Australia will begin its first home One Day International series since 2020 on Sunday as they take on Zimbabwe in Townsville.

Straight after that three-match series, they will play another against New Zealand in Cairns.

With a World Cup just next year, these matches have increased significance as each side looks to hit top form.

Here are all the big talking points

3. Can Zimbabwe pull off an upset?

It might be slipping under the radar, but Zimbabwe is having something of a purple patch.

Last month they beat Bangladesh in both ODI and T2O series' while their new superstar, Sikandar Raza, scored 379 runs across both formats.

Little was expected of them against India and after losing by ten wickets and five wickets in the first two matches, they seemed a long way off.

Yet, they well and truly showed they belonged in the final match, falling just thirteen runs short of India's 289.

Raza was the star again with 115, but a new bowler also potentially emerged as the young Brad Evans took 5 wickets.

While these performances are hardly earth-shattering, they represent a distinct improvement on the Zimbabwe of the past and Australia must be careful not to underestimate them.

A win is surely too much to expect but, in unusual conditions for the Australians, the Raza-led Chevrons could pose a good challenge.
