Taronga Western Plains Zoo are celebrating their most recent additions, with a pair of Galapagos Tortoise hatchlings born in January doing well.
They will grow to weigh more than 300 kilograms when they reach full size but for now the pair weigh just 110 grams and can fit in the palm of your hand.
It will be approximately 20 to 25 years before they reach adult size.
The duo, who are yet to be named, are currently being kept in an off-display area that is temperature controlled to ensure conditions are just right.
It is just the second time the zoo has successfully bred Galapagos Tortoise. Their first hatchling, NJ, arrived in 2011 and was the first successful breeding of the species in Australasia.
Since then team at the zoo have worked tirelessly to adjust their incubation techniques and tortoise supervisor Jennifer Conaghan believes they are getting it right.
"It took a while for the males to reach sexual maturation but they are getting better," she said.
"We are hopeful we can continue to build on this success again later this year."
The zoo has three full size males, two full size females, three-year-old NJ, who is the size of a dinner plate and weighs 1.1 kilograms, and the two new additions.
