Borrowing power is not a vibe and it is not the number on a homepage calculator. Lenders haircut your income, load your expenses, apply a regulator's buffer, and then decide whether the residual looks like a loan they can defend. This hub is the methodology.
Start with how lenders calculate borrowing power, then the serviceability buffer and HECS-HELP.
A broker is a search and a file-builder paid by lenders; a bank is a single credit box. Neither is free of incentives. Choose based on the complexity of your file and your willingness to shop.

Australian lenders must assess home loans as if the rate were higher than the contractual rate, by a buffer APRA sets. That buffer is why you cannot borrow the repayment you can 'make today'.

Borrowing power is a credit-policy output: assessable income, haircut, expenses, existing commitments, HEM versus your statements, and a serviceability buffer on the proposed rate. The homepage calculator is theatre.
