Priya Cooper, one of the Games' greats, won her ninth gold medal in three Paralympics in the S8 400m freestyle in the swimming pool to equal the national record of wins by 58-year-old wheelchair shooter Libby Kosmala.
The Australian team in total grabbed nine gold medals on Sunday, but seven-time gold medallist Louise Sauvage was not one of them.
The 27-year-old, who lit the cauldron at last Wednesday's opening ceremony, grabbed silver in the T54 800m event.
However, she was then told, along with the other athletes, that the race had to be re-run because of a sickening collision involving three of the wheelchair finalists after the 200m mark which led to the disqualification of Ireland's Patrice Dockery.
Little trouble
The race was won by Canadian world record holder Chantal Petitclerc, but now the race will be held for the second time on Thursday.
Cooper faced little trouble in defending her 400m freestyle title and described the win as the best of her career.
"This would have to be (the most special). It's my pet event. I love the 400," she said.
"I'm going to remember this for the rest of my life."
Also in the pool, Spain, who are second in the medals table, claimed the men's S9 400m freestyle through Jaime Serrano with Deborah Font taking the 100m SB12 breaststroke.
Spain also grabbed two more titles when Cesar Carlavilla took the men's T12 800m on the track and Alfonso Fidalgo won the men's F11 discus.
Dominated
China won four golds to take them to third in the medals table - with two coming in the women's powerlifting.
Li Ruifang set a world record lift of 137.5kg in the 75kg class and Cao Ping lifted her way to another world record of 125kg, in the 85kg division.
China also dominated in the table tennis with golds in the women's category, 4-5 and 6-10.
United States and Great Britain were fourth and fifth, both with 12 gold medals each.
Elsewhere, Poland's Piotr Czop took gold in the men's sabre category B, while compatriot Robert Wysmierski won silver.
Hong Kong won the A category sabre event, beating the French duo of Cyril More and Yvon Pacault.
Australia's Rollers claimed a berth in the men's wheelchair basketball medal rounds with a 69-54 win over Sweden. Their last preliminary round match is against 1998 world championship silver medallists, the Netherlands, on Monday.
