Tennis Carnivale is on Saturday at the Weston Creek Tennis Club after a downpour in September forced its rescheduling.
From 1pm to 4pm on Saturday there will be hot shots and cardio tennis, a jumping castle, face painting, a barbecue, DJ and free social tennis and clinics.
There will also be a "come as your favourite player" dress up competition.
It all takes place in Dillon Close, Weston. The day is supporting Ronald McDonald House Canberra.
