We use Australian spelling, which is often different to American or British. Some common examples are listed here, but if you are unsure check the Macquarie Dictionary.
|✔||~ise: e.g. recognise, finalise, organise|
|~ize: e.g. recognize, finalize, organize|
|✔||~our: e.g. colour, labour|
|✖||~or: color, labor|
|✔||~ement: judgement, acknowledgement|
|✖||~ment: judgment, acknowledgment|
Check your spellcheck.
|TIP||You may need to set the language in Microsoft Word to English (Australian) to stop it automatically changing your words to US spelling.|
If you are referring to a specific organisation or publication, or using a direct quote, always use the original spelling.
