A music expert says that Tourism Australia might face legal issues soon, with the release of it's latest ad jingle that is silimar with the theme song of Disney's Mickey Mouse Club.

Donna Weston, popular music program convenor of Queensland Conservatorium of Music, said that the chord progression of Tourism Australia's jingle was "80 per cent the same" with the Mickey Mouse theme tune.

"The 'dada dada' is almost exact - same chords and very similar melody," Ms Weston said.

"The rest starts off each phrase with the same chord progressions as Mickey, but then moves to something else for the rest of the phrase.

"If it were a different beat, people wouldn't even pick it up, but it is that happy, marching feel that tunes people's ears in."

In February, the Federal Court ruled that Men At Work must pay for taking some parts of the pub classic Down Under from Kookaburra Sits In The Old Gum Tree.

Ms Weston said that the recent dispute involving Down Under was "a lot less obvious" than the blend of Mickey Mouse and Tourism Australia.

According to her, the chord progression matches were likely between songs, but other resemblances may put Tourism Australia in a legal challenge if Disney would push through with it.

"There are thousands of songs written on the same chord progression," she said.

"What is interesting about this one, is that there are snippets of melody that are similar, and the tempo and rhythm is the same - just enough for you to have that 'tip of the tongue' feeling.

"If someone at Disney wanted to be pedantic, they would have a strong case."

"We didn't write the song," a spokeswoman from Tourism Australia said, adding that the jingle was also compared with other songs.

"I've heard [it compared to] Vegemite, Aeroplane Jelly, Discovery Channel, all the usual things.

"The very nature of jingles is that you listen to it and it sticks in your head, and that's why [the creators] are in advertising."

The spokeswoman could not confirm though if copyright checks have been completed.

The jingle was produced by Josh Abrahams and the ad was directed by Michael Gracey.

Disney has yet to comment on the issue.
