How frequently do Microsoft adjust pricing in Australian dollar?

Microsoft will maintain relatively stable and predictable prices in Australian dollars and other currencies. Periodically Microsoft assesses the impact of its pricing to ensure there is a reasonable alignment with the needs of its customers, partners, and the marketplace across the region, and may make changes in response to its assessment and feedback. Any future changes to pricing will be assessed based on Microsoft’s internal pricing strategy and processes to maintain relatively stable prices while ensuring close alignment of prices to US dollar levels.
