Staff have defended Mogo Wildlife Park (formerly Mogo Zoo) from the fires, but remain on alert in case of another flare up.
The park's director of life sciences Chad Staples told the ABC no animals had been lost.
"A couple of hours ago it felt like Armageddon here. It was as black as midnight, with tinges of red. It was like we were fighting fires in the darkness. Right now, we feel that we've got a reprieve" he said.
"Thankfully prayers were answered and the wind changed. Then we were able to get on top of it. Now we're just very much in a state of readiness, I guess. We're making sure that nothing flares up - or nothing comes from a different direction now that the wind's changed."
The fire is threatening South Coast communities between Batemans Bay and Broulee.
A spokeswoman for the Mogo Wildlife Park said a number of staff were at the site, including Mr Staples, who is coordinating the operation.
She said staff were watering everything down and doing everything they could to protect the animals.
There are about 200 animals at Mogo Wildlife Park and all of them were on site. The fire had spread much more quickly than expected on Monday night and it had not been feasible to evacuate the animals.
The spokeswoman said the animals' reaction to the smoke and fire conditions would vary from species to species.
Staff had moved the animals into a safe and comfortable place within the park.
"That would be their first focus. We always put the animals first," she said.
Featherdale Sydney Wildlife Park took over operation of the Mogo Zoo in November.
The park houses African lion, cheetah, zebra, multiple primates, rhino and recently welcomed some tiger cubs.
NSW RFS Commissioner Shane Fitzsimmons highlighted Mogo as an area that was at risk of experiencing increasingly volatile fire conditions as the weather changes.
