Why koalas thrive on KI
Koalas were introduced to Kangaroo Island in 1923, brought across from the mainland to safeguard the species when their numbers were collapsing on the southern coast. The island had the right gum trees, the right climate and no natural predators. The population grew faster than anyone expected. Today koalas are widespread across the island, with the densest pockets along river systems on the south side.
The 2020 bushfires affected the koala population in the west, but the recovery has been steady. The east and centre of the island, including the Eleanor River corridor on the south coast, were not burnt and remained healthy refuges. Walking these unburnt corridors is still the best chance most visitors will ever get to see a koala in the wild rather than in a sanctuary.
The two best places to do a koala walk
Two locations are worth your time if you want to actually see koalas in the wild on Kangaroo Island.
1. Little Sahara Adventure Centre's Guided Koala Walking Tour
Little Sahara Adventure Centre runs a 110-minute Guided Koala Walking Tour along the Eleanor River, through a corridor of 500-year-old gum trees. Trained guides walk the same trail every day and know which trees are currently in use, which is why koala sightings are guaranteed on the guided walk. The walk is unhurried, with informative stops along the way and time to actually look up rather than just push through.
The standard Guided Koala Walking Tour is $77 per person with a minimum of 2 participants for the tour to run. Children 0 to 5 are free. There is also a Little Koala Walking Tour, which is a 50-minute walk inside the same 110-minute slot, at $47 per person. Both run at 9am, 10am, 11am, 1:30pm and 2:30pm.
For guests who want to see koalas at their most active, the After Hours Koala Walking Tour runs into dusk at $97 per person. Koalas move between trees to feed around dawn and dusk, so the late tour is the one for serious wildlife watchers. All three tours leave from the on-site centre at 3733 South Coast Road, Vivonne Bay, with covered shoes required. No prams on the bush trail.
2. Hanson Bay Wildlife Sanctuary
Hanson Bay sits between Vivonne Bay and Flinders Chase on the south coast. The sanctuary runs a self-guided koala walk along a creek line lined with manna gums. Daily numbers are limited, which keeps the experience quiet and the impact on the koalas low. Sightings are very likely on most walks, though there is no guarantee because it is self-guided and the koalas move around.
The Hanson Bay walk is a good option for guests who want to set their own pace, take photos at their own speed, and avoid a guided format. For first-time visitors or anyone who wants to know what they are looking at and where, the Little Sahara guided walk is the easier introduction.
What to wear and bring
Covered shoes are required for both walks. The trail is a bush corridor with leaf litter, fallen branches and uneven ground. Activewear, a hat and sunscreen all earn their place. A bottle of water per person is sensible, especially in summer. Binoculars are useful for spotting koalas in the higher branches. The compulsory risk waiver for the Little Sahara guided walk is signed once via SmartWaiver and covers everyone in your group.
When to go
Koalas are mostly active around dawn and dusk, when they move between trees to feed. During the middle of the day they sleep, sometimes deeply, and you will see them but they will not be doing much. If you want to see koalas moving, the After Hours Koala Walking Tour is the option.
Across the year, autumn and spring are the most comfortable. The walks run year-round and the koalas are present year-round. Winter is quieter and the eucalypt foliage is denser, which can make spotting a little harder but the experience more atmospheric.
What's nearby
The koala walk pairs naturally with the rest of the south coast. Little Sahara sits at the same on-site centre, so a morning koala walk and an afternoon on the dunes is a classic pairing. Seal Bay is 30 minutes east. Vivonne Bay is 12 minutes away for a swim or a feed at the general store. Most three-day itineraries thread the koala walk into the same day as Seal Bay and the dunes.
