Q. Do we spell 'organisation' with a 'Z' or an 'S' in Australia?
This has been confusing me.
Some of your lecturers may prefer you to adjust your settings to Australian/British spelling which use the letter 'S' rather than American spelling which uses the letter 'Z'.
Whichever you use, make you are consistent across the assessment with either British-Australian or American. If you are still not sure which one to select always speak with your lecturer for further guidance.
