Papua New Guinea's chief of staff for the defence, Captain Tom Ur, says while an independent gun study would be useful, more needs to be done to crack down on gun running.
AusAID has given just over 27- thousand US dollars towards a survey of guns in PNG as part of a regional firearms audit.
The survey is to determine the number of pistols, machine guns, and other firearms in the country.
Captain Ur says although there is a ban on illegal weapons, they are still getting through.
"because of lack of resources, we're not able to contain those open borders that we have. And when you get firearms like AK47s, which its not in our inventory, that its definitely coming from somewhere outside."
Captain Ur says they need more resources to assist with surveillance, particularly from the air.
