Kantarovski strike denies the leaders
After a scoreless first half, Jamie Maclaren opened the scoring after a neat piece of skill on 52 minutes.
Brisbane were headed for victory before Kantarovski poked home from a corner on 71 minutes.
The result means Brisbane move two points clear on top, ahead of Melbourne Victory's clash with Adelaide United tonight.
Newcastle move above Melbourne City up to 12 points into fifth spot.
Jets youngster Braedyn Crowley missed an absolute gilt-edged sitter in the first half.
The Roar took the lead early in the second half with a well-taken goal by Olyroo Maclaren.
Roar winger Brandon Borrello made a strong run from the centre circle into the middle of the Jets defence. He played a nice ball to the right where Maclaren found space.
Maclaren controlled well and cut back to open up the goalmouth and curled a left-foot shot into the far side of the goal.
Newcastle levelled 19 minutes later when Roar failed to clear a David Carney corner kick that swung menacingly in the windy conditions.
Jets substitute Ryan Kitto pounced on the bouncing ball in the Roar penalty box and passed to defender Ben Kantarovski, who toe-poked in from close range.
The second half was entertaining with a series of attacks and counter-attacks.
"I thought we were the better side in the second half," Maclaren said.
"It was hard to break them down. We created enough chances to win the game and (a draw) is pretty disappointing."
