These mistakes turn up across every visa type, from student applications through to skilled migration. None of them are exotic, which is exactly why they cost so many people so much.
1. Missing a Deadline That Cannot be Moved
Some windows are absolute. The Temporary Graduate visa has to be lodged within six months of finishing your course, and that clock starts when your results are released, not on graduation day. Miss it and the pathway generally closes. No refund, no discretion.
Put every hard deadline in your calendar the moment it becomes relevant, and plan backwards from it.
2. Letting a Document Expire While You Prepare
English results, police checks and medicals all have validity periods, and some have been tightened. For the 485, your English result has to come from an in-person sitting taken within twelve months of lodging.
Sequence your tests so they’re still valid when you lodge, not just when you sat them.
3. Counting Money You Cannot Actually Reach
A number on a statement isn’t the same as available funds. Locked deposits with no early withdrawal, money parked briefly by someone else, or a sponsor whose income doesn’t explain the balance all invite doubt. Show funds that are genuine, traceable and reachable.
4. Submitting a Statement Someone Else Wrote
Template Genuine Student responses are a documented cause of refusal, and OMARA has sanctioned agents for precisely this. Case officers read thousands of these and spot recycled phrasing immediately. Write about your own circumstances, in your own words, even if the writing is plainer than you’d like.
5. Assuming an Occupation List Will Hold Still
Lists get reviewed and revised, and different lists govern different visas. The Core Skills Occupation List covers employer-sponsored pathways, while the points-tested visas run on separate lists entirely. Check your occupation against the list for the visa you’re actually applying for, at the time you apply.
6. Leaving Out Something You Think is Minor
Old refusals, a cancellation, an overstay in another country years ago, a criminal matter you assumed was spent, a health condition. Non-disclosure is treated as a credibility problem, and it’s punished far more severely than the thing itself usually would be. Disclose it and explain it.
7. Taking Sdvice from Someone Not Allowed to Give It
Only registered migration agents and Australian legal practitioners can lawfully be paid for immigration assistance. Advice from unregistered consultants, confident relatives or Facebook groups comes with no accountability and very often reflects rules that changed two years ago.
Check any agent’s MARN on the OMARA register before you pay, and treat a guaranteed outcome as a red flag rather than a selling point.
The Thread Running Through all Seven
Every one of these is a preparation failure rather than an eligibility failure. The people involved were usually qualified. They just treated the application as paperwork to be filled in, rather than a case that had to be evidenced.
Build your file early, check current requirements directly with the Department of Home Affairs, and have anything complicated reviewed before you lodge.
