Writing Australian dollars correctly involves more than just placing a dollar sign in front of a number. It requires an understanding of the specific conventions that govern currency notation in Australia, ensuring clarity and professionalism in any financial document. This guide breaks down the rules for individuals and businesses who need to present amounts accurately, whether they are drafting an invoice, filling out a form, or writing a contract.
The Symbol and the Code
The primary symbol for the Australian dollar is the dollar sign ($), which is shared with several other currencies including the US and Canadian dollars. To distinguish it specifically, the ISO 4217 currency code is AUD. When absolute precision is required, such as in international banking or detailed financial reports, using "AUD" is the standard practice. For most everyday writing within Australia, however, the $ symbol is sufficient provided the context makes it clear that the amount is in Australian currency.
Basic Formatting Rules
There is no space between the dollar sign and the number it precedes. This rule applies to both figures and words when representing currency. The correct format is $100 or $1,550.00, not $ 100 or S 1,550.00. When writing out amounts in words, the term "dollars" should follow the numeric figure in full, and the amount should be written in words on the same line to prevent tampering. For example, on a cheque, you would write "One thousand five hundred and fifty dollars and 00/100" for $1,550.00.
Decimals and Cents
For amounts that include cents, the decimal point is used, followed by two decimal places. Commas are used as thousands separators in figures to improve readability. It is important to avoid using spaces as separators, as this can cause confusion in digital processing. The standard representation is always $1,000.00, where the comma separates thousands and the zeros after the decimal represent cents.
Words or Figures?
In formal legal and financial documents, amounts are typically written in both figures and words. The figure is placed on the left side of the line, and the words are placed on the line below or above, indented, to ensure they cannot be easily altered. When writing words, use lowercase letters and include the word "and" to represent the decimal point. For instance, $1,250.50 is written as "one thousand two hundred and fifty dollars and 50/100".
Contextual Considerations
In digital contexts such as websites, emails, and text messages, simply using "$50" is perfectly acceptable and widely understood. However, in contexts where the audience might be international, specifying "AUD" can prevent misunderstandings. For academic or technical writing, consistency is key; once you choose a format, you should apply it uniformly throughout the document to maintain a professional standard.
Common Mistakes to Avoid
One of the most frequent errors is placing a space between the symbol and the number. Another is using the wrong currency symbol, such as writing USD or EUR when you mean AUD. It is also incorrect to use the cent symbol (¢) for the Australian dollar; the dollar sign ($) represents the whole unit. Avoid abbreviating "dollars" as "dols" in formal writing, as this can appear unprofessional.
Regional Variations and History
Australia transitioned to the decimal currency system in 1966, replacing the Australian pound with the Australian dollar. Since then, the notation has remained consistent with international standards for decimal currencies. While slang terms like "buck" or "dough" are common in casual conversation, written documentation should always use the formal terms to ensure clarity and adherence to financial regulations.
