Papua New Guinea police are investigating allegations a brutal attack on an Australian aid worker is linked to his work exposing corruption.
A spate of car-jackings in Port Moresby has given rise to a climate of fear among some Australian officials, so much so Australia's High Commissioner to PNG, Ian Kemish, has met police chiefs to discuss his concerns.
One of these incidents included a male aid adviser working in PNG's National Aids Council Secretariat who suffered serious injuries in an attack last month during a car-jacking that required him to be flown to Brisbane for treatment.
The AAP news agency reports that another Australian adviser with the Secretariat ended her contract shortly after her colleague's car-jacking.
She had suffered repeated violent threats.
