The 12-year-old boy who stars alongside Nicole Kidman and Hugh Jackman in the movie Australia is going to be this country's next leading man, says director Baz Luhrmann.

Brandon Walters, the Aboriginal boy plucked from obscurity by Luhrmann to appear in one of the country's most anticipated films, also stars in the new Tourism Australia advertising campaign created by Luhrmann.

He encourages visitors to Australia to lose themselves in our wide, brown land, saying "sometimes we gotta go walkabout".

"Paul Hogan was our last leading man," Luhrmann told the Nine Network.

"Our next leading man is about four foot high, (with) long, sort of gold hair, and is an Aboriginal boy."

Luhrmann has produced two mini-movies which show international visitors being transformed by the country when they visit Australia.

"The big idea in the movie is that this woman comes from far away and the land itself, the place itself, transforms her character," Luhrmann said.

"So when Tourism Australia came to me and they said `we're trying to tell the world why you should fly over a lot of beaches to come to ours', that really got me thinking.

"What if you didn't make an ad but you could see little movies, like little movie trailers, not about what's here but about the people that we want to come here?"

Luhrmann said the advertisements worked well alongside the movie, due for release on November 26.

"Lots and lots of money was going to be spent by our financier to promote this film and the fact is we share a brand, we share a name," he said.

Luhrmann said he was working hard to get the film finished in time, but a recent test screening of a rough cut in the US reported that the relationship between Jackman and Kidman "sizzles".
