Australia's assistant coach Daniel Vettori admitted that with just a day left in the third Test in Brisbane, a draw is the most likely result in the offing.

Vettori said losing Josh Hazlewood did affect Australia's game plan, but the rain breaks helped the pace duo of Mitchell Starc and Pat Cummins without any additional burden.

"Weather allowed us to operate in terms of breaks with Mitch and Patty able to come back on multiple occasions. If it had been full 90 overs, it would have been a lot tougher to manage. We always have the luxury to bowl Nathan (Lyon). So that alleviated a little bit of the concern.

"Because of the breaks, it didn't feel like we pushed them too hard, and it was a tricky situation at the end there where the ball was incredibly soft and getting wet, but to try and push them just that little bit longer to try and get that last wicket," Vettori said.

"Probably that's the only time where we felt they were slightly extended, but so far it feels like the norm," he added.
