While finishing up his lunch break, Mr Dillon noticed a woman slumped over in her car on Wellington Street and went to investigate.
�The car had rolled back and I could see something had happened to her,� he said.
�I asked if anyone around was a doctor or nurse but there was no one, so I got in the car next to her and started mouth-to-mouth.�
While a bystander rang emergency services, Mr Dillon continued to give the woman CPR to keep her alive.
An ambulance arrived about 20 minutes later and it was discovered the woman had suffered a heart attack. As it transpired, thanks to Mr Dillon, the woman, a nurse in her 40s, survived the incident.
�I was in contact with her since it happened, and it turned out she was pregnant,� Mr Dillon said.
�So I didn�t get to save one life, I got to save two.�
Mr Dillon�s heroic act was recognised recently in the 2015 Royal Life Saving Bravery Awards.
He attended the ceremony at the Government House Ballroom with his wife, two daughters, son-in-law and grandson.
�It�s been a journey, I felt so proud and humble to have won the award,� Mr Dillon said.
�I�m just so happy the woman is fine.
�She�s as good as gold and her pregnancy was all going well.�
