Fiji police are taking seriously a death threat made against Australian High Commissioner James Batley last night.
Police spokeswoman Ema Mua said their Special Branch had increased security around the Australian High Commission in Suva, as well as other foreign embassies and commissions in the country.
She said the threat was contained in a taxi-delivered letter handed to high commission security staff last night.
"At the moment, we are very much concerned about looking after the safety of the foreign workers. That is paramount," Mua said.
"We are taking this very, very seriously."
Although details of what was in the letter have not been released, Mua said the threat may have had political implications.
"We are getting this implication that perhaps people are trying to sabotage what government is trying to do and in the process doing these kind of things," she said.
Fiji has been ruled by military commander Frank Bainimarama since a bloodless coup in December 2006.
Australia has sanctions against Fiji and has been a staunch critic of Bainimarama's regime.
"I don't think it is people upset with Australians. I should think it would be some people trying to sabotage what our government is trying to do," Mua said.
A statement from the Australian High Commission said two copies of an anonymous threatening letter primarily directed at Batley were delivered early yesterday evening.
"The threat appears to be politically motivated by a person or persons who object to the Australian government's current policy on Fiji," it said.
"Needless to say, neither the high commission nor the Australian government will be intimidated by threats."
The commission gave thanks for the speedy response by Fijian police and assurances made by senior government officials.
Appropriate security arrangements had been made and the commission remained open for business, the statement said.
