ASIC states that reporting entities must lodge their sustainability report and the auditor’s report on the sustainability report with ASIC under section 319 of the Corporations Act.
The ASIC lodgement page states the timing is within three months after year-end for disclosing entities, registered schemes and registrable superannuation entities, and within four months for other reporting entities.
ASIC’s sustainability reporting overview makes clear that the annual reporting package now includes both the sustainability report and the auditor’s report on the sustainability report.
That makes control design and documentation materially more important. The reporting workflow has to support challenge, substantiation, and review, not only disclosure drafting.
ASIC has published specific material on modified liability settings and has said it will take a pragmatic and proportionate approach during the transition period as industry capability develops.
That should not be read as a licence for loose controls. It is better understood as transition relief within a regime that still expects structured governance, reasonable processes, and disciplined evidence.
Assurance readiness starts with ownership, data lineage, documented assumptions, and preserved versions of disclosures and working papers.
Teams that wait until year-end to gather support usually find that the real problem is not disclosure wording, but fragmented evidence, unclear review authority, and weak audit trails.
