The Great Southern Bank Open Banking Consumer and Public APIs provide access to customer and non-customer related information.

To access the Consumer APIs, you will need to:

  • be accredited by the Australian Competition and Consumer Commission (ACCC), and
  • be provided consent by the customer.

Our APIs currently cover information about:

  • features, rates and fees for savings and transaction accounts, credit cards, term deposits and home loans;
  • availability and planned outages; and
  • customer details.

We will update the APIs progressively in line with the Consumer Data Right legislation timeframe.

Great Southern Bank APIs are designed and documented to adhere to the Australian Consumer Data Standards.
