Bunnings currently has them for $38.95 if you want to try and price beat. (I'm not sure how this works when buying multiple Items)
I grabbed 4 of these recently and they have been great so far.
Simple to swap current downlights, I didn't even need to get in the roof, just pull out the current ones from below and the power point is right there in the hole.
App / Google / Siri control for basic on off / dimming.
You can set two differnt modes to be controlled by the light switch on the wall (flick them on and off twice to change to second default mode)
Connect directly to your Wifi, no extra bridge or anything required (Fine if you have a quality router, if you have a $50 router from 10 years ago it might struggle if you add 25 new devices)
They also sell a stand alone remote for $16
For those in the Phillips Hue Exosystem or want to go for the top of the range ones.
