At least two people jumped from the Exchange Tower in Perths CBD — a 150-metre, 40-storey building — around 8.45am.
Two people were captured on video jumping from one of the buildings highest points, plummeting to the ground before suddenly opening parachutes and gliding to safety, but up to four were involved, according to some witnesses.
Western Australia police were not immediately able to comment. The management of the tower, contacted by 10 daily, responded “no comment”.
BASE jumpers leap from 40-storey office block in Perth
It is unclear how the people made their way to the top of the building before many commuters had even made their way to the office on Tuesday.
A group of suit-wearing BASE jumpers have left passers-by in the Perth CBD shocked by leaping off the top of one of the citys tallest buildings in broad daylight before parachuting down to a park below.
The WA Police condemned the stunt in which at least two jumpers were filmed standing on the top of the 40-storey Exchange Tower, before leaping off and landing in a patch of grass.
The jumpers then landed on a grassed area at Elizabeth Quay before packing up their parachutes and rushing to the Supreme Court Gardens.
“This type of behaviour is reckless and irresponsible and the WA Police force does not condone this type of behaviour,” a police spokesman said.
“It could have cost any one of them their lives, it also could have cost someone on the ground their life as well,” Ms Roberts said.
A WA Police spokesperson told Yahoo News Australia they are aware of footage of the incident circulating on social media and are looking into the incident.
Alex Bennett, who works on the ninth floor of a nearby building, said he was confused when he saw the jumpers.
“I walked over to the window and saw one dude landing right here with a parachute and I was like, What the hell?
BASE jumping is illegal in Australia and the spokesperson said police are enquiring to see if trespass has been committed.
“I kept looking and another two guys landed, and they just grabbed their chutes and kind of legged it around the corner.”
“There was a bunch of people around here just kind of looking around like what the hell is going on?, and yeah, they just like full-pace legged it across the road and then they were gone,” he said.

A spokesman for Exchange Tower would not comment on how the jumpers managed to gain access to the buildings roof.
Mrs Roberts said she understood the jumpers wore suits in order to blend in and gain access to the building.
“Clearly that building needs to have its security reviewed, particularly how people got onto the roof.”
In 2014, two thrillseekers successfully completed two separate BASE jumps from the peak of Bluff Knoll in Western Australias Stirling Ranges.
The men jumped from one of the states tallest peaks before flying at high speed to the ground using wingsuits.
Neither of the men were injured and the activity was not deemed illegal at the time, but the department that manages the area cautioned about the risk of “inappropriate” activity.
A BASE jumper was injured in 2015 when he jumped off the top of the Queens Riverside apartment building in Perth.
The jumper was one of three men who leaped from the top of the 25-storey building on Adelaide Terrace about 2:00am.
