NCAT cases are usually internal to a scheme — by-laws, levies, repairs, access to records. Court cases usually involve builders or insurers over defects, because those claims exceed the tribunal's jurisdiction. A per-1,000-lot rate isn't shown: Double Bay has 2,261 lots, small enough that a single litigious building would move it several-fold. These are published decisions only — most strata disputes settle or are resolved without a judgment, so this is a floor, not a count. See the Double Bay suburb profile.
