Victorian holidaymakers in the Eurobodalla Shire have packed up and raced home before the border closed at 11.59pm on Friday, January 1.
Some families only arrived in the area on New Year's Eve morning before they left that afternoon.
BIG4 Moruya Heads Easts Dolphin Beach Holiday Park executive manager Corinne East said there was a mass exodus, with some guests departing at 10.30pm on Thursday night.
Ms East hated to think of the danger drivers were in on the roads for so long.
Some guests had driven up in the morning only to pack up their elaborate set-up and drive down the same day.
A huge number of Victorians, due to arrive from January 2 throughout the summer holidays, have all cancelled their bookings.
Ms East said it was very upsetting evacuating the holiday park two years in a row.
"It's very distressing to lose two summers," she said.
She was hopeful others would keep their bookings, after only three new COVID-19 cases were reported in NSW on Friday.
"We are very fortunate we have a lot of people from the ACT and NSW," she said.
"We've had some people who called excited we have availabilities and can come visit us."
Batemans Bay Marina Resort general manager Andrea Giri said the resort was "lucky we don't have a huge amount of Victorian bookings, (but it's) enough to hurt".
Corrigans Cove Resort in Batemans Bay offered last-minute deals after cancellations left the resort with unexpected vacancies.
Half of BIG4 Ingenia Holidays Broulee bookings were cancelled on New Year's Eve however many bookings were filled by the following Monday, January 4.
Many of the Victorian guests were upset and stressed while packing up, park manager Tess Clark said.
She had become accustomed to fluctuations in bookings with COVID-19 restrictions, floods and fire.
Last year, she evacuated the park after a firestorm nearly took out Broulee.
This year's evacuation was a more "organised departure".
"This year felt like déjà vu," Ms Clark said.
She felt lucky those cancelling were regular visitors who would likely return throughout the year and the following summer.
Broulee's beaches were renown for surfing, she said, so most vacancies had already been filled by Monday.
Visitors from the ACT and all over NSW, particularly the Riverina area this year, were booked in.
"It's also a way to get new guests coming into the park who might come another time during the year," she said.
