HALLS Gap Zoo will host a family open day on Sunday with all proceeds going to the Country Fire Authority and the State Emergency Service.
Owner Greg Cullel said he and his wife Yvonne appreciated the contributions that both volunteer services
"I think in this world that we've forgotten about volunteering," he said.
"The CFA and SES wouldn't operate without volunteers so why not support something where these guys put in a lot of spare free hours?"
"There wasn't any great light-bulb moment, Yvonne and I strongly believe in supporting community."
He said he hoped people would embrace the spirit of community on the day.
"We hope that people will come with the attitude that this is a great opportunity to give generously towards the CFA and the SES because you're getting an opportunity to come to a zoo for next to nothing," Mr Cullel said.
Member for Lowan Hugh Delahunty will officially launch the new giraffe enclosure and biosecurity fence.
Mr Cullel said the fence has helped prevent unwanted animals, such as foxes and cats, from entering the zoo.
Also at the open day will be a sausage sizzle, jumping castle and face painting.
The zoo will be open to the public from 10am.
Admission is by gold coin donation.
