Scaffolding has collapsed at a worksite in Perth's south during unusual weather, injuring at least six people.
The Department of Fire and Emergency Services received a call shortly after 2:00pm when a water spout crossed the coastline in North Coogee and hit the site on Orsino Boulevard.
Contractors from Legend Contracting were working above and below the three-metre scaffolding at the time and suffered a range of injuries.
A St John Ambulance spokesman says several crews were sent to the site. The rescue helicopter was also sent to assist.
Four people were taken to Fremantle Hospital, and another two were taken to Royal Perth Hospital with more serious injuries.
Authorities say there will be an investigation into why the scaffolding collapsed.
Department of Fire and Emergency spokesman Tony Nicholas says a number of groups are reviewing the incident.
"The Bureau of Metereology is here on site. They will be conducting some investigations," he said.
"We have wind speed specialists and they'll be working with WorkSafe to try and prevent this happening in the future."
