Vehicle registration plates of Australia

Australian vehicle registration plates or number plates are issued by state, territory, and Commonwealth governments, and the armed forces of Australia. The plates are associated with a vehicle and are generally intended to last for the time the vehicle remains registered in the state, though as they become unreadable (or for other reasons) they may be recalled or replaced with newer ones. Motor vehicle registration in Australia requires annual renewal together with payment of the registration fee
Current standard issue plates.
Motorcycles.
On all motorcycle plates, the legend is embossed at the top and state/territory.
History and Federal numbering scheme.
Standards and federal allocations for all vehicles.
From 1910 onwards all Australian plates started at number 1 and were manufactured in enamel.
Since 1936, Australian plates were to be uniform in size and use embossing in standard Australian dyes, beginning with New South Wales, FCT (now ACT) and Victoria. By 1956 the remaining states and territories moved into standard Australian embossing from either stamped or enamel, standardising in dimensions of × .
From 1951–52, Australian automobiles were to adopt a broad scheme across all states and territories for vehicle number plates. Both New South Wales and Victoria had previously issued plates with 2-letters, 3-digits, white on a black background. However, while implemented, this was not entirely popular as some states and territories preferred their own identity reflected on their vehicles instead. They were meant to use the following proposed scheme:
General Notes: Western Australia deemed itself too large to fit into the proposed scheme and adhered to one of its own devising; plates in the Iaa-nnn series were to be skipped (as a capital I was believed to be easily mistaken for a number 1). This allowed the two populous states with greater registrations of vehicles 6 letter-series each (New South Wales had A to F, Victoria had G to H, and J to M), and others with 3 letter-series (Queensland N, and P to Q, South Australia R to T, Western Australia was allocated U to V). Tasmania was only given one, W, due to its size, and the Australian Capital Territory Y. Z was for federal government department use Australia-wide, the 2nd letter reflecting the commonwealth department, Northern Territory had all numeric supposed to be X, . Letters I and O were deemed to be too similar to 1 and 0 and weren't part of the scheme.
However, the system to be introduced in 1951/52 was not as popular as expected: the Northern Territory refused and continued its previous all-number system. Western Australia soon adopted the scheme, taking charge of the previously NT allocated XAA-000 to XZZ-999 (WAG-000 to WAG-999 they reserved for WA Government vehicles, then extending to XZZ-999). However many WA rural shires chose to issue their own series plates, with initial letters being Shire abbreviations followed by digits, in the WA colour scheme.
All the remaining states and territories stuck to their initial allocations, until the number of registrations became too large for each state and "overflowed" into series otherwise allocated to another state. NSW overflowed from FZZ-999 to GAA-000 (otherwise issued to Victoria) in 1972, Victoria (having reserved the Maa-nnn series for state government registrations) overflowed from LZZ-999 to IAA-000 (previously skipped) in 1974, and then from IZZ-999 to AAA-000 (otherwise issued to NSW) in 1977. South Australia did similar, overflowing from SZZ-999 to UAA-000 etc. (having reserved the Taa-nnn series for trailer registrations).
All states and territories now have adopted their own new series replacing the ABC-123 series and no longer follow grouped allocations as in the 1950s, Instead, alpha/numerics can be in the beginning to the end of the series (except Northern Territory).
Federal Interstate Registration Scheme.
Run years: 1 January 1987 to 1 July 2018.
Heavy vehicles (over 4.5 tonnes GVM) can choose to participate in FIRS scheme.
FIRS plates are WX·00AA, and are green on a reflective yellow background.
FIRS plates are issued by state authorities on behalf of the Commonwealth, and carry the format as specified by the "Interstate Road Transport Regulations 1986 – Reg 21". Federal Interstate-registered vehicles are prohibited from undertaking intrastate journeys and can only be used for cross-border work.
The first character represents the state of issue:
The second character represents the type of vehicle being registered:
The remaining characters are allocated by the issuing authorities. As most interstate transport companies are based on the East Coast, the majority of FIRS plates are registered in NSW and VIC. Some issues originate in QLD or SA, with the remaining states appearing relatively rarely.
A typical plate which might be found on a semi-trailer, registered to a company in QLD would be QT·88MW.
 ALL FIRS scheme plates ceased accepting renewals on 1 July 2018 and FIRS closed on 1 July 2019, after all FIRS registration expired and plates exchanged to the new National Heavy Vehicle scheme/state based registration plates.

National Heavy Vehicle Registration Scheme.
Starting 1 July 2018, a new system was implemented in New South Wales, Queensland, South Australia, Australian Capital Territory and Tasmania. Victoria joined the scheme on 1 October 2018.
Northern Territory has just started using National Heavy Vehicle Plates and abolished the rego stickers effective 1 August 2019 
Western Australia is not participating, hence WA Heavy Vehicles are on state based plates.
The format now in use are:
FB-12AA in Black on white reflection base, and blue band legend with the words NATIONAL HEAVY VEHICLE imprinted on it.
XQ-12AA is for Trucks while YQ-12AA is for Trailers. In this example the prefix denotes X for Trucks and Y for Trailers and the last prefix letter is for home states/territory:
It replaced the state based general series, however not mandatory and owners can request state based personalised plates if they wish to have them. It applies to new heavy vehicles or heavy vehicle requiring replacement of state based general series plates. 4.5 GVM minimum must qualify for the new plates.
Common features.
Plates tend to bear the State or Territory name and perhaps a state motto or slogan at the top and/or bottom of the plate. Recent issues of plates (since the 1980s) also often use the state's colours and may include some imagery related to the state (such as the state's logo as the sequence separator).
Alternative fuel vehicle identification.
Under Part 10 of the Australian Light Vehicle Standards Rules 2015, vehicles powered by fuels other than petrol or diesel (collectively alternative fuel systems) must always display a specific plate that is affixed to both the front and rear license plates. These labels exist to assist emergency services personnel in responding to potential hazards involving such vehicles. Generally, such labels are applied permanently to the registration plate by way of pop rivets or other mechantical fixtures.
The standards were updated in March 2019, to add standards for Hydrogen and electric powered vehicles.
Note: LPG, LNG or CNG vehicles with more than one tank of that type are required to have one additional diamond attached to the front and back license plates.
Labeling for pre 1 January 2019 Hydrogen or Electric vehicles.
Hydrogen or electric powered vehicles built or converted before 1 January 2019 are still subject to relevant state-based standards for their labeling. For example, in Victoria since 2009, such hybrid electric vehicles must display a green diamond sticker with the word "Hybrid" written in white letters.
Commonwealth and military.
Military plates were nnn-nnn with the first digit corresponding to the military district number:
However, new plates issued to the Army are now in this format: nn-nnnn, where the first two digits represent the year the vehicle was registered, e.g. 05-1832.
Current Australian Army registration plate format is A"nn"nnn with this newer format beginning in 2003. The A represents "Army" with the next two digits representing the year the vehicle was first registered. For instance, a 2008 model Toyota Coaster used to transport army cadets might have the plate A08227. This format has also been adopted by the Defence Force, Navy, and Air Force with combinations D"nn"nnn, N"nn"nnn and R"nn"nnn respectively.
The official car of Chief of the Defence Force carries plates ADF1 and official cars for the three service chiefs carry plates ARMY1, NAVY1 or RAAF1.
The Commonwealth Government of Australia used the Z prefix for its government owned vehicles up until 2000 when the Commonwealth Vehicle Registry was closed.
These plates were on a black on white background, usually marked with "C of A" at the top of the plate – an abbreviation of Commonwealth of Australia and the leading Z being red to further distinguish it from other state plates.
Issuance of Z prefixed plates used for same purposes was passed onto the states after 2000. Australian Capital Territory plates started at ZYA-000, Victoria plates started at ZED-000, Queensland plates started at ZQ-0000, New South Wales plates started at ZZZ-000, South Australia plates started at ZSA-000, Western Australia plates started at ZAA-00F and Tasmania plates started at ZTA-000. Only New South Wales and Victoria chose to use their state base colours rather than the standard black on reflective white, with the use of red embossed Z prefix.
Each of the states display their state initials as seen above the numbers instead of the old "C of A" legend.
The Northern Territory still uses the older format and same "C of A" legend at top of the plate.
The registration plate of the Prime Ministerial Limousine was C*1 (i.e. Commonwealth No. 1) with a seven-pointed Commonwealth Star. This has been updated in November 2015 showing C (Australian Government crest image) 1. Other Commonwealth fleet cars for official transport carry "C of A" plates in the form C-nnn.
The Governor-General's official cars do not carry registration plates, but simply depict a representation of the St Edward's Crown. They tend to also have a flag mounted on the official car. Similar plates are used for vehicles carrying Queen Elizabeth II when visiting Australia.
Cars owned by the government have special numberplates, some also have a crown and symbols.
For official visits to Australia, special plates are often put over the top of normal 'Z' plates, depicting the Australian Coat of Arms and, in red 'Visit to Australia' with a numeral. These are not strictly registration plates, but are useful for police and other officials to identify cars in official motorcades.
Diplomatic.
Diplomatic plates are issued to foreign diplomats by the Government of the Australian Capital Territory. They would formerly grant diplomatic immunity to the vehicle and driver from all traffic laws, speed limits, parking infringements and tolls in all reasonable course of duty by a diplomatic officer, in compliance with international treaty, but this is no longer the case. They follow the format of 'DC nnnn', 'DCnnnnn', 'DX nnnn' or 'DXnnnnn', where the first two or three numbers are the code for the home country of the diplomat, and have black text on a powder blue background. DC plates are issued to members of the diplomatic corps, whereas DX plates are issued to persons who are attached to diplomatic missions but are not themselves diplomats, e.g. household staff.
Older issues have no territory identifier, however newer plates have 'ACT' embossed at the top centre of the plate. Newer plates are also written as 'DC' and 'DX', rather than 'D.C.' and 'D.X.' to allow for the inclusion of a greater number of characters in the sequence. A substantial number of older-style plates are still in use, however.
The first two or three numbers appearing in the plate correspond to a specific country, for example 69 is issued to the United Kingdom. The following two digits are typically issued with lower numbers to higher-ranking officials, usually 01 being issued to the ambassador from that country. So DC 6901 would be found on the vehicle of the British High Commissioner to Australia.
The number issued to each country has no particular relevance, and was allocated by ballot. Countries with many vehicles (such as the USA) are allocated two numbers. Before the blue D.C. plates were introduced, diplomatic cars in Canberra carried plates which had white letters on red.
The numbers then correlated to the length of time the particular diplomatic mission had been in Canberra and the British High Commissioner's car proudly carried the plate D.C.1 The replacement arrangement is more egalitarian.
State registration authorities issue CC plates to consular representatives in their relevant state capital.
The ACT Government issues similar plates to representatives of international organisations in the Territory. These plates are also coloured black on powder blue, and follow a format of IO nnnn.
Registration labels abolition.
All states have abolished registration labels for light and heavy vehicles:
