Comes in black as well as white. Note that these are the battery variants not the wired ones.
The same model is selling at $329 at Amazon, JB, Harveys etc.
Seems like a good deal and might be a glitch in the system from where Bunnings was matching Amazon's prime day deals.
Yes, it's subscription based.
I'm personally still on the fence since my house is drowning in Google assistant products but haven't seen any NEST camera deals lately and the reviews seem to have the Ring cameras slightly above the Nest and possibly on par with the Arlo 2.
Try price beat at Officeworks if you have one near you.
Was same price on amazon AU yesterday
