Yes, you do need Travel Insurance, it is very important. You are responsible to organise your own Travel/Medical insurance, which can be organised at your Travel Agent.
You will need coverage for medical evacuation; medical, theft, loss etc… speak to your Travel Agent about the inclusions. Travel Insurance MUST include Medical Evacuation (anywhere along the Kokoda Track) and medical expenses including hospital coverage in PNG and Australia. It can be a very costly experience for you if you do not have your Travel Insurance!
We require a copy of your personal, Travel and Medical Insurance no later than 4 weeks before departure. Failure to have travel and medical insurance will prevent you from trekking.
