Besides a salary of $100,000 a year, which they will actually work only between August and December 2013, six mates from the U.S., Canada, France, Brazil, UK and Ireland were declared on Friday winners of Tourism Australia's Best Jobs in the World promo.

The winners are considered lucky chaps because aside from the good pay and other perks, they will do tasks they enjoy the most.

The post of chief funster for New South Wales went to Andrew Smith of the U.S. He has the "boring" task of attending parties and events in NSW for the next couple of months.

Canadian Greg Snell snagged the position of wildlife caretaker in South Australia, which means his tasks include swimming with sea lions at Hopkins Island on the Eyre Peninsula.

Irishman Allan Dixon will be roughing it out with roos as an outback adventurer in the Northern Territory. The lone female winner, Elisa Detrez from France, will serve as a park ranger in Queensland.

Brazilian Roberto Seba got the job of lifestyle photographer in Melbourne. Brit Rich Keam has an intoxicating task as taste master in Western Australia.

The promo was supposed to pick only 6 winners, but Virgin Australia decided to become generous and awarded a seventh job to American Cameron Ernst who will be the air carrier's high flyer, shuttling between Australian cities and sharing with the world his best customer service experiences.

The promo attracted 330,000 applicants from 196 nations whom Tourism Australia whittled to 18 finalists who spent last week hurdling different challenges to prove they deserve the best jobs in the world marketing Australia.

Among their tests were to watch the premier of King Kong, the musical, in Melbourne, swing through vines at a rainforest retreat in Queensland and swim with sea creatures at the Ningaloo Reef in Western Australia.

Andrew McEvoy, managing director of Tourism Australia, said the winners went through a once-in-a-lifetime experience and embraced it with gusto.

The aim of the promo is to push Australia's holiday maker programme that contributed in 2012 $2.5 billion to the country's economy by young holiday makers spending an average of $13,000 during their stay in the land down under.

While the six gets the perks, Australia earns the dollars because 72 per cent of those who applied said they plan to apply for an Australian working holiday visa, of which 39 per cent plan to do it within the next six months.
