Who must comply with AASB S1 (general sustainability) disclosures — voluntary today, mandatory?
The applicability test for AASB S1 (general sustainability) disclosures — voluntary today, mandatory pending (ASIC), computed across 35 industries, 9 business structures and 6 size bands.
Short answer: Only if
Applies only if you choose to report voluntarily under AASB S1. Whether it applies turns on a fact that no industry, structure or size settles on its own.
What the obligation is
Companion to AASB S2 (climate). Currently voluntary in AU; ISSB pathway suggests phased mandatory.
AASB S1 mirrors ISSB IFRS S1 for general sustainability-related financial information beyond climate. Currently voluntary in Australia; Treasury consultation suggests phased introduction following ASRS climate-only commencement. Boards should align voluntary preparation with eventual mandatory.
The applicability test
Applies only if you choose to report voluntarily under AASB S1. Whether it applies turns on a fact that no industry, structure or size settles on its own.
How the regulator frames it: Voluntary today; Group 1 entities should prepare for phased mandatory.
What triggers it: Voluntary commitment; future mandatory commencement.
Jurisdiction: Commonwealth law, so the test is the same in every state and territory.
Which industries are in or out
Outcome across the 35 industries Rules Mate maps (35 of 35: only if a further fact applies).
The answer is the same in every industry: only if a further fact applies. Industry does not change who must comply.

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 real estate agents with 100–499 employees, turnover $10M–$100M: check whether it applies. applies only if you choose to report voluntarily under AASB S1.
- Pty Ltd company in real estate agents with 500+ employees, turnover $100M–$1B: check whether it applies. applies only if you choose to report voluntarily under AASB S1.
Answers that bring it into scope
Starting from a small or large professional services company that does not otherwise meet the test, each of these single facts changes the engine's answer:
- The business is regulated by APRA: it becomes worth checking, because it applies only if you choose to report voluntarily under AASB S1.
When you need to check further
The engine shows this obligation as "check whether this applies" when a business has the ASRS size tests (revenue ≥ $50M, assets ≥ $25M, 100+ employees — 2 of 3) or asrs maybe. It then applies only if you choose to report voluntarily under AASB S1. That fact is not something Rules Mate can infer from industry, structure or size.
