Supporting evidence should make the facts in your application easier to verify. The exact documents depend on your circumstances, but consistency across employment dates, duties, projects, and identity records is essential.
Build a simple evidence register before drafting. Note each employer or engagement, the dates, the available reference, payment or business evidence, and the projects that relate to that period.
Check that scans are legible, complete, and named clearly. If a document has several pages, keep the order intact and make sure any translation or certification requirement has been considered.
Use current ACS instructions as the authority for document requirements. A review can help identify gaps, but it cannot replace official evidence or an employer-issued reference.
