Hi Londonlady
Welcome to Poms in Oz.
I'm not sure about the English test - I don't know whether it is compulsory for everyone. Alan Collett (a Registered Migration Agent) has published a helpful article about it, though, which is here:

However, you will definitely not be required to take a Citizenship Test unless and until you apply for Australian Citizenship in due course. There is a 4 year waiting period now before people can even apply for Citizenship.
Meanwhile ptlabs (Peter) is another Registered Migration Agent who is also an expert on Australian Citizenship. He has published another helpful article about the Citizenship Test, which is here:
