“It’s a bit like Malaria, it gets in your blood,” said Mr Davis.

“It’s much more than a walk, it’s the Gallipoli of WWII.”

Sharing our involvement in war is important to Mr Davis, a private pilot who worked at a mining service company in Orange and is currently in his eighth year of post graduate military history studies with the Australian Defense Force Academy.

“We try to give hikers an idea of what it was like but of course we have it a lot easier,” he said.

“No food, no medicine, being shot at along the track – it’s my passion sharing what the diggers did for us.”

Several thousand people walk the 96 kilometres every year.

Of the 559 Kokoda adventurers Mr Davis has lead only three haven’t finished.

“Being a trek leader is about encouraging people to access that 90 per cent of inner strength they need to keep going,” said Mr Davis.

“PNG is known as the land of the unexpected and Kokoda is known as one of the hardest tracks in the world.

“There’s a four kilometre swamp in one spot which means mud up to your boots – it’s tropical rainforest but it’s below five degrees at night.”

Mr Davis doesn’t believe any Orange trekkers are a risk of becoming the fourth evacuee.
