Short answer — choose a MARA‑registered Australian migration agent or a reputable Australian immigration law firm. Below are well‑known, widely used providers plus how to verify and choose safely.

Top reputable options (examples you can consider)

• Fragomen (global immigration law firm with full Australian offices and registered practitioners). (Fragomen.com)
• Migration Expert (Australian MARA‑registered migration agent firm that advertises specialist Australia services). (migrationexpert.com.au)
• Fragomen and similar established immigration law firms or specialist MARA‑registered firms in Australia (many medium/small Australian MARA practices also have very good records — search locally by city). (Fragomen.com)

Why these types of providers

• MARA‑registered migration agents and Australian immigration lawyers are legally authorised to give immigration advice and represent you; using an unregistered consultant risks poor advice or fraud. (Official OMARA / MARA register is the authoritative list). (portal.MARA.gov.au)

Red flags and known complaints

• Large Indian/overseas consultancies (widely advertised names) can have highly mixed reviews — many people report good outcomes but there are also repeated negative reviews and scam‑type complaints online. Check independent reviews before you engage. (Examples of mixed/negative reviews are visible publicly). (Trustpilot.com)

How to choose and verify an agent — checklist (do these before you pay)

1. Ask for their MARN (Migration Agent Registration Number) or lawyer practising number and verify it on the MARA register (official site). If they’re not on the register, do not pay for immigration assistance. (portal.MARA.gov.au)
2. Check whether they are a lawyer with an unrestricted practising certificate (lawyers can give immigration advice even if not on MARA). Verify via the relevant Australian state law society if in doubt. (MARA.gov.au)
3. Look up independent reviews (Trustpilot/Google/Reddit) but treat them critically — focus on patterns (refunds, communication, false guarantees). (au.Trustpilot.com)
4. Get a written service agreement: clear fees, milestones, refund policy and scope of work. Avoid anyone promising a “guaranteed visa.” (blueorbs.com.au)
5. Prefer firms that provide an initial written assessment and will put the responsible MARA agent’s name and MARN on the contract. (portal.MARA.gov.au)

If you want, I can

• Look up MARA‑registered agents in your city (India) who advertise Australia services and list their MARNs and reviews.
• Compare 3–5 specific firms (fees, services, typical visa streams they handle) and link to their MARA entries.

Which of the follow‑ups would you like: a short vetted list for applicants from India (with MARNs), or a comparison of 3–5 specific firms (fees/services)?
