An audit is not a test you cram for. A certification auditor is checking whether your system is real and in use, which is something you either have or you do not. Preparation is about making that evidence easy to find.
Keuer Solutions is an independent HSEQ consultancy. ISO certification is issued by JAS-ANZ accredited certification bodies, not by Keuer Solutions. We also run SWMS Aus, an online store selling SWMS and HSEQ template packs for Australian trades.
