Manus Governor Charlie Benjamin slams Australia over plans to redevelop a joint naval base on the Pacific island, saying he's never been consulted on the plan that the United States is also backing.

Manus Governor Charlie Benjamin told the ABC's Pacific Beat program that the deal to redevelop the Lombrum naval base was unnecessary and that he does not believe the base serves the interests of locals.

"To be honest PNG is not at war and we do not need any help right now, simply by coming to Lombrum is accommodating the interests of Australia and America," Mr Benjamin told Pacific Beat.

His comments echo those of others from Manus who are critical of the deal, including former MP Ronnie Knight, who told Pacific Beat earlier this month the plan was "bulldozed through" without local consultation.

During the APEC summit US Vice-President Mike Pence said the US would also be involved in the project, with PNG Prime Minister Peter O'Neill thanking the US for their support.

the Opposition is already considering pursuing legal avenues against the plan, due to the lack of government consultation with the local community.
