Although there was no loss of life from enemy attacks while they were in Borneo, the friends say it was very tough patrolling the jungle and they lost two friends who drowned while crossing a river; and their friend Paul Denehey, who was attacked by a rogue elephant and died from his wounds as the troops were far from medical help.
"I remember the sound of the elephant screaming after it had so many bullets fired in to it and it took a long time to die," said Mr McDonald.
Mr Berge said he crossed the ditch as a young man after working with two Australians on a shearing gang in Hunterville.
"They told me there were good jobs there and I found work on a farm in Kalgoorlie in Western Australia but I was only getting bed and board so I joined the army."
Mr Berge left the army after serving in Borneo while Mr McDonald went on to serve in the Vietnam war.
Returning to Whanganui Mr Berge met his future wife Pat from Maxwell at the Wanganui RSA and settled in Aramoho.
"In all the years I have known Rodney, I've never heard him raise his voice," said Mr McDonald of his old friend.
Mr Burge said he lets off steam with a bit of hunting and fishing and likes to get out on his own sometimes.
"When I'm out in the bush, I give myself a bit of a tune-up," he said.
Back in Mandurah Mr McDonald is a Justice of the Peace and mentors troubled teenagers.
The friends will attend the Anzac dawn service in Whanganui on Monday before attending the later service at Maxwell.
