The new mobile service will be available on Thursday, May 14, from 10am to 3pm.

The health district's executive director of Aboriginal health and wellbeing, Brendon Cutmore, said Oberon was selected as a testing site as one of the most eastern towns in the district.

"It's closer to Sydney and possibly at more risk of being a destination for people leaving the city for a bit of a break," Mr Cutmore said.

"COVID-19 tests are always available through GPs and our hospitals. Our plan is for the mobile service to visit a number of smaller communities, starting with Oberon, to provide an additional opportunity for testing.

"The testing service will be set up in the Robert Hooper Community Centre carpark at 13 Tallys Lane. To help manage traffic, we're asking people to enter from Fleming Street and exit on Ross Street.

"The service is free of charge, and you don't need a referral or appointment to attend."

Mr Cutmore said people would not need to leave their car to be tested.

"Our staff will be able to come to you, do a short assessment and get your details, and then do a swab from the back of your throat and then the back of your nose," he said.

"The tests are then sent away for analysis which normally takes about 48 hours. If your test is negative, you can request to get those results by text message even faster.

"People who are tested are asked to self-isolate until they get their results."

Mr Cutmore said the symptoms of COVID-19 could be very mild so it was important for the state to increase its rate of testing to identify more cases.

"While most people who have COVID-19 will recover, some people can become very sick, particularly older people or people who are already ill," he said.

As of Tuesday, there had been 112 tests in Oberon, with no cases found.
