Australian immigration law is incredibly complex and changes frequently. A migration agent understands these laws and has the skills to navigate this complex system.
Under Australian law, a migration agent operating in Australia must be registered with the Office of the Migration Agents Registration Authority (Office of the MARA). The Office of the MARA is the body in Australia that regulates the industry.
Registration gives you protection. A registered migration agent is required to bound by a strict code of conduct, a set of professional and ethical standards to which they must adhere.
