Many investors see property development as the natural “next step” — a faster way to manufacture growth and build equity. The reality is far less straightforward: most development sites that can be built on simply don’t make money.
Rob Flux, founder of the Property Development Network, joins us to break down what really changes when you move from buy-and-hold to small-scale development. We explore why 90% of developable sites aren’t profitable, how feasibility is often misunderstood, and why “profit on cost” — not hype — should drive your decisions. Rob explains the importance of site selection, overlays and constraints, demographic targeting, and why solving the right problems is what developers actually get paid for.
We also dive into the practical realities: commercial vs residential funding, entity structuring mistakes, contingency planning, holding costs, and the psychological traps that come with early success. Is development just leveraged investing — or is it an entirely different career path? And in a market facing a 1.2 million home shortfall, does that make development easier… or just more competitive?
If you’ve ever considered “graduating” into development, this episode is your reality check. Development can accelerate wealth — but only if you treat it with the seriousness it demands. Otherwise, it’s just an expensive lesson.

About the Guest
Rob Flux is a property developer, mentor, and founder of the Property Development Network (PDN), Australia’s largest community of active small-to-medium developers. With monthly meetups across Brisbane, Sydney, Melbourne, Adelaide, and Perth, PDN has become a leading education and mastermind platform for aspiring and experienced developers alike.
Rob began investing at 18 and achieved financial independence by 38 — before a divorce forced him to rebuild from scratch. His first development deal delivered $1 million in profit, allowing him to leave his IT career and focus on development full time. Since then, he has refined his approach into a structured 7 Step Property Development Formula and continues to complete six- and seven-figure projects using creative acquisition and funding strategies.
Beyond education, Rob serves on government advisory panels contributing to housing policy and planning reform across Australia. His mission is clear: to help 1,000 people achieve financial freedom by 2030 through smarter, more strategic property development.
