This would be tricky in any case but the fact that it’s company title complicates things even further.
In company title, you may not have the same rights as in strata so your relationship is really with the landlords who are obliged to ensure the property is properly maintained.
I would send them a polite note asking for compensation but informing them that they in turn are probably entitled to claim that amount from the building’s board (most likely via their insurance) and you will support them in that, if need be.
Explain that you don’t blame the landlord but there is a chain of responsibility and they are the next link for you.
If that fails you can apply to the CTTT for compensation on the grounds that the landlord or their agent failed to properly maintain the property (or make sure the Company board did so).
You’ll find a Tenants Union factsheet on that HERE.
And I wouldn’t worry about the new owners too much – this is a claim against the previous landlord and it doesn’t affect them
