Inside the Zoo: Down Under

The zookeepers must anesthetise a sick silverback and transport him to the wildlife hospital. The vets help an injured albatross. And an overprotective rhino won't let anyone near her new-born calf.

Keepers try to cool the elephants down in a record-breaking heatwave. Two platypuses are heading to America. Staff treat a sick funnel-web spider. And it's breeding season for the little penguins.

The largest bushfires on record cause devastation so the vets take the battle to save Australia's wildlife to the frontline. And solving the mystery of an injured Californian sea lion is problematic.

Taronga's vets have grave concerns for a badly-injured, pregnant ringtail lemur and her unborn baby. And staff fight to save an entire species from extinction.

Taronga's keepers get up close to their elephants at bath time, and anxious zoo staff wait patiently for the long overdue birth of a rare baby bongo

Taronga's vets treat a python with chronic back pain, and staff throw a party for the zoo's oldest resident, Esmerelda, the 103-year-old giant Aldabra tortoise
