A mortgage broker compares home loans across many lenders and handles the paperwork for you, while a bank only ever sells you its own products. For most people with a slightly messy situation or no spare time, a broker is the easier path. If you already know exactly which loan you want, going direct can work just fine.
That is the short version. The longer version is worth a few minutes, because this is one of the bigger financial decisions you will make, and the right answer depends on you rather than on which option sounds cleverer at a barbecue.
What a mortgage broker actually does
A mortgage broker sits between you and a panel of lenders. Instead of filling in one application with one bank and hoping, the broker looks across their panel, narrows it to loans that fit your situation, and manages the application from first chat to settlement. They chase the lender, translate the jargon, and tell you when a valuation has come back light.
Two things matter most here. First, brokers are generally paid a commission by the lender, not by you, so their service usually costs you nothing directly. Second, since 2021 they have been bound by a best interests duty, which legally requires them to act in your interests when recommending a loan. A bank salesperson has no such duty to you.
That does not make brokers saints. Their panel may not include every lender, and commission structures can still nudge behaviour at the edges. A good broker will happily tell you which lenders are on their panel and roughly how they are paid. If yours dodges that question, that is your answer.
What going direct to the bank gets you
Going straight to a bank means you deal with one lender offering one menu. The upside is real: banks sometimes reserve sharper deals for existing customers, especially if you already have your salary, savings and offset sitting with them. If you have a long, tidy relationship with your bank, it is worth asking what they will do to keep you.
The catch is that a single bank cannot tell you whether the lender down the road would have said yes faster, or shaved a chunk off your rate. You are comparing one option against itself. That is fine if you have already done the legwork and know the market, and genuinely frustrating if you have not.
When a broker helps most
Brokers earn their keep when your situation is anything other than vanilla. The further you sit from a salaried borrower with a 20 per cent deposit and a clean file, the more a broker is likely to save you in time, stress and knockbacks.
Consider a broker if any of these apply:
- You are self-employed or have variable income, where different lenders assess the same numbers very differently.
- You have a low deposit and need a lender comfortable with lenders mortgage insurance or a guarantor.
- You are juggling several options and want someone to compare them properly rather than guessing.
- You simply do not have the hours to ring six lenders and decode their fine print.
- You have been knocked back once and do not want a second credit enquiry counting against you.

When going direct can work
Direct works best when you know what you want. If you have already compared the market, understand the difference between a rate and a comparison rate, and your finances are straightforward, dealing with one lender can be quick and painless. There is no third party to coordinate, and a loyal-customer discount can occasionally beat a broker deal.
The trick is to do enough homework that you are not flying blind. Skimming current offers, such as the running list in our best home loan rates Australia coverage, helps you walk in knowing what good looks like. Even when you plan to go direct, it pays to compare lenders before you commit so the bank’s offer has something to be measured against.
Brokers save you legwork. Banks occasionally save you money. Either way, the comparison rate is the number that tells the truth.

The numbers that matter, whichever path you pick
Whether you use a broker or go direct, two things decide whether you got a good deal. The first is the comparison rate, which folds most fees into a single figure so you can compare loans more fairly than the headline rate alone allows. The second is the full list of fees: application, ongoing, offset, redraw and discharge costs that quietly add up.
Ask for everything in writing. If you are refinancing, factor in exit and setup costs so a slightly lower rate does not get eaten alive. For the wider picture on structuring and features, our home loans Australia guide walks through the parts a single rate never captures.
Rates, thresholds and lender rules change often, so confirm anything that affects your decision directly with the source: your fund, your lender, ASIC’s Moneysmart, or the broker’s own disclosure.

The bottom line
A mortgage broker is usually the easier choice if your situation is even slightly complicated or you are short on time, and it typically costs you nothing because the lender pays the commission. Going direct can be the smarter move when you already know the market and want to lean on a loyal-customer deal. Whichever you choose, compare the comparison rate, get every fee in writing, and remember that the cheapest headline is not always the cheapest loan.
