Want to win a trip to Australia’s Northern Territory? Hie thee to Twitter.

Here at Gadling, we’re not above shameless self-promotion. Particularly when the prize is a free trip to Australia for one lucky winner.

Our blogger-at-large, Andrew Evans, just returned from a month-long trip to Australia and he’s hosting a Twitter-based contest to send a winner (plus a friend) on a similar journey.

The best part? Entering is simple. Just tweet @WheresAndrew with the reason that the Northern Territory is the place you’d most like to visit in Australia. Be sure to include the hashtag #Takeme2NT or your entry won’t count – that leaves just 130 characters!

The rules are fairly simple. You must follow Andrew on Twitter, Fan the Northern Territorry on Facebook, and compose a tweet answering the above question.

The winner of the “best tweet” (decided by an external body in the Northern Territory) will win two round-trip tickets from the winner’s nearest flight departure city to either Darwin or Alice Springs, Northern Territory, Australia and a five-day rental of a Britz 4WD camper van.

Hurry, the contest ends February 11. Full contest details are avaiable here.
