Steps for installing another dictionary...
1) From the Word menu, choose Tools - Options.
2) Then click the "Spelling & Grammar" tab.
3) Click Dictionaries, then opposite "Languages", select English (Australian).
4) Then click "Add". At this point, you'll need to "browse" and locate the folder where the dictionaries are located. I'm sorry I can't be specific here, but I expect it will require the use of your installation CD.
Another (less desirable) option is to...
1) type a list of the main words that cause a conflict - like the list you supplied.
2) right-click on each word, and choose "Add".
This will add these words to your dictionary, and they therefore won't show up as misspelled words in the future.
Hope this helps.
