There are two practical ways to reach Kangaroo Island from Adelaide: drive south to Cape Jervis and take the SeaLink vehicle ferry across to Penneshaw, or fly REX from Adelaide Airport into Kingscote and pick up a hire car on arrival. This calculator turns your party size, whether you're bringing a car, and your trip length into an indicative cost and door-to-door time comparison so you can pick the right option.
The ferry route involves roughly 1.5–2 hours of driving from central Adelaide down the Fleurieu Peninsula to Cape Jervis, then about a 45-minute crossing on the SeaLink ferry. It's the cheaper option for most groups, the only sensible choice if you want to bring your own vehicle, and it gives you complete flexibility once you're on the island. Trade-off: it eats most of a day at each end of the trip.
Flying with REX from Adelaide Airport to Kingscote takes around 30 minutes in the air, with a total door-to-door time closer to 2.5–3 hours once you include check-in, security and collecting a hire car. It wins clearly on time for solo travellers, couples on short trips and anyone trying to make a one-day visit work — but you'll always need to factor in hire-car costs, and flight schedules are limited compared with ferry sailings.

Our recommendation
Take the ferry
Bringing your own car means the ferry is almost always the right call — you skip daily hire costs and have full flexibility on the island.
Estimates only. These are indicative ranges, not quotes. Confirm current fares with SeaLink and your airline (REX) before booking. Fares vary by season, day of week and lead time.
How we built these ranges
Ferry costs combine SeaLink's published return passenger and standard vehicle fares with typical drive time from Adelaide to Cape Jervis and the crossing itself. Flying costs use indicative 2026 REX return airfares between Adelaide and Kingscote plus a hire-car allowance scaled to your trip length. Door-to-door time includes drive-to-departure time and realistic check-in or vehicle-load buffers, not just the headline crossing or flight figure. None of this is a quote.
