Australia 575 for 9 dec (Sutherland 210, Healy 99, Mooney 78, Gardner 65) beat South Africa 76 (Brown 5-21) and 215 (Tucker 64, Tryon 64) by an innings and 284 runs

Australia's versatile and talented attack overcame a resolute South Africa mustering belated fight to complete a comprehensive Test victory at the WACA late on day three.

Having been pushed in tight T20I and ODI series victories, Australia's experience in red-ball cricket came to the fore as they clinched the inaugural multi-series between the teams 12-4.

Australia's attack were made to work against gritty batting on a surface that flattened out as the match wore on, but their bowling depth shone with six bowlers taking wickets in South Africa's second innings of 215.

After being routed for 76 on day one, their lowest ever Test score, South Africa had been in danger of humiliatingly losing within two days when they crashed to 13 for 3.

South Africa resumed their second innings at 67 for 3 with Brits and Tucker hoping to continue their rearguard after defying Australia late on day two with a half-century stand.

In warm conditions, Brits looked tentative as Australia's seamers targeted a dangerous length outside off-stump. Darcie Brown's extra pace proved a handful and she was unlucky not to take a wicket when Brits edged just in front of second slip.

She also had Tucker top-edging over wicketkeeper Healy, but the batters settled on a sun-baked surface offering little movement. They put away rare loose deliveries and were untroubled by short deliveries coming off the wicket relatively slowly compared to earlier in the match.

Tucker had a couple of anxious moments as she neared her half-century, including miss-hitting a pull shot off Ellyse Perry that narrowly was out of reach of Alana King running back from square leg.

But Tucker regained her composure and notched her half-century on the very next delivery. Healy resisted using her three frontline spinners and she was rewarded with her faith in the seamers when Perry ended the 96-run partnership after Brits edged low to second slip where replays confirmed that Phoebe Litchfield had her fingers under the ball.

But Australia were again made to wait as Tryon showcased a mix of power and finesse to continually hit through the off-side as Healy finally reverted to spin.

It almost paid off immediately when Sophie Molineux, playing her first international since late 2021, had Tryon inside edging onto her pad only for Healy to drop a tough chance moments before lunch.

The pressure built on Tucker, who was undone by extra bounce as she chipped a return catch that was well taken by Gardner. She trudged off in disappointment, but earned a strong ovation from the crowd after making 64 off 180 balls in four hours at the crease.

King was denied a first wicket of the match when Mooney dropped a straightforward catch at slip to reprieve Tryon, who capitalised to notch her half-century soon after.

But an Australia victory was always just a matter of time as Sutherland capped a memorable match by clean bowling Tryon with hometown hero King claiming the final wicket to punctuate Test cricket's return to the WACA.
