Fiji's former deputy director of public prosecutions, Peter Ridgway, says he's considering returning from Australia to continue his anti-corruption work in Suva.
The interim Prime Minister, Commodore Frank Bainimarama, says he's keen to secure the services of the Australian, to examine corruption allegations against the ousted Qarase government.
Mr Ridgway was expelled from Fiji 18 months ago while investigating links between the government and the 2000 coup.
In an interview with the ABC, he indicated he would consider returning to finish the job.
"The task of dealing with corruption not just in Fiji, but in the Pacific generally, is an incredibly important one. I think so many of those economies are held hostage to corrupt conduct and governments seem to be either singularly unable or unwilling to tackle it. It's a very high priority for me."
He says running an anti-corruption campaign with an interim administration in place will be difficult, and the best option is to use existing police powers.
