The Papua New Guinea police commissioner, Tom Kulunga, says the Australian Federal Police now working alongside his officers are vitally needed.
300 officers began working in Port Moresby and Lae last week and another 20 are coming next month.
Mr Kulunga says the PNG constabulary, until the last two years, had not recruited new staff, leaving the force depleted and old.
Mr Kulunga says there is a real need for help in the administration of the police stations around the two cities and this is where the advisors will fit in.
He says they will complement the shift supervisors in the suburban stations.
"Some of the roles would be to help us with mentoring and to be able to help us with preparation of quality court files, and at the investigation level, with the fraud squad, because we understand that they have a very high standard of fraud investigators"
