Typically a stage 1 audit is undertaken by an auditor without you being present. They go through a document review to check all the policies, documentation and requirements are met to enable the Stage 2 process to be undertaken. By moving to the Stage 2 which may be remote or in person, it is where you demonstrate application and processes consistent with the documents provided in stage 1 and against the standards and registration groups that you have nominated. If the auditor feels at stage 1 there are significant gaps, they may recommend delaying stage 2 or resubmission of the stage 1 self assessment and documents as significant work is involved based on the information they have received.
