A set of new rules has been announced for tour operators taking people along the Kokoda Track in Papua New Guinea.
Last week, a Queensland man was the third Australian to die on the track this year. Paul Bradfield, 38, died from a suspected heart attack during his sleep after completing the 96km trek.
The ABC reports the trekking industry in PNG is governed only by a voluntary code of conduct.
Now the Kokoda Track Authority has announced that operators will need a commercial licence to run tours in the area from next year.
KTA chief executive Rod Hillman says the licenses will cover matters things such as training requirements, first aid details, insurance and conditions for the porters.
The authority says the licences will be in place for the start of next year's trekking season in April.
