A SWAN View grandfather critically hurt after trying to break up a fight outside his home says he'd do it again.

Terrence Cameron suffered bleeding on the brain when he stepped in to stop an alleged attack on a pregnant women on Buckingham Street a fortnight ago.

He was raced to hospital with a life-threatening skull fracture, which police said was inflicted when he tried to stop a fight between his neighbour and the neighbour’s pregnant girlfriend.

Speaking to Seven News from his hospital bed today, the 67-year-old said: “I feel pretty stuffed up”.

Detectives allege Mr Cameron was knocked unconscious after a single blow to the face and hit his head on the road as he fell backwards.

Mr Cameron can't remember anything about the alleged assault.

"I woke up in an ambulance and thought what the f*** happened," he said.

There were tense moments during the past 13 days and at times the grandfather's family feared he might not pull through, his son Colin Cameron said.

"I always was preparing for the worst, and there was a moment there and the prognosis wasn't very good, I'm glad he is here now," he said.

Royal Perth Hospital trauma specialist Dr Sudhakar Rao said Mr Cameron was lucky to be alive but he may never fully recover from his injuries.

"He has lost a certain amount of cognitive function, he's lost the ability to think things through," he said.

Premier Mark McGowan was so moved by Mr Cameron's selfless actions he visited him in hospital this week.

Even after all he's been through the retired truckie said he would not hesitate to step in again if he saw someone else needing help.

Mr Cameron was keen to get home but doctors expect he would remain in hospital for at least another two weeks.

"I'd love to get home, love to sit in the backyard with a little fridge and sip sip sip," he said.
