Westpac sister brand · since 2008

St.George — one of four Westpac brands sharing one credit team and four rate cards.

The honest framing: St.George is structurally identical to Westpac on underwriting. Same policy manual, same credit team, same APRA regulation. What differs is the price the same file gets quoted at across the four brands — and on a real refinance that gap is worth $850 to $1,700 per year. The pickoff matrix below shows where St.George wins.

The four-brand matrix · structural pickoff

Same credit team. Four rate cards.

All four Westpac sister brands assess the same file with the same underwriting and policy. They publish independent rate cards because brand-management decisions and competitive positioning differ — even though the credit risk being priced is identical. That's the pickoff. Below: how the four brands compare on the four metrics that matter to a broker-channel borrower.
