With just one day to go until Australia's cricket tour of Sri Lanka begins, the Australian team's batting order remains uncertain.

Speculation is rising over the potential replacement of teenager Sam Konstas as Usman Khawaja's opening partner, a partnership that helped Australia secure victory over India in the first Test of the year.

During Australia's 2023 subcontinent tour, Travis Head thrived as an opener, and he has indicated that his return to the top of the order - and Konstas' potential demotion - will depend on the conditions in Galle.

โ€œI think we'll get on the ground [in Sri Lanka] and see what we're dealing with,โ€ Travis Head said, via cricket.com.

โ€œI've said this before, I'm very flexible about where I go and where I need to bat for this team, and how they think we're going to win the game.โ€

โ€œOnce we get on the ground in Sri Lanka and see the wicket then the powers that be will make a call on what they think is the best make-up to win a test match.โ€

While Konstas' aggressive, T20-style approach against the Indian bowlers in late December and early January proved successful, the recent centre-wicket practice at the ICC Academy in Dubai saw neither Head nor Konstas open the batting. 

Instead, it was regular Test number three Marnus Labuschagne who partnered with Usman Khawaja.

โ€œI've always been an opener,โ€ Konstas told cricket.com.

โ€œBut if I'm going to bat four or five here, I'd love to take the opportunity. A few games I've batted at four or five, so I don't think it's a big change for me the way I go about things.โ€

It's possible that Konstas may be omitted entirely, especially with Head suggesting to reporters on Monday that Josh Inglis could make his Test debut by stepping into his role in the middle order.

Once the batting order is determined, it won't necessarily remain set for the entire match. One bold strategy being considered for the unpredictable Galle pitch is the possibility of altering the batting order between innings.

โ€œWhat you're trying to do is line it up to be flexible to help win a Test match,โ€ said Head.

โ€œSo if that means being more flexible on day one, what's not to say in the second innings when it does turn and get extreme that the order may change.โ€

โ€œWhy doesn't the order change, why can't we be flexible, where can we win a Test match?โ€

โ€œI think people are open to it, and the game's evolving.โ€

This flexibility extends to the bowling lineup as well, with Head hinting that Scott Boland could be dropped in favour of a three-spinner attack.

It appears a spin-heavy strategy will be prioritised, with left-arm orthodox Matt Kuhnemann and rising star Todd Murphy both firmly in contention to join Nathan Lyon in the lineup.

The opening match of the Sri Lanka Test series, where all will be revealed, begins at 3:30pm AEDT on January 29.
