Trying to work out what’s actually possible on a development site can be an absolute nightmare. So in this episode, we’re joined by Will Sullivan from PropCode to talk about how AI might be able to help. We dig into how tech is being used to speed up the research process, reduce the need to spend hours on council websites (or pay $250 an hour to a planner), and pull together planning rules that are otherwise hidden across PDFs, maps, and inconsistent formats.

We talk through how PropCode works, what it can do—and just as importantly, where it stops. It’s not replacing town planners or council staff, but it can give homeowners, investors, and developers a clearer sense of what they’re working with before diving in too deep or spending money on the wrong site.

We also unpack the major planning reforms in New South Wales and how they’re set to impact development potential around train stations and local centres. Will explains why not every site will benefit equally, and why developers still have to think hard about feasibility—because just being zoned for six stories doesn’t automatically mean a windfall.

If you’re buying, selling, renovating, or developing property in NSW, or just want to understand how AI fits into the planning space, this is a great one to tune in to. We’ve also included a link to PropCode’s free tool in the show notes—it’s worth checking out.
