    After the spate of roof-space fires that were reported as being related to insulation materials and un-shielded downlights, the various State/Territory Fire Authorities produced some guidelines; HERE is the NSW one.

    The only requirement linking air conditioning ducting with fire safety that I’m aware of relates to the control of smoke; that is to prevent it from being distributed from the fire source to other areas within a building via the fan-forced ducting. Have a look as Australian Standard 16681.

    Slightly off-topic, but take into consideration that some air-conditioning components and part of downlight fittings are often within the common property (roof-space), and unless O/Cs have a Special By-Law covering the responsibility for maintenance, repairs, and replacements of those components, then they’re responsible for that by default – even if those components service an individual Lot.
