This group is about Microsoft Access (the desktop database.) People in the
Word group could probably help you better.
Suggestions:
1. Go to Regional Settings in the Windows Control Panel. Make sure your
default location is Australia.
2. In Word, select all (Ctrl + A), and choose Set Language on the Review tab
of the ribbon (Word 2007), or the Tools menu in previous versions.
3. In the Language dialog, choose "English (Australia)."
4. Click the Default button at the foot of the dialog. Answer Yes to the
question about making this the default language for all future documents
based on the Normal template.
(Note that this does not affect documents you have already created.)
