Flinders Street Station here in Melbourne.
Manchester Unity Building. Beautiful art-deco style.
And can't forget the Melbourne Cricket Ground.
I thought it was officially called the hive, its a clever well designed building (the big concrete structure in front houses a pump that uses water from the river for cooling the building) it just looks horrific, I don't think its just down to the cladding either, the sports hall the other side of the river is ok
Also, this is the beehive. The Wellington Parliament House in New Zealand.
