Griffith's Local Health Advisory Committee is leading the charge for people to get themselves tested.
The city has been free of the virus for over 40 days, however LHAC chairwoman Margaret King said now that restrictions were being lifted, testing was important.
"Now that we can travel interstate (from June 1) and the schools have re-opened, getting tested has never been more important than now," Mrs King said.
"One case can have a devastating impact."
The testing rates are relatively low across Murrumbidgee Local Health District with only 8806 people tested by 8am on Sunday.
In April, NSW Premier Gladys Berejiklian said she wanted to see 8000 people tested a day.
Anyone not feeling well or displaying the symptoms of fever, sore throat, a cough or short of breath is urged to get tested.
Mrs King said the biggest worry going forward was not worrying about COVID-19.
"Complacency and becoming blase about the risks is the biggest concern," she said.
"Now that things are starting to open up, nobody wants to have to go backwards.
"Now that we're heading into the winter 'flu season, the worry is people will write off the sniffles or a cough as a head cold when it could be something else."
Mrs King praised Griffith for the uptake of the influenza vaccine, with demand this year doubling over last year according to some pharmacies.
"We've been really happy with the uptake of 'flu shots right across the Murrumbidgee," she said.
"But it won't protect you from COVID-19, if you do get COVID, it won't be as bad, but it will only protect you from the 'flu."
Mrs King said Griffith was spoiled for choice when it came to places to get the COVID-19 test, with a public clinic and a private clinic.
"I've done the test, they ask you some questions, they make the appointment and you go straight in. Then you have to self-isolate and wait for the results which come through on your phone in under 48 hours," she said.
"Testing doesn't indicate immunity and if you get the symptoms again you need to get tested again."
MLHD's mobile testing clinic will visit Leeton on Thursday and Darlington Point and Whitton on Saturday.
Appointments can be booked by calling the MLHD COVID-19 hotline on 1800 831 099.
