Unless its a real emergency the OC needs an order of the court to enter a property
In an extreme emergency ie a fire the OC can enter without a court order. The only damage I can contemplate is a broken door. As the door is OC property, they have to repair it at their cost. But thats going tobethe least of the problems.
Maybe you can be more specific about the type of damage you are thinking of.
If an OC is granted entry to a property it needs to take reasonable precautions not to cause any damage to owner property. However how one proves the OC damaged owner property may be harder to prove.
NCAT is a civil court, so the standard of proof is “on the balance of probabilities”. Unless you can show recent photos of undamaged property, proving such a case, even with such a low threshold, is difficult.
