Australia and New Zealand are countries defined by water — a continent girt by sea and two main islands separated by one of the world's more dramatic straits. Both countries have ferry services that matter in practical travel terms, from the scenic Cook Strait crossing that every South Island visitor should consider, to the Bass Strait overnight to Tasmania, the harbour ferries that define daily life in Sydney and Auckland, and the passenger ferry to Kangaroo Island. Here is how they all fit together.
Cook Strait: connecting New Zealand's two islands
The Cook Strait between Wellington (North Island) and Picton (South Island) is the key ferry crossing in New Zealand — around 92 km of sometimes-turbulent water that separates the two halves of the country. Two operators share the route:
Interislander
Interislander, operated by KiwiRail, is the longer-established service. Crossings depart from Wellington's central ferry terminal (within walking distance of the railway station) and arrive at Picton in the Marlborough Sounds, taking approximately 3 hours 15 minutes to 3 hours 30 minutes. Multiple sailings a day run in both directions. Interislander carries vehicles as well as foot passengers, and the vessel passes through the Marlborough Sounds on approach to Picton — a genuinely scenic finale to the crossing.
New ships are being introduced — the current programme involves modern hybrid ferries replacing the older fleet, which may affect schedules and vessel types; check the current situation when booking.
Bluebridge
Bluebridge Cook Strait Ferry offers the same Cook Strait crossing and is often slightly cheaper than Interislander, making it the preferred choice for budget-conscious travellers. Crossings take around 3 hours 30 minutes to 4 hours, and both foot passengers and vehicles are carried. Bluebridge's Wellington terminal is close to Interislander's. The service runs multiple times daily on most days, with reduced frequency in shoulder season.
For either operator, book ahead if you are taking a vehicle — vehicle space is limited and fills at peak times (school holidays, summer). Foot passengers have more flexibility but should still book at busy periods. Both operators run to and from the same Picton town terminal, from which rail connections (Coastal Pacific to Christchurch) and onward buses are available.

Bass Strait: the Spirit of Tasmania
The Spirit of Tasmania ferries connect Melbourne (Geelong) with Devonport, Tasmania, crossing the notoriously rough Bass Strait in about 9–11 hours. Services typically depart in the evening and arrive the following morning — making the overnight crossing a practical way to transport a car to Tasmania while sleeping at sea. Daytime crossings also operate at certain times of year.
TT-Line operates the Spirit of Tasmania vessels. Accommodation ranges from reclining seat to cabin options (inside four-berth, and inside/outside two-berth cabins), and higher-grade cabins are notably more comfortable than the seats for the overnight crossing in Bass Strait conditions. A car and driver typically requires an advance booking; foot passengers have more last-minute flexibility, though peak summer sailings sell out.
Note: as of 2024, the main terminal in Melbourne was transitioning toward Geelong — check the current departure point when booking, as it has changed in recent years and may change again.
Bass Strait is often rough. If you are prone to seasickness, take precautions seriously — the swells between Victoria and Tasmania can be significant, particularly in winter and spring.
Sydney Harbour ferries
Sydney Ferries (operated under the Transport for NSW network) is one of the world's most scenic urban ferry systems. Ferries serve the harbour and its many inlets from Circular Quay, connecting suburbs like Manly, Mosman, Balmain, Parramatta and more. For visitors, the ferry to Manly is particularly popular — it crosses the harbour mouth and takes about 30 minutes, offering views of the Sydney Opera House and Harbour Bridge that no bus route can match. The Manly ferry is covered by an Opal card (the Sydney transport card), making it straightforwardly priced alongside other public transport.
Ferries also serve Cockatoo Island (a historic former prison and shipyard now open as a camping and heritage site) and are a practical way to reach several waterfront neighbourhoods that are awkward by bus or train.
Auckland harbour ferries
In Auckland, Fullers360 operates the main passenger ferry network from the downtown Ferry Building at Quay Street. The most popular route connects Auckland city with Devonport on the North Shore (about 12 minutes) — a popular tourist excursion and a practical commuter route. Ferries also serve Waiheke Island (about 35 minutes), which has its own wine country and beaches and is Auckland's most popular day trip. Great Barrier Island can also be reached by ferry, though the crossing takes around 4 hours and serves more as a passenger supply route than a tourist day trip.
Waiheke Island ferries are worth booking ahead in summer (December to February) as they are popular and the faster services fill. A ferry-and-wine-experience package is widely offered by Fullers360 if you want a bundled day-trip option.
SeaLink: Kangaroo Island from South Australia
SeaLink operates the passenger and vehicle ferry between Cape Jervis (about 100 km south of Adelaide) and Penneshaw, Kangaroo Island. The crossing is short — about 45 minutes — but the ferry is the only surface connection to Kangaroo Island, making it essential for any visitor who wants to bring a vehicle. SeaLink also operates connecting coach transfers between Adelaide and Cape Jervis, making a car-free visit to Kangaroo Island achievable (though the island itself is large and somewhat awkward without a vehicle).
Vehicles should be booked ahead, particularly in peak season and around South Australian school holidays. The crossing itself is calm on most days, sheltered by Gulf St Vincent waters.
Other Australian coastal and river ferries
Several other ferry services are worth knowing about for specific itineraries:
- Fraser Island (K'gari), Queensland: Passenger and vehicle ferries from River Heads (near Hervey Bay) and from Inskip Point (Rainbow Beach) serve the world's largest sand island — now officially called K'gari. Ferries run frequently and the crossing is very short.
- North Stradbroke Island, Queensland: Stradbroke Ferries connects Cleveland (east of Brisbane) to Dunwich on the island. A popular weekend escape from Brisbane.
- Magnetic Island, Queensland: Fantasea Cruises connects Townsville to Magnetic Island in about 20 minutes. A pleasant day trip or base for the Great Barrier Reef region.
Booking tips
For Cook Strait crossings, book directly with Interislander (greatjourneysofnz.co.nz) or Bluebridge (bluebridge.co.nz). For the Spirit of Tasmania, book through TT-Line (spiritoftasmania.com.au). SeaLink bookings are at sealinktravel.com.au. All of these accept online bookings well in advance — and for vehicle travel, early booking is strongly recommended in peak season.

Frequently asked questions
How long is the Cook Strait ferry crossing?
Around 3 hours 15 minutes on Interislander and 3.5–4 hours on Bluebridge, depending on the service. Both run from Wellington to Picton (and the reverse) multiple times a day.
How rough is the Bass Strait crossing on the Spirit of Tasmania?
Bass Strait has a reputation for rough seas, particularly in winter and spring. The overnight crossing can be uncomfortable in heavy swells. Cabin accommodation and seasickness medication are both worth considering if you are sensitive to motion.
Do I need to book the Cook Strait ferry in advance?
For foot passengers, some flexibility is possible outside peak times. For vehicles, booking ahead is essential — vehicle space is limited and fills during New Zealand school holidays, summer, and the Easter period.
How do I get to Kangaroo Island by ferry?
Take SeaLink from Cape Jervis, about 100 km south of Adelaide. The crossing to Penneshaw takes around 45 minutes. SeaLink also runs connecting coaches from Adelaide to Cape Jervis if you are travelling without a car.
