While the trappings of Christmas can still be seen among the camping area's charred remains, the sight of burnt and smouldering trees has become an unwelcome and all-too familiar part of Christmas in the Shoalhaven in recent years.

Again this Christmas was marred by the threat of fire, which last week forced evacuations in Jervis Bay village, and in Booderee's camping grounds at Green Patch, Caves Beach and Bristol Point.

The fire had been burning for several days before gusty winds on Monday whipped up the blaze and carried flames towards populated areas at Jervis Bay and surrounding regions.

Flames came right to the rear of residential properties before being stopped by fire fighters from the NPWS and Rural Fire Service.

Residents were evacuated to HMAS Creswell, as were about 100 people who were in camping grounds.

Park manager Scott Suridge said an accurate list had been kept of all campers, which enabled rangers to ensure all people were evacuated from the camping spots at least an hour before the fire front raced through.

"Some people lost their camping gear, but there were no injuries and no major losses," Mr Suridge said.

The three popular camping grounds will remain closed until at least January 10, with Mr Suridge saying park staff were working as quickly as possible to make the areas safe for visitors.

However many trees were unstable and dropping branches following the fire, he explained, and the park "has to remain closed while access and safety issues are being assessed".

Fortunately the animal death toll from the fires appears to be low, with Mr Suridge saying no burnt or injured kangaroos or wallabies had been found since the fire passed through.

However he expected a higher toll among ringtail and brushtail possums, sugar gliders and even bandicoots.

"Removal of the understorey will obviously have an impact on food for kangaroos and wallabies in the coming months," Mr Suridge added.

Some possums had been killed on roads trying to escape the flames, while a range of snakes including pythons and death adders had also sought refuge on roads and fire trails and the height of the blaze.

Of concern is that the fire destroyed a large area of habitat for the endangered Eastern Bristlebird, which Mr Suridge said would expose the birds to more predators.

He said the birds' nesting season had ended, which would help reduce the number killed in the fire, however Eastern Bristlebirds are renowned as not being strong fliers, and so bush fire presented a major hazard for the species.
