A man escaped unscathed after base jumping off a Hume Highway bridge over Allens Creek in Douglas Park at the weekend.

He was spotted launching himself off Moolgun Bridge, about 60 metres from the ground, on Saturday afternoon. 

Within seconds a red, white and black parachute was seen floating to the ground.

The man reportedly disappeared quickly after landing.

Base jumping is illegal in Australia so many jumpers go to Europe to practise their jumps and improve their skills.

Two Australians have died since August last year  while base jumping overseas.

A 33-year-old Australian jumper died in August after jumping 2525 metres from a French mountain peak. 

Alex Duncan, 26, from Manly, died in September after he jumped from a 2243-metre peak in the Swiss Alps.

In Australia, the National Parks and Wildlife Service issues $300 fines for base jumping, while local councils can issue $110 fines for failing to comply with signage erected by council on infrastructure. 

Rescue costs of up to $20,000 were required for a man found hanging off a cliff face after he base jumped in the Blue Mountains in 2005.
