If it is a 60s building someone in the near future will renovate. If it involves structural changes it will need a DA. The council will ask for a copy of the fire certificate as part of the DA process.
In many blocks this is the trigger to start the fire assessment process.
I would bring this up with the committee. If you have a strata manager start with them. The strata manager would have no doubt already gone down the fire compliance path in other buildings. Yes it is a cost but it has to be done.
Good Luck!
