Choosing the Right Agent for a Melbourne-Based Complex Case
Verify registration on the OMARA portal before anything else, ask directly about experience with your specific issue (cancellation, refusal, or tribunal work differ significantly), and get a written scope of work with fees separate from government charges. Avoid anyone who guarantees an outcome — no registered agent legally can.
Recent Regulatory Changes to Know in 2026
The Home Affairs-led OMARA crackdown on unregistered "front agents" has intensified through 2025-26, alongside character-test broadening under recent legislative reform. These changes raise the stakes for complex cases and make working with a properly verified, currently registered agent more important than ever.

Frequently Asked Questions
Do I need a lawyer or a migration agent for a complex case?
Either can represent you; a MARA-registered agent specialising in complex matters is often sufficient, though FCFCOA judicial review requires a lawyer.
Can I check if my agent is really registered?
Yes — search their MARN at immi.homeaffairs.gov.au/search/mara.
What happens if I miss an ART deadline?
In most cases the review right lapses permanently, making early advice critical.
