Glenn Maxwell is unfazed at being overlooked as a bowler as Australia eye another comprehensive beating of Pakistan on Australia Day.

Maxwell's offspin slot has been pinched by South Australian Travis Head ahead of the final game of the five-match series at Adelaide Oval on Thursday - the hosts lead the series 3-1.

Maxwell has found imposing from with the bat and says he's unconcerned at being snubbed with the ball by captain Steve Smith.

"It's just about me working hard and continuing to be an option if he needs me," Maxwell said.

"It's as simple as that. It's not something I have really worried about too much.

"In the first game Heady bowled 10 overs for 28 and I didn't do that too many times in my career.

"He has been bowling really well and been a great offspin option for us so I have just got to be that other option if need be."

Maxwell has made 161 runs, averaging more than 53 and at a strike-rate bettering 127, in the series against the Pakistanis, including a swashbuckling 78 last-start.

"It has been really pleasing to be feeling consistent at the crease with the way I have been moving, and striking the ball quite consistently," he said.

"To come back and get two 50s out of three innings and feel like I have hit the ball nicely and doing it my way, was really pleasing."
