Heh, you could probably blame many of Perth's failures on the role of the mining industry there. Engineers have to be flown in from as far away as New Zealand to make up for the shortage, a flush city administration happy to double-down on pet projects, and so on. But, obviously these are all anecdotal, I just know from my time at a large civil engineering company that the failure rate appeared to be very low. Part of that is excellent risk management, but also long-term client relationships, clear and long established success criteria and a distinct lack of political meddling (once the project is underway, at least).
