The Rex route
Rex runs the Adelaide to Kingscote (KGC) route, multiple times most days. The aircraft is a Saab 340 turboprop, 34 seats, no business class, no in-flight service beyond a bottle of water. The flight itself is around 40 minutes, low enough that you get a proper view of the Fleurieu Peninsula on the way out and the north coast of KI on approach.
Departures from Adelaide use the regional terminal, not the main domestic terminal. Allow extra time if you are connecting from a Jetstar, Virgin or Qantas flight; the regional terminal is a short walk or shuttle from the main one. Kingscote airport is small enough to clear in 10 to 15 minutes, including bag collection and a car-hire desk visit.
What it costs
The base Rex Adelaide to Kingscote fare is around $169 one-way. Sale fares dip to $129 when they appear (usually a few weeks out, mid-week dates). A return lands between $260 and $340 depending on how far ahead you book. There is one fare class for most travellers, no separate economy and economy-plus shenanigans.
Compare that to the ferry: a solo adult foot passenger return is around $108. So the ferry beats the flight on raw fare if you are travelling alone and counting only the crossing. But Rex saves you 90 minutes each way on the Cape Jervis drive and another 45 minutes on each ferry leg, which is most of a half-day round trip. If your time is worth $20 an hour, the flight pays for itself.
When flying beats the ferry
- You are travelling solo or as a couple without a car. The fare gap shrinks once you are not paying for vehicle freight.
- You are connecting from interstate. You are already at Adelaide Airport, so jumping onto a 40-minute Rex hop beats taxiing 90 minutes to Cape Jervis.
- You only have a weekend. Saving 3 to 4 hours in transit each way is the difference between a usable Saturday and a wasted one.
- You are sensitive to swell. Backstairs Passage can roll. The Saab does not.
When the ferry still wins
- You want your own car on the island. There is no other way to get it across.
- You are a family of four or more. Vehicle freight aside, the per-passenger ferry fare wins once you stack three or more.
- You are staying five days or more. The flight saving on a single trip matters less when amortised over a longer stay, and your own car gives you more flexibility.
- You are on a hard budget. The ferry foot-passenger fare of $108 return is the cheapest non-tour entry to the island.
Connecting from interstate
If you are flying in from Melbourne, Sydney or Brisbane, Rex sells connecting itineraries through Adelaide. Allow at least 90 minutes between your arriving domestic flight and the Rex departure. The regional terminal is a short walk from the main domestic terminal, but you will need to clear bags and re-check them if you are not on a single ticket.
Last Rex flight of the day out of Adelaide is usually mid-afternoon. If your inbound interstate flight lands after 4 pm, you will need to overnight in Adelaide and fly the next morning. We have written full guides for the two main origin cities: from Melbourne and from Sydney.
Booking tips
A few things that save money or grief.
- Book direct on the Rex site. Third-party aggregators sometimes mark up regional carriers and rarely show the full schedule.
- Mid-week beats weekend on both price and availability. Tuesday and Wednesday flights are the quietest.
- Watch for cancellations. Rex occasionally trims off-peak schedules with little notice. Keep a screenshot of your booking and a Plan B in the back of your head.
- The morning out, afternoon back trick works here too. First flight out of Adelaide gets you to Kingscote in time for a full day. Last flight back gets you a full final day.
So, fly or ferry?
Solo or weekend couple, fly. Family or anyone bringing a car for three nights plus, ferry. If you genuinely cannot decide, look at the total cost (transport plus accommodation plus food) for both options. The transport difference is usually under 10 per cent of the trip total. Pick the one that feels less stressful to plan.
