Exhibit 1

ASX Release 3 April 2024 S&P Global Ratings (S&P) upgrades ratings for Westpac Banking Corporation (Westpac) and Westpac New Zealand Limited (WNZL) Today S&P upgraded the stand-alone credit profile of Westpac by one notch to ‘a+’ from ‘a’ to reflect its assessment that industry-wide risks for Australian banks have reduced. There is no change to the issuer credit rating of either Westpac or WNZL, and the ratings outlook for both entities remains stable. Westpac’s Additional Tier 1 and Tier 2 rated capital instruments received a one notch upgrade. WNZL’s rated Tier 2 capital instruments have also been upgraded by one notch, reflecting the improved stand-alone creditworthiness of Westpac.
