Kind of cool, but I bank with the bank in question (Ubank / National Australia Bank) and I'm not sure I'm completely comfortable that they'd use my transaction history like this.
I wonder how accurate this actually is... I punched in my details and apparently for my details there are less then 10 people like me. Considering where I live, age etc... that seems unlikely.

If your identity isn't attached... it isn't your history. It's just 'a' history.

what if there are only 5 'people like me'. Or even 1 or 2.

All identifying information had been removed/sanitised, they could tell from looking at the spending habits.
I disagree with your statement.
I'd say the initial 6 questions are modelled on Census data, not anonymous bank records.
- Name
- Phone
- Address
- Tax File Number (not unlike a US social security number)
I came to the same conclusion that its probably based on census data.
