Corella Audit Practice is Declan Farrugia, an independent lead auditor based in Melbourne who contracts to certification bodies for ISO/IEC 42001 and ISO/IEC 27001 audits and takes direct engagements for pre-certification readiness reviews. He has audited management systems since 2016 and added ISO 42001 to his scope when the standard was published. On the certification side, he is engaged by accredited bodies as a subcontracted auditor, so clients seeking certification should approach a certification body rather than Corella directly. For readiness work, he charges a published day rate and quotes small engagements at under $5,000: typically two days reviewing documentation and evidence, one day of interviews, and a written report listing likely nonconformities before the client's stage one audit. He works remotely only, which keeps costs down for clients outside Australia, and has completed readiness reviews for companies in the UK, Singapore and the United States. Declan does not write policies or implement controls, since doing so would compromise his independence for any later audit of the same organisation. Availability is usually four to six weeks out.
