Who must comply with Northern Territory Aboriginal Sacred Sites Act 1989 — Authority Certificate?
The applicability test for Northern Territory Aboriginal Sacred Sites Act 1989 — Authority Certificate, computed across 35 industries, 9 business structures and 6 size bands.
Short answer: Only if
Applies only if your activity disturbs land that may contain Aboriginal cultural heritage or is subject to native title. Whether it applies turns on a fact that no industry, structure or size settles on its own.
What the obligation is
Use of land that may affect a sacred site in the NT requires an Authority Certificate from AAPA.
The Northern Territory Aboriginal Sacred Sites Act 1989 makes it an offence to enter or remain on, carry out work on, use or desecrate a sacred site in the NT. The Aboriginal Areas Protection Authority receives applications for an Authority Certificate (s 19B), consults the custodians and, on request, holds a conference between the applicant and custodians within 60 days. Under s 22 it issues a certificate where it is satisfied the work or land use can proceed without a substantive risk of damage to or interference with a sacred site, or where the custodians and applicant have reached agreement. The certificate describes where work may and may not be done and any conditions, and carrying out work in accordance with it is a defence to the s 34 work offence. The Act also provides for enforceable undertakings and enforcement orders (ss 39B-39H).
The applicability test
Applies only if your activity disturbs land that may contain Aboriginal cultural heritage or is subject to native title. Whether it applies turns on a fact that no industry, structure or size settles on its own.
How the regulator frames it: Any person or body corporate proposing to carry out work on or use land in the Northern Territory where a sacred site may be on or near the land: developers, miners and explorers, pastoral lessees, infrastructure and utility proponents, and government agencies (the Act binds the Crown, s 4).
What triggers it: Proposing work on, or a use of, land in the NT that could damage or interfere with a sacred site, or needing to enter a sacred site other than under the Act or the Land Rights Act.
Jurisdiction: Northern Territory law only. A business with no operations in NT is outside it, whatever the rest of the test says.
Which industries are in or out
Outcome across the 35 industries Rules Mate maps (3 of 35: only if a further fact applies; 32 of 35: no).
| Industry | Answer |
|---|---|
| Construction (residential & commercial) | Only if a further fact applies |
| Agriculture, forestry & fishing | Only if a further fact applies |
| Mining & resources | Only if a further fact applies |
| No | 32 other industries |
Business structure and size
Structure does not change the answer in the 3 industries it can reach: for every structure the answer is "only if a further fact applies".
Size does not change the answer in the 3 industries it can reach: at every size band the answer is "only if a further fact applies".
Worked examples
Each line is one run of the Rules Mate applicability engine for a single business profile, with the reason the engine gives:
- Pty Ltd company in real estate agents with 6–19 employees, turnover $1M–$3M: does not apply. Requires a trigger outside this questionnaire.
- Pty Ltd company in construction (residential & commercial) with 6–19 employees, turnover $1M–$3M: check whether it applies. applies only if your activity disturbs land that may contain Aboriginal cultural heritage or is subject to native title.
When you need to check further
The engine shows this obligation as "check whether this applies" when a business has industry: Mining & resources / Construction (residential & commercial) / Agriculture, forestry & fishing. It then applies only if your activity disturbs land that may contain Aboriginal cultural heritage or is subject to native title. That fact is not something Rules Mate can infer from industry, structure or size.
