie Bone's 200th game resulted in a win, along with fellow milestone-reaching defender Karri McMahon (150) and goalkeeper Jocelyn Bartram (50).

With the Australian backline holding firm under mounting pressure and the clock ticking down towards a third straight Hockeyroos match being decided by a penalty shootout, Steph Kershaw was able to thread a pass through to Stewart to bury home the winner with just 12 seconds remaining.

While pleased to snatch maximum points, Hockeyroos Coach Paul Gaudoin admitted his team was somewhat fortunate to be in front when it counted, although he praised the players' ability to fight it out to the end and be rewarded.

"It was pleasing to get the win in the end but I would imagine Great Britain would be disappointed with the outcome," Gaudoin said.

"We were quite messy with the ball and we need to get better with our execution of skill. If you don't have that then it's hard to do any tactics, so we've got be cleaner on the ball to give our front group a chance to do something of quality."

"If we're scratching out a win with the performance we put out tonight, when we start getting it together it will be great."

A seesawing first quarter saw both sides trade penalty corner opportunities without success, before Great Britain opened the scoring through Sarah Robinson in the 18th minute.

Fourth time was a charm for the visitors after Australia were unable to clear their lines despite Bartram making three saves in quick succession before Kershaw hit an equaliser in the 26^th minute.

Bartram was awarded the Player of the Match in her 50th appearance for her role in keeping Great Britain to one goal despite Australia trailing 11-33 in the circle penetrations count for the match.
