Any light bulbs that are 240v and compatible?

other than Philips Hue I mean, they are way too pricey here in Australia…

Not sure how much cheaper they are, but Osram Lightify makes a version that should work:

$100 each here so even more than the Hue…

Check with Osram directly and see if there’s another Australian distributor, they’re intended to price below Philips:
