Queen guitarist Brian May has lashed out at a camera crew moments after touching down in Australia.

The world-famous musician took exception to a 7NEWS camera operator, pushing him and describing him as a “parasite” for filming him greeting fans.

May and his entourage had just touched down for their Australian tour and were posing for photographs at Brisbane Airport when he lost his nerve.

“You’ve got to stop that,” May shouted at the cameraman.

The 72-year-old then threatened the cameraman as he continued to film.

“Excuse me, we said no. Is this going to get ugly? You put this down or else something ugly happens, do you understand?”

Later, the cameraman, who is also a Queen fan, pulled out his mobile phone to get a personal video when the guitarist attacked him once again.

“You’re so clever aren’t you? What a parasite you are just leave us alone would ya, don't you understand?” he shouted.

May regularly posts videos of his movements online but appears less impressed to be filmed by others.

Fans will get to see Queen in concert in Brisbane on Thursday before a bushfire relief concert in Sydney on Sunday, two dates in Melbourne and a show in Perth on February 23.

The band, featuring Adam Lambert on lead vocals, will then head to Adelaide and the Gold Coast for the final dates of the tour.
