I’ve had a quick scan of Qld strata law and I can’t findthe clauses I expected, meaning the Body Corporate can enter lot property to undertake work – but that doesn’t mean they’re not there.
In other states, theses clauses exist, but that doesn’t mean they have the right to just wander in and set up their gear. They need your permission and if you refuse, they have to get orders from the state tribunal. I would be surprised if something like this didn’t exist in QLD.
Assuming for a moment it did, you could talk to your management and tell them that they are going to have to come up with some sort of compensation or you are going to block access every time they want to use your lot and they will have to seek orders at QCAT.
What form that compensation might take is up to you – but it should also be allied to strict time limits or you might find ladders and scaffolding parked there permanently.
Meanwhile, I suggest you contact the Unit Owners Association Queensland and/or the state government’s advice page HERE if only to find out exactly what your rights are.
