Airlines restore Fiji flights

Some airlines will resume flying in and out of Fiji after a tropical cyclone tore through the islands, leaving homes flattened and at least five people dead.

As the clean-up effort began after Cyclone Winston, the strongest cyclone on record to hit the Pacific islands, Virgin Australia, Fiji Airways and Air New Zealand said flights would resume on Monday.

Unrelenting rain and downed powerlines hampered relief efforts on Sunday as officials assess the damage.

Virgin updated its Monday flight details about 4.50pm on Sunday, giving relief to stranded tourists.

People whose flights were cancelled will be provided with updated flight details, Virgin said in a statement.

Fiji Airways advise passengers due to the destruction caused by the cyclone, some services out of Nadi on Monday may operate without its regular catering.

Air New Zealand cancelled flights in and out of Nadi on Sunday but said scheduled services would resume on Monday.

Jetstar's flights between Sydney and Fiji remained cancelled for Monday.

A decision on Jetstar's Tuesday flights will be made on Monday.

The devastating category-5 cyclone that swept over Fiji led the government impose a nationwide curfew.

Winston made landfall late on Saturday, delivering wind gusts of up to 325km/h.

Weatherwatch says the storm was the strongest on record to hit Fiji.

UNICEF worker Alice Clements - who is staying in Suva - described the beginning of the storm to AAP on Saturday night as a dystopian scene of downed banana trees, howling winds and the "ominous" sounds of corrugated iron lifting on some of the roofs.
