Tax Savings App for Australia - Need approved Accountant

I need a thorough testing of my tax savings app to ensure all features work correctly. It should be done only by a qualified Accountant from Australia only. Key areas to focus on: - Tax savings calculations and results - Saving, editing, and viewing tax information - Useability and ease of the app Requirements: - Can the app be a handy tool for Accountants to support their customers - Experience with QA testing - Attention to detail - Ability to provide comprehensive feedback Testing will be done on a test version with sample data which is stored in an individual laptop/system (data doesn't stores in server)
