I disagree. One of the key components of success for modern stadiums is for them to be located either within, or as close to as possible, a bustling CBD (see Adelaide Oval, Marvel Stadium in Melbourne, Optus Stadium in Perth and the new stadium in Townsville). Public transport options as well as bars, cafés and restaurants all need to be within strolling distance of the punter.
The last thing you want is a Bruce Stadium situation where the punters are having to drive out to a paddock in the middle of nowhere and have nothing else to do besides drive home after the game has finished.
Up until COVID-19, and probably beyond, Parramatta CBD is booming. It was absolutely the correct decision to locate Bankwest Stadium within Sydney's second hub.
