The best time to book a Kangaroo Island wildlife tour
Sea lions rest at Seal Bay in every month, and koalas sleep in the gums whatever the date. What shifts through the year is the weather, the crowds and a few seasonal extras offshore and in the bush. This guide sets out when we would go and which days we would leave alone.
What stays the same all year
The headline animals of Kangaroo Island do not migrate. Australian sea lions haul out on the sand at Seal Bay in every month, and koalas sit in the manna gums whatever the weather.
Kangaroos and tammar wallabies graze the edges of paddocks around dawn and dusk the whole year round. So there is no closed season for a wildlife tour here, only better and worse days to be outdoors.
Our pick, the Kangaroo Island Trails day tour from ~$287, lists the same core stops whatever the month. Its day always includes the guided beach walk at Seal Bay and the two big sights in Flinders Chase National Park.
What changes is the frame around the animals. Weather decides how pleasant the long walks feel, and school holidays decide how hard it is to get a seat on the ferry or a small tour.
| Stretch of the year | Weather, roughly | Seasonal extras | What we think |
|---|---|---|---|
| September to November | Warming, showers easing | Wildflowers, joeys in pouches | A strong choice |
| December to February | Dry, highs about 24–26 °C (75–79 °F) | Long light evenings | Busy holidays, fire-danger days |
| March to May | Mild and often settled | Animals out before sunset | Our quiet favorite |
| June to August | Wet, highs about 14–16 °C (57–61 °F) | Southern right whales offshore | Rough crossings, few crowds |
Spring, for joeys and wildflowers
From September to November the island warms up and the bush comes into flower. Spring is when many kangaroo and wallaby joeys start poking their heads out of the pouch, though breeding here is spread out and young ones turn up in other months too.
The days are long enough for a full tour without rushing, and the summer crowds have not arrived yet. Wind still blows hard at the west end, so pack a warm layer even on a sunny morning. Our guide to Remarkable Rocks and Admirals Arch covers that exposed corner.
Koala mothers carrying young are often seen from late spring into summer. Once a joey leaves the pouch it rides on its mother's back, so look for a second, smaller shape tucked into the fork of the tree.
Summer heat, holidays and fire days
Summer highs sit roughly at 24–26 °C (75–79 °F), with hotter spells when the wind blows off the mainland. Rain is rare and the evenings stay light until late, which suits a long day outdoors.
Crowds are the downside. School holidays from late December through January fill the ferries and small tours first, and Easter does the same later on. If your dates fall there, book the crossing and the tour together; our ferry or flight guide explains both ways over.
Summer is also bushfire season across South Australia. On days of extreme fire danger, parks may close and tours may change their plans, so check the fire rating and your listing before you go. Nobody can promise that a trip goes ahead.
The hottest midsummer days are the ones we would avoid for long walks. The beach at Seal Bay has no shade, and the granite at Remarkable Rocks throws the heat back at you. Carry water and wear a hat with a brim.
A small group that starts at your door
Kangaroo Island Trails collects you from your accommodation in Kingscote or Penneshaw and keeps the group to 11 guests at most. Seal Bay and Flinders Chase entry are included, the ferry is not, so cross the day before. Viator shows 4.8 from 100+ reviews.
Autumn, the calm middle
March to May is our quiet favorite. The heat eases, the holiday rush has gone apart from Easter, and the sea can be settled enough for the boat trips out of Penneshaw.
Evenings come sooner in autumn, and that suits wildlife watching. Kangaroos and wallabies start feeding before sunset, so you may see them on the drive back from a day tour without staying out late. If you have your own car, drive slowly at dusk.
Winter, whales and rough water
From roughly June to October, southern right whales travel along the South Australian coast, and some pass close to the island. The 75-minute coastal safari from ~$62 lists seasonal whales among the animals it looks for, next to bottlenose dolphins.
Winter highs sit at about 14–16 °C (57–61 °F), with rain and strong winds. Backstairs Passage can be lumpy for the ferry, and very windy days are the ones to skip for an open boat. Our dolphin cruise or swim guide describes the ride.
The upside is space. Fewer visitors means easier bookings and quieter beach walks, and the sea lions do not mind the cold at all. Pack a waterproof jacket and a warm layer for any day out.
Days we would skip
- The hottest midsummer days, if you plan long walks at Seal Bay or the west end
- Extreme fire-danger days, when parks may close (check before you go)
- Very windy winter days, for the open-boat safari out of Penneshaw
- Your last day on the island, for anything that could make you miss the ferry back
None of these rules out a visit. They are the days when a different plan, or a different date, gives you more for the same money.
Fitting the season to your tour
If you are staying on the island, a spring or autumn day with Kangaroo Island Trails is our first choice. It needs a night on the island beforehand, so put the crossing on the previous day. The tour price comparison shows what each option includes.
Short of time? The Hanson Bay koala walk from ~$32 lasts 1.5 hours and has several departure times, so it slots in around rain or wind. Our page on where the koalas are explains why the west end matters.
Whatever the month, the animals you are likely to meet stay much the same. Our list of nine animals to look for says where tours tend to find each one.
