General series.

 Motorcycles: S00·ABC
In South Australia, until October 2008, standard registration plates followed the 3-letter, 3-number (aaa-nnn) standard used by New South Wales and Victoria: their series, introduced in 1966 started with RAA-000 and finished at XUN-299.
Since October 2008, South Australian general issue plates follow the format Snnn-aaa, the S signifying South Australia. No slogan is printed on these plates, rather they contain the words 'South Australia'.
Up until 1966 South Australian plates were all numerical, and were subject to re-issue, in either nn-nnn or nnn-nnn format, white on black background. These plates are available for re-issue at a fee.
Post 1966 motorcycles were initially issued with RA-000 to SZ-999 then TAA-000 to TIZ-999. Trailers were issued TJA-000 to TZZ-999. When the Taa-nnn issues were exhausted, motorcycles were issued with high end YYA-000 to YZZ-999,then started at YKA-000 to YKA-799, and trailers issued YAA-000 to YIL-999. Since 2008, newly issued plates are in the form S000-AAA and motorcycles as S00-AAA, while trailers start at S000-TAA.
EzyPlates.
EzyPlates is administrated by the Department of Transport Infrastructure and Energy SA.
Since 1995, "Premium" registration plates can be purchased which are much more compact in size, in the format aa-nnna: the letter is usually repeated (e.g.: AA-nnna, BB-nnna, current series DD-nnna). These seem to follow the New South Wales Premium format, using black lettering on a white background on a noticeably slimmer plate. South Australian "Premium" registration plates feature black characters on a white base, and the letters "SA" down the side, in the same format as NSW "Premium" registration plates. As of 28 September 2009, there is a new addition to the premium range – white on black base, from XX-000A onwards.
Special purpose plates.
Government and police vehicles has SA Government plates in blue text on white background as S000·AQA (or previously XQA-000), with a Q as the second letter signifying "Queen" or representative of the government. Older systems were allocated SAA-000 to SZZ-999 to government services as well. The legend is embossed as SA Government.
Ambulances belonging to SA Ambulance Service have plates in the form AMB-nnn, however some vehicles now have standard SA Government plates due to leasing agreements with the State Government (Fleet SA).
Metropolitan taxis have plates with the word TAXI in a smaller size followed by three or four numbers, separated by the current tourism logo for South Australia – SA, A Brilliant Blend. More recently a new country taxi plate has been introduced in black on reflective yellow replacing general issue plates on SA country taxis. Other chauffeured vehicles have a different style plate with a blue outline.
Since September 2007, The heavy vehicle series commenced and the format used is SB·00·AB with the legend SA – HEAVY VEHICLE,the Trailers start at SY·00·AA
General issue.
No general issue SA registration plates (other than Government) are issued with the letter Q anywhere in the combination. The only exception is the series VPQ-nnn and WSQ-nnn – both of which were the first set issued by a new manufacturer.
Between 1981 and October 2008, all general issue SA plates contained the slogan "SA – The Festival State", for the Adelaide Festival of Arts. Between 1997 and October 2008, other slogans were available for an additional fee, including: South Australia – Gateway to the Outback; South Australia – The Defence State; South Australia – The Wine State; South Australia – the Creative State; South Australia – The Rose State; and South Australia – The Electronics State. All slogan plates are discontinued, as at October 2008.
