OK. Let me state I have a NSW electricians and was a certified practicing engineer.
Lets get over the safety issue in this case. If it’s old VIR cable then it could be perished and need replacement.
A 32 amp capacity is adequate for such a small apartment. The Australian standard for wiring says exactly how to calculate what we call the maximum demand. Having done a number of such calculations and have seen larger apartments work ok with 32A.
If the installation is currently done correctly, then the fuses or circuit breakers will prevent fire etc in the installation.
Unless you have someone on the committee who has a building background and takes an interest in the infrastructure of the building, I doubt anyone will know the state of the electrical system.
The approach suggested by nemesis is reasonable. If you can’t interest other owners or the committee, you may have to go this yourself. You never know, the engineer may say it all needs replacing and the OC may pay.
With my qualifications I did a report at my daughters complex regarding an old switchboard. On the basis of my report the OC agreed to replace part of the switchboard.
What you propose is something that owners of old buildings should consider. As living styles change, people expect lots of power to be available. Convince the other owners that it will improve their lots value and get them on board.
