The exciting 28-year old's three goals (following one he scored against Wellington last week) has also sent the Glory to the top of the A-League ladder as the only team with a maximum six points from the first two rounds.

Keogh's 74th minute strike from inside the box appeared to be heading wide and found the back of the net after rebounding off the Roar's James Donachie.

Donachie will be happy that the goal was attributed to Keogh, as he already is credited with an own goal, from the Roar's loss to Adelaide in round 1.

The Roar sits in ninth spot in the table after two rounds, with only fellow 2012/14 grand finalist Western Sydney Wanderers, behind them.

Brisbane led 1-0 at half-time on Sunday and appeared to have the run of play.

There were a few nervous moments for both sides before the Roar broke the deadlock in the 39th minute.

Henrique found himself on the end of a terrific long ball that had the Glory defence struggling.

He crossed perfectly into the path of Mensur Kurtisi, who slotted it past Perth keeper Danny Vukovic.

But Perth came out firing after half-time and Keogh levelled the scores just three minutes after the restart.

He made no mistake from the spot after being bought down inside the box by Jade North.

Keogh could have given Glory the lead a few minutes later, but his close-range header hit Roar keeper Jamie Young.

That miss could have been costly, as Henrique gave the visitors the lead again in the 55th minute, smashing a well-timed strike from just outside the box past Vukovic.

The game looked destined for a draw, but Keogh again popped up in the first minute of injury time, his header from a Scott Jamieson corner giving the home side an unlikely victory.

Perth heads to Adelaide on Sunday in a bid to keep its winning start to the season going, while the Roar hosts Sydney FC on Friday night in a bid for its first win.

The nib Stadium crowd of 8789 on Sunday took the A-League attendance for round to 106,082, breaking the record set in the opening round of last season (100,998).
