In late October 2026, research from the comparison site OurTop10 found that 18% of Australians admit to using AI to create or alter documents they gave a lender. Among Gen Z the figure was 56% (Yahoo Finance Australia). OurTop10's head of research, Mansour Soltani, was blunt about it: "It's financial fraud."
Australian lenders are not the only ones receiving doctored paperwork. Universities and the Department of Home Affairs have spent the past year tightening checks on the same kinds of documents (bank statements, transcripts and English test results) submitted with student visa applications. The common thread is that editing a PDF or generating a convincing statement now takes minutes, while most review processes still rely on someone looking at it.
Key takeaways
- AI document editing is mainstream. 18% of Australians, and 56% of Gen Z, say they have used AI to create or alter documents for a lender, according to OurTop10.
- Bank statements top the list. Bank statements (10%) were the most common, followed by employment documents (9%) and payslips or proof of income (6%).
- Visa checks have tightened. Since 8 January 2026, student visa applicants from India, Nepal, Bangladesh and Bhutan sit at Evidence Level 3, which means more financial and academic evidence.
- The checks have to move from eyes to evidence. A doctored statement is built to pass a glance. Arithmetic, metadata and pixel-level checks don't depend on how convincing it looks.
What the October survey found
OurTop10's research, reported on 20 October by Wisevoter (citing Real Estate Australia) and on 23 October by Yahoo Finance Australia, breaks down which documents people say they changed:
Employment documents (9%), payslips or proof of income (6%) and competing lenders' offers (3%) made up the rest. The publications don't give a sample size or method, so treat the exact percentages as indicative. The direction matches other evidence, though: Yahoo Finance notes the Australian Financial Review's report that the Commonwealth Bank told authorities in March 2026 that about $1 billion had been lent on illegitimate home loans, some involving AI-doctored documents.
Soltani's other comment explains why lenders should be concerned: "They think they can get away with it." Most of the time, they probably do. A bank statement changed in a chat-based AI tool or a PDF editor looks right, because it was built to look right.
The same documents, in student visa applications
Universities face a version of the same problem. In January 2026, the Department of Home Affairs moved student visa applicants from India, Nepal, Bangladesh and Bhutan from Evidence Level 2 to Evidence Level 3, effective 8 January. A Home Affairs spokesperson said the change would help manage "emerging integrity issues" (Information Age). Together, the four countries account for about 30% of Australia's international students.
At Level 3, applicants can be asked for more evidence of funds, including bank statements that are manually checked, plus authenticated academic transcripts and more English-language evidence (Immigration Monitor). The background includes large seizures of forged degree certificates: Information Age cites a Kerala police case involving about 100,000 fake degrees with forged signatures, holograms and university seals.
This follows the Student Visa Integrity Alert Home Affairs issued in November 2025, which warned universities about falsified passports, bank statements and English test results in applications. Some universities responded by restricting recruitment from particular regions, an approach Home Affairs has said it doesn't support.
For education providers: a weak integrity record can affect an institution's risk rating and visa processing times for all its applicants. Checking documents at offer stage protects genuine students as well as the provider, because it avoids blanket regional restrictions.
Why "looks fine" is no longer a check
A human reviewer tends to compare a document with what they expect a real one to look like. AI tools are very good at producing exactly that. What they're much worse at is consistency that can be tested:
- Arithmetic. A bank statement's running balance has to reconcile from row to row and from page to page. Inflating one deposit without updating every later balance breaks the chain. See our guide to tampered bank statement detection.
- File history. A statement claiming to come from an Australian bank's statement system but produced by a consumer editor, or saved again after the bank generated it, leaves traces in the PDF structure and metadata.
- Pixel and font evidence. Edited figures often differ slightly in rendering, compression or font metrics from the text around them, even when they look identical on screen.
- Cross-document consistency. The salary on a payslip, the deposits on a bank statement and the employer in an employment letter should agree. Fraud that survives one document often fails across three.
- AI generation traces. Fully generated documents and screenshots carry artefacts that don't appear in genuine bank output.
Where TamperCheck fits for Australian lenders, brokers and universities
TamperCheck runs these checks on each upload and returns a verdict with the evidence behind it, typically in about a minute. Lenders and brokers use it for bank statement fraud detection and payslip verification before an application reaches credit. Admissions and compliance teams use it on transcripts, degree certificates, English test results and financial evidence, alongside the Genuine Student assessment.
It doesn't replace responsible lending checks or the Genuine Student assessment. It means the documents those decisions rest on have been checked for more than whether they look right.

- How many Australians use AI to alter loan documents?
Research by OurTop10, reported in October 2026, found that 18% of Australians admit to using AI to create or alter documents for a lender, including 56% of Gen Z and 36% of Millennials. Bank statements were the most commonly altered document. No sample size was published, so treat the figures as indicative.
- Is using AI to change a bank statement for a home loan illegal in Australia?
Giving a lender a document you know is false to obtain a loan can amount to fraud under Australian law, and lenders can decline or cancel the loan. Using AI to make the change doesn't alter that.
- What is Evidence Level 3 for Australian student visas?
It is the highest evidence level under the Simplified Student Visa Framework. Applicants may need to provide more evidence of funds, such as bank statements that are manually verified, plus authenticated academic transcripts and more English-language evidence. India, Nepal, Bangladesh and Bhutan moved to Level 3 on 8 January 2026.
- How can lenders detect an AI-altered bank statement?
Check that running balances reconcile on every row and page, inspect the PDF's structure and metadata for re-saves or editing tools, look for font and compression differences around figures, and compare income across payslips and statements. TamperCheck automates all of these.
- How can universities verify international student documents?
Run forensic checks on transcripts, degree certificates, English test results and bank statements at offer stage, and compare names, dates and figures across the whole application. That catches edited or generated documents before they reach a visa application.
