Member for Bega Andrew Constance was concerned for the region following the COVID-19 outbreak in Victoria.
He said those in Victoria returning home to the Eurobodalla Shire and Bega Valley must self-isolate for two weeks.
"There's quite a few locals who go down there to visit friends and family," he said.
"When they come back, they need to self-isolate for 14-days.
"Don't go to the shops, or down to the pub, or in to work - you have to be aware of how dangerous this situation is."
If people did not isolate, and were potential carriers of COVID-19, Mr Constance said loved ones and the community would be at risk.
The moment you show flu-like symptoms, Mr Constance said "go and get tested".
"There are pop-up testing clinics and extended hours at hospitals - if you have any symptoms please go and get tested and stay home," he said.
... we can not afford a run of the virus in our regionBega MP Andrew Constance
"We have got to up our testing rates in the region. We can't turn a blind eye, no one is invincible."
Mr Constance said the outbreak arisen in Victoria, "could happen anywhere".
"We are all in this together and have to work together and unite in the same way we did with the bushfires," Mr Constance said.
"It's hard and going to be doubly hard for border communities - but we can not afford a run of the virus in our region. We have to do everything we can to protect everybody."
A Victorian teenager visiting Merimbula was reported positive for COVID-19 on Wednesday, June 8. The teenager and family were among 80 others at the Tathra Hotel at the weekend.
Mr Constance thanked businesses like the Tathra Hotel for having a COVID plan in place and acknowledged the importance.
He urged everyone not to become complacent and to continue following the government's health advice.
The Victorian border closed at midnight on Tuesday, July 7.
However, essential travel and freight is allowed with a permit, granted through the Service NSW website.
As Transport Minister for NSW, Mr Constance said there will be a "significant disruption to freight" as the new permit system bedded down.
He asked applicants to be patient when going through the permit process.
"The government is doing its level best to get the systems in place as quickly as possible for our freight companies," he said.
"Be mindful it is going to be a disruptive initial couple of days, but it will settle down."
