First time posting a deal. I've been eyeing a Nest Protect for a while now but not willing to spend so much on one. JB Hifi selling them for $118.30 today! Another 5% off if you can find one at Officeworks.
Wired one here

Comes with six Energizer Ultimate Lithium included as well.
Anyway there are a lot of comments about whether it is compliant. I am not an expert on this but mine says this on the unit.

I bought 4 Xiaomi smoke detectors for the same price. They have the same functionality + can integrate into the house alarm system.
