The armed guard bashed with a hammer while patrolling Victoria's Parliament House is philosophical about his ordeal and eager to get back to the job he loves.
"That's life," James Vongvixay said when asked how he felt about the attack on December 11 last year.
"I love to go to work.
"When I'm fit and I'm ready to go to work then I'll do that."
Mr Vongvixay, a Protective Services Officer (PSO) for seven years, left the Epworth Rehabilitation hospital on Friday.
The lines of stitches still visible on the top of his scalp are clear evidence of the brutality of the attack, which left him with a fractured skull and bleeding on the brain.
He walked from hospital with his wife, Karen, and adult children, son Chris and daughter Noi Terlato.
There was an outpouring of sympathy for Mr Vongvixay after the attack and he thanked all Victorians for their support and concern as he recovered.
Ms Terlato said while her dad was able to spend a bit of time out of hospital over Christmas, they would have many celebrations at home.
Asked if the family was happy for him to return to work, she said: "He doesn't like to be idle, so he's always on the go, so he'll be very happy to at least keep himself moving."
Professor John Olver, Director of Rehabilitation at the Epworth, said Mr Vongvixay had suffered some weakness in his right arm and problems with fatigue and concentration due to the bleeding on the brain.
"Yes, it could have been worse but he's been fortunate that he's recovered quickly," he told reporters.
"There sometimes can be a bit more fatigue in the longer term than there was before but it looks as though he'll make a very good recovery."
Prof Olver said Mr Vongvixay could return to work in six to 12 weeks, part time.
The man who attacked Mr Vongvixay with a hammer fled with the armed guard's gun, before fatally shooting himself in parkland about 800 metres away.
The first hearing for a pending coronial inquest is due to be held next week.
