Migration agents who operate outside Australia do not have to be registered. The department may give some overseas agents an identification (ID) number. This number does not mean they are registered.
Registered agents operating outside Australia
Some migration agents registered with the Office of the Migration Agents Registration Authority (Office of the MARA) operate outside Australia. You can search for a registered agent outside Australia on the Office of the MARA website. Go to 'Find an Agent' and Search By Location Details: 'Country'.
