In short: Downlights without the clearance they require, recorded on an Austral handover.

The conflict

Insulation wants to be continuous. Certain downlights want air around them. Where the two meet, the fitting wins, because the alternative is heat with nowhere to go.

What we recorded

Downlights on an Austral home with insulation hard against them, in more than one location.

Why it gets missed

The insulation goes in from above and the lights go in from below, usually on different days by different trades, and neither sees the other's work.

What the fix looks like

Clearance maintained, or fittings rated for insulation contact. Both are ordinary, and both are the builder's item at handover.

The related item

Switches and lights inside the zones around a bath or basin, which we also recorded here and which is reported the same way.

FAQ

Questions Austral owners ask about this

Is this really a safety item?

Yes, and we report it as one rather than burying it in the general list.

Can I just pull the insulation back myself?

You could, but at handover it is the builder's obligation and should be closed out as one.

What are the wet area zones?

Defined distances around a bath or basin within which fittings are restricted. The report states the measurement against the requirement.

Would an electrician have signed this off?

The certificate covers the electrical work. Insulation placed afterwards by another trade is exactly how this arises.
