Sergeant Day is one of 60 officers from police, fire, ambulance and police legatees who will spend eight days confronting the arduous Kokoda Track, as part of the 2015 NSW Police Legacy Kokoda Trek.

The annual trek is in its 10th year and will depart this month to pay respects to those famous Diggers who fought along the Kokoda Track to save Australia from invasion in 1942.

Sergeant Day will join Detective Senior Sergeant Darren Kelly of the Wollongong Command to represent the Illawarra in completing this year's NSW Police Legacy Kokoda Trek.

Sergeant Day said he was excited and daunted by the task ahead.

"It's going to be a challenge," he said.

"With the combination of difficult terrain, heat and mosquitoes it is going to be hard, but it's obviously interesting at the same time."

The Kokoda Track is 96 kilometres and takes eight days to complete.

The track passes through rugged mountain ranges, steep valleys and jungle.

This incredible environment is also home to the most beautiful people who are very welcoming.

"It is certainly a difficult path, over eight days with no rest time, in another country, away from the comforts of home, but it's a life achievement.

"It's an important year being 100 years for Anzac and obviously a worthy cause being a police legacy."

Sergeant Day said the group hailed from different backgrounds and age groups and had been training both together and individually.
