Chatting to my recruiter today and he told me that he was freaking out because he lives in a building in Southbank that was built about 20 years ago and after the earthquake the concrete in the basement of the building has started to crumble. He's moving out in a couple of weeks.
Apparently, post 1989, taller buildings in Melbourne have to be earthquake resistant, but some of those buildings in Southbank had pretty dodgy construction so it wouldn't surprise me if some of the concrete was sub-par.

Top End of Collins street
but Nauru house 80 Collin street 53 story finished in 1977 and 55 Collins street finished 1981 twin towers the ANZ tower and next door hotel towers
I have worked there and when went outside on the roof top of these buildings just noise and creaking the wind blowing on them makes wonder what it going to be like in an earth quake these were built .
i'm no good with heights so it just makes me uneasy thinking back about it now.
I am pretty certain those buildings would be OK in most earthquakes - they might not have been designed to withstand earthquakes, but they are designed to withstand wind, and with that height and known maximum winds in the area, I doubt there is any possibility of their falling. Moving, yes, and probably shed a bit of cladding, yes, but fall over? I doubt it.

I installed the lifts in 120 Collins and the amount that building swayed was amazing , sometimes it was nearly impossible to gauge the rails due to plumbline movement.

There were a couple of reasons, mostly to do with inadequate reinforcing or a change in construction method in the building itself.

I was aware of the "third floor issue" when I lived in Japan.
