How to research a property before buying in Australia

Work in this order. Each step tells you which questions the next one still has to answer. Planning names differ by state and territory: development application in New South Wales, Queensland and the ACT; planning permit in Victoria and Tasmania; development approval in South Australia and Western Australia; development permit in the Northern Territory.

1. Listing. Copy every specific claim: land size, bedrooms, “not flood affected”, “STCA”, a rent figure, a station, “subdividable”. Each claim is a hypothesis. See how to cross-check an agent’s claims.
2. Parcel. Official land area, lot shape and frontage come from the cadastre, not the advertisement. Districts shows the official parcel area beside the listing figure when both are loaded, and flags a material difference.
3. Transactions. This lot’s recorded sales, then comparable recorded sales. An asking price is marketing. See asking price and comparable sales.
4. Planning. Zone, overlays and any application recorded against this lot. Use the portal and scheme for that council. See zoning and this lot’s DA history.
5. Hazards. Flood and bushfire screening layers, then the instrument behind the name. A polygon is not a certificate. See flood and bushfire.
6. Nearby. Applications that change outlook, traffic, shadow or competing supply. Distance depends on the project type. See nearby DAs.
7. Building. Building and pest inspection, and a strata or body corporate search for units. No data product replaces this.
8. Title and contract. Easements, covenants, encumbrances and special conditions. A conveyancer or solicitor reads them. Vendor documents differ by state: NSW s10.7(2), Victorian s32, SA Form 1, Tasmanian s337. There is no single national certificate.
9. Rent. Advertised comparables for the same class, labelled as advertised. Even if you plan to live there. See achievable rent.
10. Suburb. Census, ERP, sale medians and pipeline on separate dated lines. See how to research a suburb.
11. Unresolved. Every unknown is a condition, a professional job, or a risk you are choosing to carry. See how to verify.

A research product can assemble desktop layers. It cannot sign an inspection report or a contract review. Write the owner on each line so a loaded map is not mistaken for a closed file.

Labelled illustration. A listing says 812 square metres, “not flood affected”, “dual occupancy STCA”, and a rent of $750 a week. The Districts page, where loaded, shows officialParcelArea 743, zone.code R2 and zone.name Low Density Residential, a flood-planning overlay with materiality “affects” and floodShare 0.18, and development optionality as a Districts-derived screen that the zone contemplates dual occupancy subject to standards. thisLotDa is not loaded. Statutory land value is not loaded. Three advertised two-bedroom houses in the same suburb sit between $620 and $680 a week.

Write in the file: listing area does not match the parcel; the flood claim is contradicted by a loaded overlay on 18 per cent of the lot; STCA is a reminder that approval is still required; $750 is above the three advertised comps; this-lot history and statutory value are unknown. None of those lines is a decision to walk away. Each one is a named next step: parcel versus listing, council flood information plus an insurer, the scheme standards plus a planner if you need the second dwelling, and a rent range from current listings.

These mistakes close a question that is still open.

• Treating the listing as research. It is the thing being tested.
• Using the suburb median as the property’s value or rent.
• Reading a blank flood or DA field as clear. If the layer was not queried, the answer is unknown.
• Confusing a zone that contemplates a use with an approval.
• Stopping when the desktop looked tidy. Inspections and title are not optional because the map was quiet.
• Claiming that most problems after purchase were knowable. Some never appear in a public layer.

It does not establish that the building is sound, that works were approved, that the title is clean, or that a lender will fund the price. It does not establish that an overlay will be acceptable to an insurer. Districts cannot see the contract, the strata roll or the inside of the dwelling. Where a planning register or flood layer is not loaded for that council, the check stays unknown. That gap is a limit of the evidence, not a finding that the lot is clear.

A property page runs the same ten checks: optionality, nearby pipeline, achievable rent, rental supply pressure, price explanation, lot-level flood, catalyst exposure, this-lot DA history, statutory land value versus ask, and net yield. Each check is completed from a named source or shown as unknown with the reason. Research coverage counts how many slots had evidence. It is not a score of the property. See the method page for the product stack, which is a different job from this workflow.

Take material findings to the person or document that can close them. Planning and overlays: the council or state authority, and the certificate or vendor statement used in that state. Flood: council information and your insurer. Title and contract: your conveyancer. Building: a licensed inspector. Value: a registered valuer if the decision needs one. Finance: your lender. See how to verify. If a line is still unknown on the day you sign, write that you are carrying it.
