Name: Western Australian WHS Act 2020 — Complete Reference
Author: teddychenfeiyang-png

Purpose

This skill provides the complete verified text of the Work Health and Safety Act 2020 (WA), extracted directly from the official Western Australian legislation. It ensures Claude cites accurate section numbers, provisions, and requirements when producing occupational hygiene reports, compliance analyses, duty analyses, and WHS documentation.

Critical Rules

Only cite provisions that appear in the part files. Never fabricate or assume section numbers or content.
Citation format: Use "s [number]" for individual sections, e.g. "s 19 of the Work Health and Safety Act 2020 (WA)" or "ss 35–39" for a range.
Use conservative, factual language when describing legislative obligations. Avoid subjective terms — describe what the Act requires in objective terms.
Always use Australian English spelling (e.g. behaviour, organisation, colour, defence, licence [noun]).
If a provision cannot be located in these files, state that the specific section should be verified against the current legislation and indicate which Part it is likely found in.
