The key difference is that strata titles allow only one scheme to be created on a single parcel of freehold land.
A strata titles scheme can be re-subdivided by changes to lot boundaries and common property; but does not include subdividing a lot to create another scheme.
Community titles allow the same land to be subdivided in a way that allows a lot in a community titles scheme to be subdivided to create another community titles scheme and in this way creates several individual schemes (community titles schemes) in a single community scheme. These community titles schemes may be building schemes (like strata) or land schemes (like survey strata).
Management of common property, scheme types, by-laws, planning requirements and the body corporate are also different between community titles schemes and strata titles schemes and further details on these differences are outlined in the Guide to community titles.
