Jenna Forrester has set a new Australian record to win the 400m IM at the short course championships in Sydney.

Forrester earlier finished second to Iona Anderson in the 200m backstroke.

Flynn Southam claimed victory in the 100m freestyle and called out his rivals for the upcoming world championships in Beijing in December.

Jenna Forrester's outstanding 2026 has continued at the Australian Short Course Championships in Sydney, lowering the Australian women's 400m individual medley record on her way to gold.

The 23-year-old beat Ellen Fullerton's 17-year-old mark with a time of 4:28.39, taking 0.33 seconds off the record.

The time was comfortably under the qualifying standard for the upcoming world championships in Beijing.

Remarkably, Forrester had only just competed in the 200 backstroke, finishing second to Iona Anderson, also swimming under the qualification time for Beijing.
