Preparations are underway on an Indonesia-Papua New Guinea border post where the Prime Minister, Sir Michael Somare, and the Indonesian President, Susilo Bambang Yudhoyono, will open a new highway.
The two leaders are to meet next Wednesday to open the highway.
But a PNG official from the Department of the Prime Minister says the the opening has been deferred indefinitely.
A recent visit to the border by the PNG Defence Force commander, Commodore Peter Ilau, uncovered a lapse in security.
Meanwhile, a former commander, Major-General Jerry Singirok, says Indonesian terrorists have an open door into PNG to target Australians and their mining and energy interests thanks to Canberra's push to slash the size of PNG's military.
