Group 18 is the name of a junior rugby league competition on the far north coast of New South Wales, Australia. Currently, the group has no senior competition. Prior to 2005, there was a joint Gold Coast-Group 18 competition which fielded teams from both the Queensland and New South Wales sides of the border. With the Burleigh Bears joining the Queensland Cup in 1997 and the Tweed Heads Seagulls joining them in 2003, the combined competition started to lose some of its lustre. In 2005, it was dissolved with the remaining Queensland teams forming a dedicated Gold Coast competition and the NSW teams joining an expanded Group 1 competition, now named Northern Rivers Regional Rugby League. Both Group 1 and Group 18 run junior competitions.

Seniors

The Group 18 Senior Rugby League Premiership amalgamated with Group 1 Rugby League in 2005 to form the Northern Rivers Regional Rugby League, and was thus discontinued in its own right.
