The good news is, within the past 14, none of his close contacts have tested positive.

The person flew before they themselves knew they were a close contact of a case in Sydney.

At the time following the December 21 flight and December 24 diagnosis of the man, a public health alert was issued while the NSW Health contact tracing team worked with the airline to identify and contact the passengers and crew.

Four other close contacts of the person were also identified.

All close contacts returned negative tests for COVID-19 and remained in self-isolation until 14 days after their exposure.

Murrumbidgee Local Health District's director public health Tracey Oakman said close contacts are released from isolation after 14 days if they are well.

"I wish to thank these people," she said.

"They have co-operated fully with the testing and isolation requirements that were asked of them.

"We acknowledge the tremendous impact this has had on contacts and their families over the Christmas period.

"I would also like to thank the community for supporting their fellow residents through this time."

MLHD's Griffith testing clinic moved from the Hospital to Yambil Street before Christmas in order to provide a more central and accessible option for testing.

Since its move, the clinic has seen consistently higher numbers of people seeking testing.

To arrange a test at any time call the Murrumbidgee COVID-19 Hotline (8am-6pm) on 1800 831 099.
