Open Word, and open a document. Go to the main menu across the top and Click on Tools. That will give a drop-down menu, and the fifth item is Language, which Choose. This will open another small window listing languages. You will see English(US) as the first language listed. But go down the list alphabetically, and you will come to English(Aus) - (Australian) - , and English(UK), which Choose.
