BRIBIE Island resident Denis Nicol and his wife are still living in fear after they were assaulted one night in July last year.
Mr Nicol, 71, was attending to his wife Lynette's asthma attack when the attacker trespassed into their front yard and punched him in the face.
The 57-year-old man pleaded guilty to assault occasioning bodily harm in the Brisbane District Court last Thursday.
He was ordered to pay compensation to Mr Nicol and received a sentence of four months imprisonment, suspended for 12 months, and had a conviction recorded.
Justice has been served, according to the courts, but Mr and Mrs Nicol are still suffering physical and psychological damage.
"I am on sleeping tablets to help me sleep, and my wife is having nightmares that this fellow will return and re-offend," he said.
"Our previous leisure time is now taken up with ongoing doctors' appointments, both on the island and in Brisbane."
Mr Nicol was a secretary of the Bribie Island Vietnam Veterans Association for six years, and has led 45 treks to Kokoda as well as raised money for the Leukaemia Foundation by reaching Everest Base Camp and the summit of Mt Kilimanjaro.
As a Justice of the Peace, Mr Nicol will now only witness papers away from home, with frequent doorknocking causing him and his wife further anxiety.
"We have gone from being active people in the community to being stay-at-home people locked behind closed doors," Mr Nicol said.
They have been residents in their Bribie home for more than 50 years, but have had the house up for sale since the incident in the hope of moving closer to their daughter's home.
A neighbour of 85 years of age has already moved out due to the assault.
Mr Nicol is hoping more people in the community are aware that one punch can kill.
The Queensland Police Service is now heavily campaigning the One Punch Can Kill slogan with decals positioned on all marked police cars in the state.
