The first OZTAG competitions started in the summer of 1992/1993 at Cronulla with 28 teams and St George with 12 teams. Since then OZTAG has enjoyed an extremely rapid growth throughout the country. The Australian Oztag Sports Association (AOSA) was formed in 1994 as an incorporated association. The AOSA currently aims to provide opportunities for people to participate at all levels, by developing, promoting and managing the game of OZTAG in Australia.

OZTAG is a non-tackling game and the rules are designed to encourage this. Passing, catching, tagging, evasive and kicking are the skills utilised in OZTAG. It is played over two 20 minutes periods with eight players from each team on the field - 70m x 50m (half a soccer/Rugby field).
