Some group sizes are getting near to 150 people, and when 2 groups of this size meet in a village it strains resources. There are new tracks being cut to just take the new numbers and new camp sites cut into the jungle for such large groups. Rubbish disposal alone is a problem - in theory it is 'carry in, carry out' but sometimes it is buried and then dug up by dogs. Big lines of trekkers frequently stretch for several kilometres along the track. One wonders how trekkers can get the true 'Kokoda Experience' when group numbers start to resemble a travelling circus.

It would be wise for those contemplating a trekking company to enquire closely about numbers - my preference would be for small groups with total size limited to 30 or so.

In addition, with so many more trekkers , there are more trekking companies operating now, and some of these leave a bit to be desired. The radio system in villages along the track is not reliable, and carrying a satellite phone is a must for any group. There also must be a reliable base, back in civilization. Unfortunately many local companies just do not have the capital or organization to provide that level of security. Great guys, really strong and willing and keen to please, but without much backup. Be careful.
