A man has been seriously injured after a twin cab ute landed on top of him as he was sweeping his front porch in Stanwell Park on Wednesday morning.
The white utility vehicle crashed into a power pole after coming unstuck near the corner of Lawrence Hargrave Drive and Railway Crescent just after 8.30am.
It then ploughed through a fence and hit the occupant of a home on Railway Crescent.
According to first reports from paramedics on scene, the driver was trapped by confinement and the resident - a man aged 57- had decreased consciousness, as well as chest, head and leg injuries.
The resident was in a critical state and went into cardiac arrest, but was able to be revived.
NSW Amulance Special Operations Paramedic Mark Bartlett was on scene and said it was "quite horrific".
"We had a lot of help from the community and other emergency services," he said.
"It was good to see the community band together in such difficult circumstances."
A rescue helicopter was sent from Bankstown and landed at the northern end of Stanwell Park beach, before flying the patient to St George Hospital with serious injuries.
The man, who is a carer for his elderly mother, was standing out the front of their house when the accident happened, according to his brother.
Their mother was "okay but shaken up", he said.
A nearby resident said she'd heard a loud bang and came out to see what was going on and could hear the victim's dog Simba crying.
Police from Wollongong and Sutherland Shire were in attendance and established a crime scene.
The driver of the ute was taken to hospital for mandatory testing, but suffered no known injuries.
Paramedics, Fire and Rescue NSW crews and electricity services also attended the scene.
Despite initial reports that a bus was involved in the crash, the NSW Transport Management Centre has now confirmed that the bus had just pulled over to the side of the road.
It's reported the driver stopped to try and assist at the crash scene.
