Northern Territory Football League

The Northern Territory Football League (NTFL) is an Australian rules football competition, operating in Greater Darwin and the Northern Territory, formerly run by the Northern Territory Football League Incorporated and, since 3 September 2001, is a business name of the AFL Northern Territory Limited. The NTFL is currently branded "TIO NTFL" under sponsorship naming rights held by Allianz, which owns the Territory Insurance Office (TIO). It operates a semi-professional senior men's competition as well as competitions for women (NTFL Women's) and underagers (U12-U18 boys and girls) (NTFL Juniors).

It is one of few (and the highest level) Australian football competitions played during the Australian Summer with the season beginning in October and ending in March, because cricket cannot be played during the wet season, due to high levels of rain, resulting in the football and cricket seasons being swapped. It regularly attracts high-profile semi-professional players from interstate competitions due to its lack of salary cap and the timing of the season, which allows players to play extra matches during the off-season of other competitions. While most other Australian football competitions in Australia operate during the southern hemisphere winter, the NTFL chooses to play in the Northern Territory's 'wet season' from October to March, primarily due to hard playing surfaces and the need to play cricket during the 'dry season'.
