MARA (Migration Agents Registration Authority) registration is the professional licence required to provide Australian immigration advice for a fee. Only MARA-registered agents can legally advise on Australian visa options and prepare visa applications for payment. Why it matters: (1) Legal protection — MARA agents are bound by a professional code of conduct; (2) Complaints mechanism — you can lodge complaints with the Office of the Migration Agents Registration Authority (OMARA) if something goes wrong; (3) Current knowledge — MARA agents must complete ongoing professional development. Verify registration at mara.gov.au using the agent's name or registration number. Using an unregistered agent for Australian immigration advice is illegal and puts your application at risk.
