In fact things like attic hatches are supposed to be sealed ane so even though seen the inspector is not allowed in the attic. (Unless there is other evedence of a problem, though they need to repair the seal in that case.
It's that something regional for specific access type? My Victorian houses always had the roof hatch accessible - it's just another storage area and needs to be available if you want to rewire something.
Nonsense. Every house built in Victoria has an accessible hatch to the roof space. The hatches are not sealed either, it's just a lid resting over the opening, which can be pushed upward. Some have hinges, etc.
