  • 13 - The waterless urinal that now needs a flush

    In this episode of Developing WA, Kai and Russell go through the 2025 AS 3500 changes and what they actually mean on site. Parts one, two and four have been mandatory in WA since 1 May 2026, and Russell walks through the ones people are most likely to get caught by.

    You'll hear what the new flexible hose classes mean for the flexi sitting under your sink, why a waterless urinal can now need a flushing device fitted to it, and why stormwater is the only unregulated section of AS 3500 in WA — the section behind 95% of the disputes Russell gets called into.

  • 12 - Who's Actually to Blame When a Building Fails

    In this episode of Developing WA, Kai Armstrong sits down with Russell to dive into all things forensics. Russell doesn't just design hydraulic systems, he gets called in as an expert witness when they fail and somebody ends up in court, usually by a lawyer acting for their client or a loss adjuster at an insurance company.

    You'll hear why roof plumbing is no longer a licensed trade in WA, who actually carries the blame when a building fails and who walks away clean, and the dispute where both sides spent $800,000 each on legal fees to argue about a $600,000 repair.

  • 11 - What WA's Building Boom Is Hiding

    In today's episode, Kai joins Russell to talk about what WA's building boom is doing to construction quality.

    You'll hear why WA's shift to desalinated water is quietly wearing out plastic pipes years before they should fail, why the code covering box gutters and storm water is the one chapter of the plumbing standard nobody actually regulates, and why Russell thinks the industry needs to slow down instead of racing every project to 100 percent.

  • 10 - Lessons from 30 years in manufacturing, with Darren Chatfield

    In today's episode, Russell sits down with Darren Chatfield from Spectrum Plastics for an honest chat about the reality of running a manufacturing business. 

    You'll hear why raw material prices have jumped 50 to 100% in a matter of months and why Darren says it's a bigger challenge than COVID ever was, why he believes indecision is a death trap when the business is yours to run, and the simple driveway rule Darren has used for three decades to stop work following him home.

  • 9 - Why developers have stopped building, with Russell Green

    In today' s episode, Russell is back in the guest seat with Kai for part two of their conversation, going deeper into the realities of running a consultancy, leading a growing team, and where the WA property market is heading.

    You'll hear why Russell designs every project thinking like a property investor instead of a consultant, the kind of leader Russell decided he didn't want to be, and what Russell would say to a Gen Z buyer who reckons it's too hard to get on the property ladder.
