I was under the impression (possibly wrong) that you cannot hold more than 2 passports if one of them is Australian.
I have UK as well and was told I could only hold 2 passports - have I been given the wrong info?
As I understand it depends on how you gained AUS citizenship. I was born in the UK and I am a "naturalized" AUS. I lived in Canada for an extended period and married a Canadian. I hold AUS and UK passports, and I am a CAN resident.
I am eligible to apply for CAN citizenship (and therefore passport), however the AUS consulate advised me that if I did apply for CAN citizenship I would lose my AUS citizenship since I had "acquired" it - i.e. not by birth. This was too big a price to pay!:shock:
You cannot lose your AUS birth citizenship, so it may be viewed differently by other countries as you apply for a third citizenship and then passport.
