The Australia Tourist Visa (subclass 600) provides visitors with a period of 3, 6 or 12 months to stay based on their travel objectives and visa application category. A typical tourist stay after entering Australia lasts for three months. You can request extended stays when you visit family members or have specific travel arrangements. It is mandatory to exit Australia before your visa expires unless you submit an extension request from within Australia. The violation of your visa terms will affect your future visa eligibility so you need to stay within the date range and comply with the specified regulations.
