A building has collapsed in Sydney’s inner-city suburb of Ultimo, injuring multiple people and sparking a major emergency response.

Part of a wall collapsed near a Shell service station on Wattle Street shortly before 11am on Monday, trapping several workers beneath the rubble. 

Debris had also crashed into vehicles parked nearby the service station.  

NSW Ambulance told Daily Mail a man in his 60s was taken to Royal Prince Alfred Hospital and a man in his 30s was transported to St Vincent’s Hospital, both in a serious condition, while five others were assessed at the scene.

A bystander said he had been parked beneath the wall just minutes before it collapsed. 

‘I heard a lot of not normal noise, so I moved my scooter and two minutes later, the wall fell,’ he said. 

‘I was shocked and surprised.  

‘I feel lucky, but I hope the people who are injured will be safe.’

Footage shows two paramedics talking to a man in blue, who appears to be a tradie, sitting down on the kerb with a towel around his neck, before leading him into an ambulance.

A NSW fire department spokesman said the service station was shut down and ‘the buildings around have been evacuated’.
