Forecast by mesh block — modelled outlook within 1 km (by gnaf_id) (beta)
/v1/properties/{gnaf_id}/mesh-blocks/forecast20¢ per callBeta. The figures behind this topic have not been validated against an independent source, so it is not sold at the same confidence as the other mesh-block topics. Every response says beta: true and carries a beta_notice.
What's the outlook? Modelled forecasts for every mesh block around the property: owner-occupation in 2026, capital growth, the chance of a rezoning within five years, and future building height.
One entry per mesh block within 1,000 m of the property under mesh_blocks, nearest first, each with its mb_code, distance_m, population and dwellings. Blocks across suburb lines are included. Values only — the polygons come from /properties/{gnaf_id}/context/mesh-blocks.
Every field carries provenance — measured (at this block), measured_wider_area (measured for the SA1 or postcode and repeated on every block in it), estimate (our model) or not_recorded (not labelled yet) — plus how, one sentence on how the number was arrived at (empty when not_recorded).

About this data
What this is
Our modelled outlook for the blocks around one address (beta): for each mesh block within 1 km, forecast capital growth, owner-occupation in 2026, the chance of a rezoning within five years, and future building height.
What people use it for
- Investors: compare the expected growth of blocks within walking distance of each other.
- Developers: screen for blocks where rezoning or taller buildings are more likely.
- Analysts: a block-level input alongside suburb forecasts.
Coverage
Mesh blocks nationwide (about 368,000). The 1 km radius crosses suburb lines. A field is null where we hold nothing for that block.
Tips
Every field is our estimate, and many blocks have no forecast (null). For the property's own street use /v1/properties/{gnaf_id}/street/profile. Check provenance before quoting a field. Whole suburb: /v1/suburbs/{suburb_name}/mesh-blocks/forecast. Polygons: /v1/properties/{gnaf_id}/context/mesh-blocks, joined on mb_code.
