I have visited Billabong Zoo Port Macquarie a number of times, and it always delights me to watch the beautiful animals and birds. Billabong Zoo Koala Breeding Program Billabong Zoo, known for its koala breeding program, plays a crucial role in enhancing koala populations across Australia by providing genetically strong bloodlines to zoos and sanctuaries in NSW, Victoria, and Queensland. The zoo houses up to 20 koalas at a time, each cared for meticulously by dedicated staff.
