St.George Bank is owned by Westpac Banking Corporation and operates as one of Westpac’s banking brands rather than as an independent bank.

Quick Scoop: Who owns St George Bank?

  • St.George Bank is part of the Westpac Group, one of Australia’s big four banks.
  • It merged with Westpac on 1 December 2008 in an all‑share deal approved by shareholders and the Federal Court.
  • After the merger, St.George stopped being a standalone authorised deposit‑taking institution; its assets and liabilities moved onto Westpac’s balance sheet in 2010.
  • Today, St.George is a brand within Westpac alongside Bank of Melbourne, BankSA and others, but customers still see and use the St.George name, branches and products.

In simple terms: if you bank with St.George, you’re ultimately banking with Westpac behind the scenes.

A tiny bit of backstory

  • St.George began as a building society and later became an independent Australian bank headquartered in Sydney.
  • In 2008, Westpac acquired it in a large merger valued at about A$18.6 billion, folding St.George into the wider Westpac Group while keeping the brand alive for customers.

Why this matters for you

  • Your deposits and loans with St.George sit under Westpac’s regulatory and capital umbrella.
  • Brand experience (logo, app, branches) is St.George, but ownership, governance and prudential supervision link back to Westpac Group.

TL;DR: Who owns St George Bank? Westpac Banking Corporation does, and St.George now operates as a Westpac brand rather than a separate bank.
