Thanks all for your warm welcome, unfortunately on this topic neither I, nor our management, nor the management of any of the big annexe manufacturers with whom we have had lengthy discussions (tebbs, Australia wide, kakadu etc) can currently claim to be experts on this subject!!!
There is talk of it being retrospective. This along with a number of other questions was put to the relevant authority but as yet nothing as come back. The amount of ambiguity in all of this is quite silly, so much so that a couple of annexe reseller boycott the QLD show for fear of misinterpretation costing them down the track. Like you we figured the act applies solely to hard stand annexes until they clarified otherwise. Even to the point they said a dull mesh annexe will not be allowed without ensuring the flow rates of the mesh do not breach the definition of an outside area.
As for why a stove is okay but other appliances are not, it's only gas flues that are the issue. A stoves element requires it to have been approved for indoor use (I guess this comes down to flow rates) a fridge or HWS flue has not. I never said the fridge could be vented into the van just that is must not be vented into an annexe. Must be vented out of the van and away from the annexe.
The reason only low vents are required in the annexe is that it just needs to replicate the low vent in the van (door) that is now inside the annexe. The top vent inside the van still vents externally and is still sufficient.
The soft floor camper trailer guys have just been given the great news too but so far no one has been to vocal from that side surprisingly.
