Vic death may be BASE jump gone wrong

A NSW man has died in Victoria in what appears to be a BASE jump gone wrong.

Emergency services were called to an accident near the Omega tower, a 432m structure at Gifford, about 200km east of Melbourne, just before 2.30pm (AEDT) on Saturday.

The Omega tower is a well-known site for illegal BASE jumping, an activity where people jump from fixed objects and use a parachute to break their fall.

Ambulance Victoria spokesman John Mullens said ground crews and a helicopter were dispatched but the 23-year-old man was difficult to access.

"It came through as a base jump man in his 20s believed to be deceased," he said.

Emergency services workers had to be directed to the site by people who had been with the man, Mr Mullens told AAP.

"It took a little while to get in," he said.

"He was deceased."

Police described the death as a "parachute incident".

Mr Mullens said he believed the Omega tower, a navigation antenna and transmitter, was a BASE jump site.

The Omega tower is the tallest structure in Australia, more than 100 metres higher than the Q1 Tower on the Gold Coast and Sydney Tower.

BASE is an acronym for building, antenna, span (bridge), and earth (cliffs) - the four places where jumpers launch from.
