Hancock offered to reduce the morning hour the helipad could be used from 7am to 9am and change the flight path to ensure the helicopter followed existing busy roads, but the company rejected concerns about noise from the chopper, saying its own study suggested nearby main roads were noisier than the Bell 429.
“The immediate locality is already subject to the background noise of Thomas Street and Kings Park Road (very busy roads) 24/7, and noise from bin trucks, ambulances, police, fire engines and freight trucks etc, which operate in the early morning or evening (and not just daylight hours as is being proposed),” the company said.
“The noise level from our proposed helicopter (Bell 429) movement is 92dB in comparison to 106dB recorded maximum noise levels in the area already due to local traffic.”
Hancock also argued the helicopter would only generate noise at the site for two hours a year – roughly 10 minutes per landing and take-off.
The company also revealed it had been speaking to emergency services bodies to discuss the potential for them to use the helipad.
“With the building’s location right between Perth’s two major trauma hospitals, and the Perth Children’s Hospital, the helipad would provide a life-saving potential as it has the ability to serve as a crucial backup landing option for emergency services (such as Department of Fire and Emergency Services and police) and the Royal Flying Doctor Service,” it said.

“They have advised that they are often faced with scenarios where they cannot land at existing facilities and so any additional options could help save lives.”
City of Perth councillors will vote on the recommendation at their council meeting next week.
Hancock’s new headquarters were approved by the city in 2023 and construction is already under way.
It’s not the first time a West Australian mining billionaire’s helicopter has caused a stir among locals.
Last year, this masthead revealed Mineral Resources boss Chris Ellison’s use of a helicopter to commute to the company’s Osborne Park headquarters had raised the ire of nearby land users, and led to questions about who, exactly, had given the green light for the chopper to land opposite a wildlife sanctuary.
