People from Sydney are pretentious. In Adelaide, they are so cold they need to wear a quilt to go out. In Melbourne there are filthy beaches and people drinking coffee out of avocados.

These are the facts — if you believe Tourism NT's latest advertising campaign, which aims to lure more young people to the Northern Territory.

The $660,000 "Get out of the state you are in" campaign was launched on Friday, starring comedians Tanya Hennessy, Harley Breen and Alex Williamson.

With recent year-on-year statistics showing visitor numbers to the NT down more than 5 per cent, the new campaign aims to attract 18-35-year-olds, who they hope will share the video clips on social media.

In one of the advertisements, Harley Breen from Melbourne says he would prefer to be cultured than have a good time, compares Aboriginal art unfavourably with his city's street graffiti and nearly gags at a cafe as he sips a "single-origin slow pour, pour-over avocino" from a cup made from half an avocado.

In another, Hennessy explains things people in Sydney apparently never say: "There are not enough firework events in this city" and "I don't even care what high school you went to 10 years ago".

Williamson dresses for a night on the town in Adelaide, which includes wearing three jackets, two beanies and a quilt, and implores a friend to join him for a rave at his local library.

Not just for grey nomads

Advertising commentator and creative director of Campaign Edge, Dee Madigan, liked the latest offerings from Tourism NT.

"I think the Territory has been that place where the grey nomads go and the really worthy people go," Ms Madigan said.

"But I think that they are going for a younger market who also wants to have a bit of fun, and I think that these ads tap into that a bit."

She said the success of the cheeky-yet-unofficial CU in the NT campaign, which was a social media sensation, may have fed into the brief for the latest series of ads.

"I think what happened was that people actually laughed so much and it got so much traction that I think it might have fed into the brief for this one a little bit, which was be a little bit more cheeky than we have done in the past," Ms Madigan said.

Ms Madigan said that having established comedians star in the commercials made sense, because comedians often had large social media followings.
