The Australian netball captain Sharelle McMahon made a strong comeback from injury, leading the Diamonds to a crushing 71-40 victory over Jamaica on the Gold Coast.
After missing the first two Test wins with a badly corked thigh, McMahon played three quarters of the lop-sided encounter as Australia completed a 3-nil series whitewash of the Sunshine Girls.
The 106-cap veteran, who turned 33 on Thursday, started at goal shooter and combined beautifully with Natalie Medhurst in the goal circle as the Diamonds took hold of the match in the opening term.
Jamaica now head the New Zealand to play 2 matches against New Zealand in Christchurch on Wednesday and in Napier on Saturday.
