The founder of the feared Comanchero Motorcycle Club, who was sentenced to life in prison for his role in the infamous 'Milperra Massacre', maintains he 'hasn't changed' despite creating a new life as a community-minded firefighter.

Jock Ross, a 76-year-old grandfather of 12, was president of the notorious bikie club in the 1970s and 80s in Sydney.

But the Scottish immigrant has since created a new life in Spencer, north of Sydney, where he serves as the captain of the New South Wales Rural Fire Station.

Despite turning over a new leaf, Ross doesn't look back on his time leading the bikie group as a bad memory but rather 'another chapter' of his life, A Current Affair reported.

Ross was in power of the Comancheros when members broke away to form the Bandidos, another motorcycle club who quickly became a deadly rival.

He spent more than five years behind bars following the bloody Milperra Massacre on Father's Day in 1984 in which seven people were killed.

Ross suffered wounds to his head, neck, chest and face when the two motorcycle clubs - the Comanchero and newly formed local chapter of the Bandidos - staged a shootout in the carpark of a tavern in southwestern Sydney.

He was sentenced to life in prison but was released in 1992.

Ross still regretted the events of the day, when he lost a lot of 'good mates'.

Though his time in the bikie gang was marred by violence, Ross maintained that his leadership was about a lifestyle, comparable to a tight-knit family.

'It was the lifestyle at the time… it were (sic) a family at the time… that's what we were when I was running it. It was a family ... so that's it,' he said.

After his stint in jail, Ross and his wife of 49 years, Vanessa, moved to Wiseman's Ferry in late 1993.

The area was hit by fires in January and Ross decided he wanted to help fight the blazes - and he's been firefighting ever since.

Mrs Ross, the Spencer Rural Fire Service call out officer, said her husband has been the same the whole time they've been together.

Ross was asked by A Current Affair if he was proud of his community work and whether he would have had the same attitude to help people back in the 80s.

He said: 'Yes, I would have. I haven't changed, I'm the same person from there to here.'

A few weeks ago Ross and his fire crew made headlines for their heroic efforts to pull a man and his dog from a burning house.

Ross, who was on call with Spencer's deputy captain Alison Wade, used quick-thinking to smash the door with his shoulder and enter the property.

The duo were able to drag the man from his bedroom, an escape that Ross believes wouldn't have been possible without their efforts.

RFS fire controller Viki Campbell commended the team for their efforts, the Daily Telegraph reported.

'As far as the brigade goes, it's quite a good brigade and they do quite a good job protecting their community,' Ms Campbell said.

'To get there in time to get the man and his dog out, they've done a good job.'
