It seems that most people want to live in cities or their surrounding urban outskirts.

Australia is a fantastic vast land with only a small percentage of it that has been urbanized.

There was a time when Montreal had taller buildings than Melbourne, but that was a long time ago. That's because Melbourne isn't vertically limited like Montreal is. 1000_de_La_Gauchetiere is the only office tower in Montreal that has been permitted to have more than 50 floors. Given the strict height restrictions, Montreal might not permit any building to rival the Rialto_Towers for a while yet.
It seems that Australia isn't waiting for Canada to catch up, by the time that Australia has its 3rd building consisting of at least 100 floors, Canada will still have no 100 story buildings.

The CN_Tower like the Sydney_Tower and the Sky_Tower_(Auckland), aren't office or residential towers.
The Harbour_Centre (stump) in Vancouver is a joke. The office portion of the building wasn't even allowed to have a 30th floor. Even the top of the antenna had to be less than a 3rd of the height of the CN Tower, because of the strict height limitations in Vancouver.
The John_Hancock_Center in late 1960s Chicago, was the first office and residential tower to have a 100 floors, outside of NYC. Australia just might eventually have a couple of buildings taller than the John_Hancock_Center.
