Australia batter Marnus Labuschagne is confident he will return to the peak of his powers and find his best form during the upcoming ICC World Test Championship series against Bangladesh.

The Aussies will host Bangladesh for a two-match series from August 13 as part of the ongoing World Test Championship cycle and Labuschagne looks set to get the opportunity to lockdown the crucial position at No.3 inside Australia's top-order despite some indifferent recent form with the bat.

Labuschagne hasn't scored a Test century in more than three years despite some good contributions during Australia's 4-1 Ashes series triumph over England at the start of the year, but the former No.1 ranked Test batter believes he is not far away from regaining his touch and is targeting a strong showing during the upcoming home series with Bangladesh.

"It's certainly very important to start these two Tests well," Labuschagne said.

"When you're on the road playing for probably the last seven or eight years straight, this is the longest break I've had. There have been times where I've tried to get things in order, but I just run out of time to fully commit to those small changes.

"It's been really nice to go back and find my best form and what it looks like for me to play at my best. The preparation over the last few weeks here with Australia has been great for that. Hopefully we can see the results off the back of all the hard work."

Labuschagne admitted he has been too focused on scoring bulk runs in recent times and he is now more open minded about his game and believes the big scores will come if he trusts his preparation.

"When you've missed out a few times, you get a little greedy and start searching for runs and you are not letting the game come to you," Labuschagne added.

"It's really important for me to not get too invested in the runs. We want the runs, but we want the process and that is what I am looking for.

"The runs will come as the journey goes on if I keep trusting my game. I think that's what I did really well through that period that I went really well. I trusted my game, trusted how I went about batting, reading the game and understanding what the team needed from me in that moment. That's what I'm looking forward to."

The two-match series between Australia and Bangladesh commences in Darwin on August 13, with the second match of the fixture in Mackay from August 22.

Australia currently sit on top of the World Test Championship standings, while Bangladesh are fourth.
