Delora

Knowledge base

Legal framework

The primary valuation and sale-of-land/conveyancing legislation behind property law in each of Australia's 8 states and territories — who administers land valuations, and what statute governs the sale contract. Every figure is drawn from this graph of claims, each traced to a specific, actually-fetched government or regulator source. This page is generated directly from that graph, not maintained separately from it. See the full knowledge base for other subjects.

How this works

Delora fetches primary sources — government departments, regulators and authoritative registers — archives them with a content hash, and extracts specific, citable claims from them. Guide pages and tools read from these claims rather than having figures typed directly into prose, so every figure a reader sees links back to where it came from and when it was last verified. A monitor re-fetches each source and flags genuine content changes for review — nothing is republished automatically.
