A significant decline in mortgage applications has been reported by Westpac Banking Corp, Australia's second-largest lender. The drop is attributed to recent tax changes in Australia.

The decline in mortgage applications is substantial, with a 20% fall noted. This change may have implications for the housing market, particularly for investor housing.

Further details on this development can be found in the original report from the Galveston County Daily News, which cites a story from Reuters. The report provides more information on Westpac's forecast and the impact of the tax changes on mortgage applications.
