The late Steve Irwin's family, Terri, Bindi, and Robert, run the Australia Zoo and travel the world to protect and celebrate animals.

Terri sedates Hunter, the blind Sumatran tiger, for his annual eye check. Meanwhile, the zoo keepers prepare Scarlett, a young giraffe, for her journey to South Australia to reunite with her family.

The family prepares Croc One, Steve Irwin's research ship, to release a sea turtle back into the wild. After a marathon road trip, Scarlett the giraffe is reunited with her grandmother. Meanwhile, at the zoo's wildlife hospital, a wild echidna is discharged.

Robert follows in Steve's footsteps wrangling Utah, a highly venomous 12-foot king cobra. Dr. Amber visits Tandora to care for wild koalas. Back at the Zoo, an old injury flares up for Bruce the Brolga, a bird who's been in the Irwins' care for 26 years.

The Australia Zoo's alligator snapping turtles need a health check and it's Robert's job to protect the keepers and vets from their fierce bites. Terri and Bindi welcome seven new lemurs from the U.S. The Zoo's rescue unit is called to save possums caught in a chimney.

Following Steve's dream of global conservation, the Irwins travel to South Africa. Terri helps release a wild leopard, Bindi learns from the all-female anti-poaching squad the Black Mambas and Robert attempts to photograph Africa's "Big Five."

It's all hands on deck in the Australia Zoo's Mammal Department -- Rosie the Giraffe is ready to give birth! Robert has a bloody encounter with a wild python that's entered an enclosure and Terri helps the keepers wrangle Chief the Tasmanian devil.

While Bindi and the keepers ready Sophie the baby giraffe for her first steps into her enclosure, Robert helps to hand-raise another baby: Melman the kangaroo. Terri oversees a health check for one of the zoo's favorite characters, Ravi the red panda.

Terri welcomes Mballa, a new cheetah cub from South Africa, to the Australia Zoo family. Meanwhile, Robert sets out to save a stranded platypus and Bindi prepares to meet Bert the koala joey as he emerges from his mother's pouch for the first time.

Wes and Robert remove eggs from the nest of saltwater crocs Terra and Bosco in a nerve-wracking but necessary venture. Bindi tends to the training of otters Percival and Daisy, and Terri makes a zoo volunteer's dream come true.

Robert travels to Australia's Great Barrier Reef to help conduct research on manta rays. The Zoo's Rescue Unit, Wildlife Hospital and volunteers team up to save a baby wallaby struggling to survive. Bindi gets up close and personal with Archie the dingo.

Terri attends the exam of Charlie the tiger to determine if his tumors were successfully treated. Bindi and the Small Mammal Team help develop a vaccine for Eden the Tasmanian devil. Robert discovers the true genders of the Zoo's shingleback lizards.

Love is in the air at Australia Zoo! Terri helps determine if Caballe the rhino is pregnant, while Robert matchmakes with Coconut and Goliath, the Zoo's Aldabra giant tortoises. Bindi meets some newborn lemur twins, and Cleo the python gets help shedding.

The family makes their annual trip to the Steve Irwin Wildlife Reserve to capture, study and release wild crocodiles. They continue the mission started by Steve and Terri, providing scientific research vital to the protection of Australia's apex predators.
