Kangaroo Valley resident Peter Botsman has been waiting since December 30 for the results of his COVID-19 PCR test.

Mr Botsman said he had been isolating after suffering from COVID-19 symptoms but was still waiting a result.

"I was pretty sick. I had all the symptoms and now I'm almost out the other side," he said.

"There were about 60 or 70 cars lined up. They said 72-hours [for the result] so for the first three days I just let it go but now it's up to more than 150 hours.

"And there's no way of calling them [the pathology services] either."

Now Mr Botsman faces another dilemma with needing a second PCR test and negative result before he can visit his family in Queensland.

Many local residents across the region left waiting for their results have taken to social media to complain about the delays.

The delays come as NSW recorded more than 20,000 fresh infections in the 24-hour period to 8pm on Monday, January 3.

While the Illawarra Shoalhaven local health district has added another 525 COVID-19 cases.

Meanwhile, there is a shortage in supply of rapid antigen tests across NSW including Shoalhaven, with pharmacies reporting they are unsure when their next order of kits will arrive.

Earlier this week, Shoalhaven leaders rallied to call out Prime Minister Scott Morrison for refusing to make rapid antigen tests free.

Unions Shoalhaven slammed Mr Morrison over the decision, claiming it is essential the region's workers and vulnerable people have access to them.

"The most vulnerable in our society and the people who need to have it for their work situations, should have access to the free rapid antigen tests," secretary of Unions Shoalhaven Pat David said on Monday.

"People who are living below the poverty line and who can't afford them won't be able to access them, they won't be testing themselves."
