The border between NSW and Victoria will be closed as of 11.59pm on Tuesday night, but travel within NSW, and to other states is still permitted.

The NSW government has no limitations on travelling to NSW for a holiday.

Under the current guidelines, up to 20 people may stay in a holiday home or rental. More are allowed if they are all members of the same household.

Anyone visiting a national park camping ground must book ahead.

However, while travelling is permitted, anyone with COVID-19 symptoms, such as a sore throat or respiratory issues, needs to get tested. Isolating is required while waiting for the test results.

Practicing good hygiene and maintaining physical distancing is also important.

Gay Stewart is among those who say they will be travelling.

"Already started! Life has to go on...," she said on the Daily Liberal Facebook page.

"Thoroughly enjoying the happiness of caravan park owners on reopening, not to mention shops, pubs and clubs that have had it so tough for so long."

Meanwhile, Tanya Crowe said she was staying at home.

"Nope still paranoid. If the town is going to be flooded with tourists I'll be getting my groceries home delivered," she said.

Others expressed shock at the number of travellers they had already seen on the roads.

"I travelled from Gilgandra to Dubbo today to do my food shopping and the amount of caravans on the road from Victoria was terrible," Karlie Jones said.

The rules for visitors coming to your house are similar.

Up to 20 people, adults and children, are allowed to visit at one time. They are also permitted to stay overnight.

However, the NSW government recommends that anyone over the age of 70, or those who have a pre-existing medial condition, should be cautious and limit the number of people they have visiting.

The Public Health Act 2010 (NSW) provides police with the power to enforce the COVID-19 related ministerial directions.

It is an offence for a person to fail to comply with an order, and severe penalties apply, which can include a maximum penalty of up to $11,000 and/or six months imprisonment for individuals.
