But when the codes were developing Sydney was much smaller, centred on the harbour and did not have the advantage of modern transport making many areas accessible to the common man. In Melbourne on the other hand you could put a cricket pitch in just about anywhere. Draw a 5k radius around both city centres and see how many pitches come up.That's pretty much BS. Sydney is a huge city geographically and there are many cricket pitches. Historically pitches were built as well as ovals.
Now it is very expensive to find the land for new ovals, though a great number of ovals have been created in recent times
I'm not suggesting it was a defining factor, just a contributor.
