US diplomats say nearly a billion US dollars and eight years of effort by Australia has failed to bring stability to Solomon Islands.
The Sydney Morning Herald says the information was contained in assessments from the US Embassy in Port Moresby leaked to the whistleblower website Wikileaks.
The paper says the reports go onto say Australia's intensive policing and aid effort has not succeeded in stabilising the country.
The cables also say that Solomon Islands would relapse into turmoil within weeks, if the Regional Assistance Mission withdraws.
RAMSI comprising of Australian, New Zealand and Pacific island military and police contingents were deployed to the Solomon's in 2003 at the request of the government after a breakdown of law and order.
The leaked information describes Solomon Islands as "fragile" if not "broken" and that external assistance may be required for another 10 or 15 years.
However, the reports come as RAMSI announces the withdrawl of its officers from provincial posts.
The Deputy Commissioner of Police, Edward Sikua, has confirmed the first such draw down is to take place at the Buala Police Post on Isabel Island.
Commissioner Sikua said that after assessments by both local and regional police- it was found that the local personnel were capable of doing their job in the province.
