Urban rail transport forms a vital part of transportation in major Australian cities.

The Commonwealth governmentBureau of Infrastructure, Transport and Regional Economics and industry peak body Australasian Railway Association, who jointly publish theTrainline statistical report categorise Australian passenger systems as "urban" or "non-urban".^[1]

Urban networks are further classified as "light rail" or "heavy rail".^[1]Light rail in Australia includes established tram networks in Melbourne and Adelaide continuously operating in various forms since the 19th century, as well as networks in other cities newly constructed after the cessation of tram operation. Heavy rail networks primarily describe passenger operations over parts of mixed-traffic rail systems centred on capital cities and also includes theSydney Metro system, which operates on its own dedicated corridor.

Non-urban passenger networks are classified according to their passenger task. "Inter-city" or "regional" networks are defined to be those whose primary market "...include[s] daily commuting or day return business or leisure travel" to major cities and are therefore included in this article. Other markets, such as long-distance operations between cities and regional centres, tourist-focused and heritage services, are excluded from this list.^[1]

Average daily patronage, where possible, is taken from the last calendar or financial year. System lengths are given in route kilometres. The largest, most extensive urban (as distinct from interurban) system is found inMelbourne, while the system with the highest patronage is found inSydney. Patronage figures are for 2018–19 unless otherwise stated.
