Tonga goes into lockdown as 2 wharf workers test positive for COVID-19

The delivery of aid would not change as a result of the COVID-19 cases, he said, adding, “frontliners will need to be more careful”.

The Australian Defence Force’s Chief of Joint Operations Greg Bilton said it did not appear the HMAS Adelaide was the source and samples from the two wharf workers would be sent to Australia for testing to verify the origin of the COVID-19 strain.

“I don’t think there’s any connection, there’s no evidence of that,” he told Sky News.

Tongan radio station BroadcomFM reported on Wednesday another three cases had been detected in a family, bringing total case numbers to five.

Tongans queued at shops and banks on Wednesday ahead of a lockdown to start at 6pm, as authorities attempt to stop the spread of COVID-19.

Health authorities were administering booster shots to the public on Wednesday, with more vaccine booster doses to arrive from Australia and New Zealand. Around 83 per cent of the eligible population have received two doses of vaccine.

In addition to HMAS Adelaide, three New Zealand and one British naval ships, and two Chinese fishing ships from Fiji have come into port and unloaded aid pallets. French, Japanese and Chinese navy ships are also en route carrying aid.

The Tongan government has insisted on contactless delivery of aid, and all pallets unloaded from aircraft or ships are isolated for 72 hours before being distributed by the local emergency service.

At a press conference on Tuesday, Tongan authorities said the two workers at Queen Salote wharf who tested positive were vaccinated, and it was unknown if they had the Omicron variant.
