Australia's Northern Territory is cracking down on its unofficial tourism slogan, 'CU in the NT', over concerns it's degrading towards women.

The controversial campaign was launched in 2016 by the independent brand NT Unofficial with the tagline "The top end. Different from the bottom end".

The aim was to promote travel awareness to the Northern Territory - and show off the state's "excellent sense of humour".

Since then it's taken off with NT Unofficial selling a large amount of merchandise in stores and at popular markets at Nightcliff and Mindil Beach.
