Keen swimmers such as Destinie, 3, and Will, 4, have the chance to win $10,000 this week.
Paul Sadler Swimland in Braybrook is holding a week-long party to celebrate having its 10 millionth customer nationally.
Fourteen families enrolled at the organisation’s 14 centres will be randomly selected to try a key that could unlock a prize chest.
The Braybrook centre will also surprise one family with a year of free swimming lessons for each of its children.
