Birtinya is built around Lake Kawana, which includes a 2 kilometres buoyed course for flat water competitions. The Lake Kawana Community Centre located beside the lake on Sportsmans Drive provides 15 spaces (halls and meeting rooms) together with commercial kitchen facilities and smaller kitchenettes for community events. It is operated by the Sunshine Coast Regional council. The centre was officially opened on 5 November 2005 by City of Caloundra mayor Don Aldous.
