I don’t think that’s the case, because Sydney is very big with the city, Hornsby, Parramatta, Penrith, Campbelltown, Richmond. I don’t think it would include The Central coast
It looks to me like the Sydney measurement is the Greater Capital City Area compared to everywhere else which is the Metropolitan Area; and Sydney's includes the Central Coast. Doesn't really change the quiz though because Sydney will still presumably be number one (until we find out officially in June)
Nice quiz as well!
