The drive log module could be made compliant with NHVR's requirements for an electronic work diary and approval sought from NHVR. See https://www.nhvr.gov.au/safety-accreditation-compliance/fatigue-management/electronic-work-diary. This could possibly negate the requirement for the CFA's written log book, although it would need to be simple to fill out, just like the CFA log book is simpler than a standard written log book.
