The full answer
The timeline depends on audit type and current auditor capacity. The standard pathway: 1) Application lodgement to NDIS Commission (1-2 weeks), 2) Audit body engagement and document preparation (2-4 weeks), 3) Stage 1 audit / Verification audit (3-6 weeks), 4) Stage 2 audit if required (4-8 weeks more), 5) Closing non-conformities (up to 90 days), 6) Registration granted (1-2 weeks after closure). With audit demand spiking ahead of the 2027 mandatory registration deadline, expect timelines to lengthen — apply 6+ months before you need to be operational.
