His total service in WWII was 1478 days of which 932 days were served outside Australia.
He said he was surprised when he found out he was to be awarded an OAM.
"My reaction was why me?" he said.
"But there must be something that stands out over [my] lifetime to be brought to their attention.
"Somebody's looking after me."
Mr Walker said as vice-president of the Rats of Tobruk Association he helped look after his "mates because some of them were doing it a bit tough".
He has also had a lifelong love of horses.
