Security is being tightened at Fiji's Nadi and Nausori International airports in preparation for the Rugby World Cup in Australia.
Radio Fiji says the security review follows an assessment of existing internal and extrernal threats.
Fiji will be one of the main transit points for Australia for those travelling to the World Cup.
In addition to concerns arising from Fiji's direct involvement in Iraq by reserve soldiers, security levels have been raised as a deterrent to possible terrorist activity.
Security levels on all flights to Australia from Nadi and Nausori airports have been upgraded to level three from today, the same as that applicable on northbound flights to the United States.
