Australia eye WTC final

A relaxed and confident Australia head into the third and final Test against South Africa in Sydney eyeing a series sweep and a berth in the World Test Championship (WTC) final to cap a dominant home summer.

Pat Cummins's team, who sealed the series with an innings victory in Melbourne last week, can book their place in the WTC decider at The Oval in June with victory at the Sydney Cricket Ground.

Even with pace stalwart Mitchell Starc and all-rounder Cameron Green sidelined by finger injuries, Australia have ample depth and the freedom to experiment leading in to next month's four-Test tour of India.

In recent years, the SCG has not lived up to its spin-friendly billing but ground staff say the pitch should offer turn.

That could mean a role for Ashton Agar in Australia's 11 and a first Test for the left-arm spinner since 2017.

Cummins said selectors had decided on the lineup but would not reveal it until the toss on Wednesday.

The match should offer "a really good prep" for India, the paceman added.

South Africa, beaten in all facets in the Boxing Day Test, have one forced change, with number three Theunis de Bruyn returning home for the birth of his daughter.

Rassie van der Dussen may be in line for a recall, having been replaced by De Bruyn after the series-opening defeat in Brisbane.
