TLDR
Suncorp Bank home loan borrowers who have paid ahead of schedule face higher minimum repayments when their accounts move to ANZ platforms by June 2027. ANZ does not reduce minimum repayments after advance payments, unlike Suncorp. Canstar's Sally Tindall warned thousands of customers face an unwelcome shock at changeover.
Who is affected and what the dollar hit looks like
Suncorp Bank home loan customers who have paid ahead of schedule face higher minimum monthly repayments when their loans transfer to ANZ platforms. Suncorp's own Move Hub notice illustrates that a $40,000 advance on a $400,000 home loan would push the monthly minimum from $2,544 at Suncorp to $2,827 at ANZ.[1]
Sally Tindall, Data Insights Director at Canstar, said thousands of Suncorp customers were likely to face an unwelcome shock when they learned their minimum repayments were set to rise due to the changeover.[4] Suncorp Bank CEO Malcolm Stedman said "for most customers there will be no change to their repayments."[4]
Why ANZ's method produces a higher minimum
The gap between the two banks comes down to how each calculates the minimum monthly repayment after a borrower makes extra payments on their home loan ahead of schedule. At Suncorp, advance payments reduce the loan balance and trigger a recalculation of the minimum repayment downward.[1]
Under ANZ's method, advance payments still reduce the outstanding balance but do not trigger any recalculation of the minimum repayment; instead, ANZ bases the required payment on the sum of the outstanding balance plus any redraw or Cashback funds held.[1] Borrowers who built up a buffer by paying ahead at Suncorp will find that buffer no longer reduces their monthly obligation once the account sits on ANZ's platform.
What borrowers can do before June 2027
Suncorp's Move Hub notice sets out one practical option: borrowers can apply some or all of their available Cashback or redraw balance to permanently reduce their loan principal before the transfer takes place.[1] Reducing the principal that way would lower the base ANZ uses to calculate the minimum, softening or eliminating the repayment increase.
All 1.2 million Suncorp Bank customers are scheduled to move to ANZ products, services and digital platforms by June 2027, following ANZ Group's acquisition of Suncorp Bank, which completed in July 2024.[2]
Suncorp's email to customers on 13 October said: "If you've made advance payments and have funds available in your Cashback/redraw, your minimum loan repayment at ANZ is likely to increase."[4]
