Two baby giraffes have been born just days apart in what Zookeeper Chad Staples describes as "rare" and "perfect" births.
The female calves were born at Mogo Wildlife Park on December 27 and 31.
Zookeeper Chad said mothers normally showed signs such as swelling, walking differently or waxy teats indicating the birth was imminent.
"These two girls were a bit more secretive," he said.
