Sooz said - "noticed that the Australian team sang their National anthem with great passion while the All Blacks stood stony faced. Is this significant?"

Yes it is - NZ 's laws have to respect the Treaty (between the British colonists & Maori), so half the National Anthem is sung in Maori - unfortunately few people (Maori/Pakeha) know the words!

Well done Oz - a hard game well played....but then your population is huge compared to NZ!!!....some of the "little countries" (Wales, Pacific Islands) can be very proud of themselves.
