In the cities, Sydney, Melbourne and Brisbane, the building blocks are getting smaller and the houses are getting bigger. Most back yards don't have access for a car, let alone a truck. Outer suburbs and rural areas have more room, but tend not to spend as much on tree maint or PHC.
The average suburban block was 1000 sq metres (1/4 acre), but most of these have been sub divided with a house at the rear or demolished and 5 or 6 villa homes built on the same site.
Also, many Sydney coastal areas are very steep which impedes access for machinery.
