There are many forms of transport in Australia. Australia is highly dependent on road transport due to its large size. There are more than 300 airports with paved runways. Passenger rail transport includes widespread commuter networks in the major capital cities with more limited intercity and interstate networks. The Australian mining sector is reliant upon rail to transport its product to Australia's ports for export.
Road transport
Road transport is an essential element of the Australian transport network, and an enabler of the Australian economy. There is a heavy reliance on road transport due to Australia's large area and low population density in considerable parts of the country. This is similar to the US. Australia's road network experiences excessive demand during peak periods and very weak demand overnight.
Another reason for the reliance upon roads is that the Australian rail network has not been sufficiently developed for a lot of the freight and passenger requirements in most areas of Australia. This has meant that goods that would otherwise be transported by rail are moved across Australia via road trains. Almost every household owns at least one car, and uses it most days.
There are three different categories of Australian roads. They are federal highways, state highways and local roads. In 2024, Australia had an estimated 476,000 km of paved roads.
Victoria has the largest network, with thousands of arterial (major, primary and secondary) roads to add.
The majority of road tunnels in Australia have been constructed since the 1990s to relieve traffic congestion in metropolitan areas, or to cross significant watercourses.
Cars Australia has the thirteenth-highest level of car ownership in the world. It has three to four times more road per capita than Europe and seven to nine times more than Asia. Australia also has the third-highest per capita rate of fuel consumption in the world. Melbourne is the most car-dependent city in Australia, according to a data survey in the 2010s, having over 110,000 more cars driving to and from the city each day than Sydney. Perth, Adelaide and Brisbane are rated as being close behind. All these capital cities are rated among the highest in this category in the world (car dependency).Urban Australia: Where most of us live. CSIRO. Retrieved 15 July 2012. The distance travelled by car (or similar vehicle) in Australia is among the highest in the world.
Electric vehicles
The adoption of plug-in electric vehicles in Australia is driven mostly by state-based electric vehicle targets and monetary incentives to support the adoption and deployment of low- or zero-emission vehicles. The monetary incentives include electric vehicle subsidies, interest-free loans, registration exemptions, stamp duty exemptions, the luxury car tax exemption and discounted parking for both private and commercial purchases. The Victorian and New South Wales governments target between 50% and 53% of new car sales to be electric vehicles by 2030.
Public transport in Australia
Suburban rail Sydney, Melbourne, Brisbane, Perth and Adelaide have extensive suburban rail networks which have grown and expanded over time. Australian suburban rail typically operates with bidirectional all-day services with Sydney, Melbourne, and to a lesser extent Perth and Brisbane's systems operating with much higher frequencies, particularly in their underground cores. Sydney Trains operates the busiest system in the country with approximately 1 million trips per day. Metro Trains Melbourne operates a larger system albeit with a lower number of trips.
Trams and light rail
Trams have historically operated in many Australian towns and cities, with the majority of these being shut down before the 1970s in the belief that more widespread car ownership would render them unnecessary. Melbourne is a major exception and today has the largest tram network of any city in the world. Adelaide retained one tram service — the Glenelg tram line, since 2008 extended to Hindmarsh and the East End. Trams once operated in Sydney, Brisbane, Perth, and Hobart, and a number of major regional cities including Ballarat, Bendigo, Broken Hill, Fremantle, Geelong, Kalgoorlie, Launceston, Maitland, Newcastle, Rockhampton, and Sorrento.
The Inner West Light Rail opened in Sydney in 1997 with the conversion of a disused section of the Metropolitan Goods line. The CBD and South East Light Rail opened to Randwick in December 2019 and Kingsford in April 2020. A light rail system opened on the Gold Coast in 2014. A line opened in Newcastle in February 2019 and one in Canberra opened in April 2019.Light rail in Newcastle opening from Monday 18 February Transport for NSW 3 February 2019Start date revealed for Canberra’s light rail system Canberra Times 19 March 2019
Rapid transit Sydney is the only city in Australia with a rapid transit system. The Sydney Metro currently consists of one 52 km driverless line, connecting Tallawong and Sydenham, and is scheduled to be extended to Bankstown in 2025 under the Metro North West & Bankstown Line. Upon completion, it will complete the Sydney Metro City & Southwest project to form a 66 km network with 31 metro stations.
The Sydney Metro West and Sydney Metro Western Sydney Airport are currently under construction. The former aims to connect Westmead to the Sydney CBD, via stations including Parramatta, Sydney Olympic Park, Five Dock, and the Bays Precinct, and is scheduled to be completed by 2032. The latter aims to connect St Marys and Badgerys Creek Aerotropolis via Western Sydney Airport, scheduled to be completed in 2026, aligning with the opening of the airport.
Adelaide, Brisbane, Melbourne, Perth, and Sydney's commuter systems are all partially underground and reflect some aspects of typical rapid transit systems, particularly in the city centres.
Intra-city public transport networks The following table presents an overview of multi-modal intra-city public transport networks in Australia's larger cities. The only Australian capital cities without multi-modal networks are Darwin and Hobart. The table does not include tourist or heritage transport modes (such as the private monorail at Sea World or the tourist Victor Harbor Horse Drawn Tram).

Intercity rail transport
The railway network is large, comprising a total of 33,819 km (2,540 km electrified) of track: 3,719 km broad gauge, 15,422 km standard gauge, 14,506 km narrow gauge and 172 km dual gauge. Rail transport started in the various colonies on different dates. Privately owned railways started the first lines, and struggled to succeed on a remote, huge, and sparsely populated continent, and government railways dominated. Although the various colonies had been advised by London to choose a common gauge, the colonies ended up with different gauges.
Inter-state rail services Journey Beyond operates four trains: the Indian Pacific (Sydney-Adelaide-Perth), The Ghan (Adelaide-Alice Springs-Darwin), The Overland (Melbourne-Adelaide), and the Great Southern (Brisbane-Melbourne-Adelaide). NSW Government owned NSW TrainLink services link Brisbane, Canberra, Melbourne, Dubbo, Broken Hill, Armidale, Moree and Griffith to Sydney. Since the extension of the Ghan from Alice Springs to Darwin was completed in 2004, all mainland Australian capital cities are linked by standard gauge rail, for the first time.
Intra-state and city rail services There are various state and city rail services operated by a combination of government and private entities, the most prominent of these include V/Line (regional trains and coaches in Victoria); Metro Trains Melbourne (suburban services in Melbourne); NSW TrainLink (regional trains and coaches in New South Wales); Sydney Trains (suburban services in Sydney); Queensland Rail (QR) operating long-distance Traveltrain services and the City network in South-East Queensland, and Transwa operating train and bus services in Western Australia.
In Tasmania, TasRail operates a short-haul narrow gauge freight system, that carries inter-modal and bulk mining goods. TasRail is owned by the Government of Tasmania and is going through significant below and above rail upgrades with new locomotives and wagons entering service. Significant bridge and sleeper renewal have also occurred. The Tasmanian Government also operates the West Coast Wilderness Railway as a tourist venture over an isolated length of track on Tasmania's West Coast.
Mining railways Six heavy-duty mining railways carry iron ore to ports in the northwest of Western Australia. These railways carry no other traffic and are isolated by deserts from all other railways. The lines are standard gauge and are built to the heaviest US standards. Each line is operated by one of either BHP, Rio Tinto, Fortescue and Hancock Prospecting.
A common carrier railway was proposed to serve the port of Oakajee Port just north of Geraldton, but this was later cancelled after a collapse in the iron ore price.Mixed fortunes for Western Australian rail projects International Railway Journal January 2013 page 8
Cane railways In Queensland, 19 sugar mills are serviced by ~3,000 km of narrow gauge ( gauge) cane tramways that deliver sugar cane to the mills.
