Abbreviations are shortened words. They can hinder people’s understanding, so they have limited uses.
Limit the use of abbreviations
Abbreviations contain the first single letter or first few letters of a word. They don’t include the last letter of a word.
Abbreviations are generally not good for readability and can be misunderstood. Avoid using them in general text where possible.

Abbreviations are useful in very limited circumstances:
in a table or chart, where space is unavailable for the full form of the word – provide a note under the table or chart giving the full form
when using ‘cont’ to show continuing text in another part of content (for example, on another page of a print newsletter) – the full form of the word is more helpful where space allows.
Semi-formal and informal content uses abbreviations more often. Use abbreviations only if users will understand what they mean. If there’s any doubt, define the abbreviation on first use.
Avoid using abbreviations in any public-facing content.
Avoid (or explain) unusual words, phrases, idioms and so on.

The digital edition recommends avoiding use of abbreviations in general text, and in any public-facing content. It follows the Content Guide’s advice to avoid using Latin shortened forms.
The digital edition lists common shortened forms and provides advice on the limited circumstances where they could be used and how to punctuate them.
This is a departure from advice in the sixth edition, which listed ‘thoroughly anglicised’ shortened forms used regularly in publications. It did not explicitly warn against their use. The sixth edition recommended against using ‘i.e.’, ‘e.g.’ and ‘etc.’ in paragraph text and in formal content.
The digital edition removes the sixth edition requirement to use full stops with non-Latin abbreviations. Exceptions to this rule are:
- Latin shortened forms (including for the formal names of plants and animals)
- the abbreviation for ‘no date’ (n.d.) used in referencing and citation.
The new general rule is supported by corpus information checked with the Australian National Dictionary Centre. It is consistent with the recommendation to use minimal punctuation. The removal of full stops affects style for abbreviations of:
