Prue Watt ensured Australia added to its gold tally on the last day in the pool at the Paralympics, winning the SB13 breaststroke.
Watt finished in a time of 1:19.19, an Oceania record, some 1.12 seconds clear of Germany's Elena Krawzow in second place.
Kelley Becherer of the United State finished third to collect her fourth medal of the Games.
"I've wanted that so much for so long," Watt said.
"I can't believe it at this point - I'm sure it will kick in soon.
"I'm incredibly excited by that swim. I'm just relieved I guess as well."
In the final swimming event, Australia finished third in the 4x100m 34 points medley relay, taking Matt Cowdrey's medal haul to eight - five of which were gold.
For much of the race the Australian team of Michael Anderson, Cowdrey, Brenden Hall and Matthew Levy was out of the medal positions before, in the final straight, Levy edged in front of Ukraine's Yevheniy Bohodayko.
Australia ended the swimming event with 18 golds (second behind China's 24), seven silvers and 12 bronze.
