The tiny youngsters came into care weighing 16 grams, with no fur, eyes closed and transparent skin, so tiny that they were nearly impossible to feed.

"In the end I had to feed them using a paediatric catheter tube on the end of a syringe, as their mouths were so small," carer Nicole said.

"Because the babies were so tiny they required feeding six times a day until their weight stabilised.

"This process would take at least 45 minutes each time and still they lost a few grams in the beginning, due to the stress of losing their Mum."

In only a few weeks the babies would open their eyes and begin to see. In a few weeks more, they would begin to lap milk from a dish and a few months after that they would venture outside into an aviary to begin to get a taste of life in the wild.

After a slow and steady start and almost six months care the gliders were prepared for release.

"Finding the perfect location to release these little guys became my mission in life, with help from National Parks and Wildlife Service we managed to find a location close to where they were found, which was perfect," Nicole said.

Supplementary feeding and housing boxes were installed, as well as three infrared cameras on their home tree with pictures sent to ensure they were adjusting to life in the wild.

After feeding and monitoring for three weeks, the cameras were removed and the gliders were on their own.

"It was such an emotional journey with these guys, never knowing if they would make it in the beginning, to removing the cameras and trusting they were doing well in the wild," Nicole said.

Sugar gliders are small, beautifully marked omnivorous and nocturnal marsupials who take up residence in the hollows of trees.

They get their name from the flaps of skin between their front and back legs that they stretch out to glide from branch to branch.

They are not commonly seen and can become prey to cats, barbed wire and habitat loss.
