Hi
@Arkraider I have investigated this heavily myself lately because of potential ramifications that it may have had with insurance etc. Firstly you won't be fined, it is only the manufacturers of the caravans or annexes that can be fined or prosecuted if they were to not comply and there was an accident or fire that resulted in the non compliance.
From an insurance perspective anything manufactured prior to April 2014 is not required to comply to the new regs, it is only caravans or annexes manufactured and fitted after this date.
I spoke with a senior person from Jayco and the compliance to the new reg and the changing of layouts was just that, it was so they complied. For an actual accident to happen would require a number of extreme series of events to all occur at the same time. The new regs have come about not from caravans and annexes but from the unfortunate deaths of the two kids and the wall heater in a home in 2010.
This article explains that its the manufacturers that face the fine of $2,000 per offence not the consumer.

Hope this helps clear up any concerns you had. By the way I just happen to be selling my 17.56.1 with annex and a heap of other extras.
