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 at 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.
NSW owned CountryLink services link Brisbane, Canberra and Melbourne via 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.
Four 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.
In 2006, a fifth iron ore railway is proposed by the Fortescue Metals Group, while a sixth common carrier railway is proposed to serve the port of Oakajee just north of Geraldton.
In Queensland about 15 sugar mills have narrow gauge (gauge) cane tramways that deliver sugar cane to the mills.
The Australian Highway System is broken up into 3 different categories for rural Australia:
The road network is again extensive, comprising a total of 913,000 km broken down into:
The majority of road tunnels in Australia have been constructed since the 1990's to relieve traffic congestion in metropolitan areas, or to cross significant watercourses. See Tunnels in Australia for a listing.
Australia's inland waterways are not a significant means commercial transport. In the 19th century, paddle steamers were used on the Murray-Darling Basin to transport produce such as wool and wheat but the water levels are highly unreliable, making the river impassable for large parts of the year. The steamers proved unable to compete with rail, and later, road transport. Traffic now on inland waterways is therefore largely restricted to private recreational craft.
There are many airports around Australia paved or unpaved. A 2004 estimate put the number of airports at 448. The busiest airports in Australia are:
Total: 305
