01Local context
The 2021 ABS QuickStats for the Newcastle local government area recorded 45,617 separate houses, representing 69.0% of occupied private dwellings. It also recorded 36.9% of occupied dwellings with two registered motor vehicles and 15.7% with three or more. Those dated measures do not describe every property in Wallsend, New Lambton, Charlestown or Maitland and do not measure garage-door demand.
They do support asking how many openings and vehicles are affected, whether a vehicle is trapped and whether another safe access point remains available. Newcastle also needs a structural-work branch that a generic NSW page cannot provide. City of Newcastle says parts of the local government area are affected by underground coal workings and that its mine-subsidence controls apply to a new building or structure, extension or structural alteration within a proclaimed Mine Subsidence District.
Some minor work can be exempt, so a campaign must not claim that every door repair or replacement needs Subsidence Advisory approval. It should ask whether the job is door-only or changes the opening or garage structure, collect the property location and route uncertain projects to an address-specific planning and subsidence check. City of Newcastle separately says a new garage requires consent through a complying development certificate or development application, with the applicable Housing Code and Newcastle Development Control Plan requirements.
02Campaign and claim checks
That is a different enquiry from replacing a door in an existing compliant opening. NSW minor-trade, electrical and residential-contract rules still depend on the actual work and value: fixed wiring cannot be bundled into an opener offer without the appropriate electrical authority, and structural or complete-garage work must be classified before contracting.
Meta Ads Guys has a published Sydney garage-door case study from a dated connected-account snapshot. It supports the niche in NSW but is not evidence of Newcastle inspections, repaired doors, approvals, installations, accepted quotes, sales or revenue.
