A Christmas in July dinner will be held at the restaurant on Bentinck Street, with proceeds from the night to go towards supporting Miss Traill's House and Garden.

Susan Morris, of Miss Traill's House and Garden, said anyone is welcomed on the night.

"This is an event that is held annually and it's a really great celebration of the house and garden," she said.

"Some people think it's only for National Trust members, but everyone is welcome.

"Miss Traill's House and Garden is the only National Trust place in Bathurst, so this dinner is a great way to support it."
