I've built a site that's a guide to the government's home insulation rebate programme. My aim is to provide a fairly quick and simple guide, given that the government site is all full of legalese like "the Owner-Occupier or Beneficial Owner of the dwelling" and so not the easiest thing to read. Most of the other information is from suppliers, so can hardly be thought of as impartial.
I'm also looking to target specific topics of information that are underserved but have a large ecosystem of Google AdSense advertisers, to see what kind of returns you can expect from it. Given how targetted this can be, it's looking pretty good so far.
So check out Insulation Rebate Australia if you want to learn about the rebate.
