This sweet moment was captured on camera by the wildlife carers at Port Stephens Koalas.

Tiny Morton, weighing just 810 grams, came into the care of the sanctuary in June after his mother was hit by a car.

Morton has gone from strength to strength at Port Stephens Koalas, eating up gumleaves and formula to gain a healthy weight.
