Watch out for common Americanisms.
Use the following:
- Organise and recognise (rather than organize and recognize)
- Colour, behaviour, (with a u) counselling and counsellor (two lls)
- Targeted and targeting (one t)
- Ageing (not aging)
- Wellbeing not well-being.
There are some exceptions, for example if you use:
- specific research-based terminology, for example self-actualizing.
- the title of an American or international organisation, company and so on, for example ABB Corporate Research Center, World Health Organization (although this is sometimes spelled Organisation in different publications)
- the title of a publication where the original spelling uses a US format.
Where there is no distinction between US and Australian but two ways to spell the same word, use one consistently.
