First: check the dates
An improvement notice sets out what needs to be fixed and the date by which it must be done. Two deadlines matter straight away:
- Internal review: if you disagree with the notice, WorkSafe WA says a request for review must be made before the earlier of 14 days after the notice was issued or the end of the compliance period — and it recommends lodging at least three working days before the compliance period ends. The notice remains in force while it is reviewed.
- Extension of time: under section 194 of the Work Health and Safety Act 2020 (WA), the regulator can consider extending the compliance period — but only if the application is made before the compliance date has passed.
If you are still dissatisfied after internal review, external review may be available through the Work Health and Safety Tribunal at the WA Industrial Relations Commission.
Practical steps
- Read the notice carefully and list each issue and the underlying requirement.
- Work out what evidence will show the issue is fixed — procedures, inspection records, training and competency records, equipment registers.
- Fix the underlying weakness, not just the symptom the inspector saw.
- Keep a simple evidence matrix that links each item in the notice to its evidence.
- Notify WorkSafe WA once you have complied (for mining, through the Safety Regulation System).
Notifying compliance
WorkSafe WA asks that you notify the regulator as soon as reasonably practicable once the notice has been complied with. General industry notifications use the notice number, issue date and inspector's name; mining notifications are made through the Safety Regulation System (SRS).
