He described it as a lonely time where he felt he was there with fellow contestant Barb Raos just to "make up the numbers".
"We were locked out and that was because we were at different stages compared to the other contestants who were all aged between 20 and 30. At this point I was just waiting for the axe to fall."
Mr Davis battled on and found ways to cope with living off the bare minimum and being away from his family.
"I thought food was going to be a big thing for me but I learnt to chew 40 times a mouthful and if others struggled I wouldn't let it bother me."
What did bother Mr Davis was not being able to contact his wife and children.
"I just missed the little things, putting the kids to bed, making a cup of tea and hearing my wedding ring clink when I held a cup. The first thing I did when I was eliminated was put my wedding ring back on."
Mr Davis spent just over a month on the island before he met his fate and was voted off by the final three Tom, Avi and Barb.
"I had been dreading one challenge that had I seen on other seasons and when I came out of the jungle and saw that challenge I knew it was time for me to pack my bags."
Contestants had to use balance, which Mr Davis said was something he couldn't do.
"I am big unit and balance is not my thing."
Mr Davis said he learned a lot from the show and appreciated all the little things in life a lot more.
"It was my first night home and I said to the wife we better start cooking tea while its still light and she looked at me like 'are you for real? We do have lights'."
"You don't realise how greedy you are until you live off the bare minimum for a while. I don't need seven pairs of jeans or four different sauces on my burger."
Mr Davis said you can have very little and still be very happy.
"I'd hate to think how much time I spent just watching wood burn happily."
He recommended the experience to others and said he would do it all over again in a heartbeat if he had the chance.
