I wouldn't call them exactly same. Your city is more circular like the sun with freeways shooting out like sun's rays (how poetic), meaning your commuting times are shorter as you are all closer to the CBD (relative to Sydney). Sydney being where it is, is biased towards to East. To buy land we have to go further and further out west and north west and still commute to Sydney CBD for work. A lot of employers have relocated to Parramatta, Homebush and Norwest even but long way to go.
