If the tiles are fixed to an external wall, or the wall separating your apartment from the next one or a common area, then yes they’re fixable by the Owners Corporation.
Except if you live in a state (eg Victoria) where this can be incorrect.
In some states (eg Victoria), tiles on all lot interior walls are considered to be surface treatments (like paint) and are the owner’s responsibility.
In these matters, where you live in Australia, can make a difference!
