Australian women from two families are among a group of resort guests fighting for life after a suspected mass alcohol poisoning on Fiji’s Coral Coast.

Seven people fell seriously ill after drinking cocktails at a pool bar in the five-star Warwick Resort on Saturday night, local media reported.

They included four female Australian tourists, an American tourist and two foreigners who live in Fiji.

The victims were rushed to Sigatoka Hospital with “nausea, vomiting, and neurological symptoms”, Fijivillage.com reported.

They were all later transferred to Lautoka Hospital because of the severity of the symptoms.

The victims are reportedly aged between 18 and 56.

The ABC said two of the Australians were critical, with a 56-year-old woman under constant surveillance in hospital and a 19-year-old woman experiencing serious medical episodes.

Two other Australian women — a 49-year-old and an 18-year-old — were still critical, but not as serious, reported the ABC.

Police and health officials are investigating the incident as alleged alcohol poisoning.

Fiji’s health ministry said a team of inspectors had been mobilised to investigate the incident and identify other potential victims who consumed the same drink.

The government has reportedly ruled out Covid and other common illnesses that affect tourist spots.

The Department of Foreign Affairs and Trade said on Sunday it was providing consular assistance to two Australian families in Fiji.

“Owing to our privacy obligations we are unable to provide further comment,” a spokesperson said.

The department revised its travel advice for Fiji on Sunday following the incident.

“We continue to advise exercise normal safety precautions,” the Smart Traveller advice for Fiji said.

“Be alert to the potential risks around drink spiking and methanol poisoning through consuming alcoholic drinks.

“Get urgent medical help if you suspect drink spiking.”

Warwick Resort is an all-inclusive family beach resort on the Coral Coast which stretches between Sigatoka and Suva on Viti Levu island.

The incident in Fiji follows a mass poisoning that killed at least six tourists in Laos including two Australians.

Nineteen-year-old Melbourne friends Bianca Jones and Holly Bowles died in Thai hospitals in November of suspected methanol poisoning after drinking tainted alcohol in Laos.
