The Starlight Super Swim Challenge is an annual fundraising event in its eighth year where participants swim laps to raise money for sick children across Australia. Since its inception in 2019, the event has raised $17 million, with this year's goal set at $4.3 million. Tomorrow features a special double donations promotion where $125,000 in matching funds from partners will double all donations made, and participants can join individually or in teams at pools nationwide.
