The wildlife park, run by the Radnidge family, recently successfully renewed its accreditation.

In 2007, Symbio Wildlife Park and Adelaide Zoo became the first zoos in the world to receive accreditation through the program, which has enhanced animal welfare standards within the industry internationally.

ZAA president Karen Fifield said the accreditation program had created a new standard for animal welfare and Symbio was at the forefront.

"Being accredited means our members can be proud of providing our animals with the best possible care," she said.

"Rather than simply making sure animals are not experiencing negative welfare states, the program goes a step further to focus on delivering positive welfare outcomes from five domains."

The domains are nutrition, environment, health, behaviour and the mental state of animals in the care of zookeepers.

Ms Fifield said for Symbio to gain the accreditation meant it was ensuring its animals were given the best possible care and were all living in a positive state.

Symbio Wildlife Park managing director John Radnidge said it was a privilege and honour to be acknowledged for the level of care and love the zoo showed its animals.

"They are our family and every one of us put our hearts and souls into Symbio, and you can tell, you can tell by just how happy our animals are, how well they are cared for, and the space they call home," he said.

ZAA is the peak body representing the zoo and aquarium community throughout Australasia. It has 91 member organisations, including 86 zoos.
