Determining the "best" and "cheapest" university for a BSc in nursing in Australia can be subjective, as tuition fees vary for domestic and international students. Some Australian universities offering quality nursing programs include the University of Sydney, the University of Melbourne, and the University of Queensland. However, tuition costs can be relatively high for international students. It's recommended to research scholarship opportunities and consider universities in regional areas, where living costs might be lower. Comparing individual programs, scholarships, and living expenses will help you find the best fit for your budget and academic goals.
