Papua New Guinea's internal security minister says the country's relationship with Australia makes it more vulnerable to a possible terrorist attack.
Bire Kimisopa was commenting after the car bomb attack outside the Australian embassy in Indonesia and after the Australian high commission said PNG was perceived to be a weak link.
Mr Kimisopa told the National newspaper that PNG stands as a soft target for terrorist organisations who want to use it as a launch pad for a strike on Australia.
He says as a result of a historical relationship, there are more than 10,000 Australians in PNG.
He says the fight against terrorism requires developed countries to share information and he expressed hope that the new co-operation programme would improve PNG's guard against such crimes.
