Australia's Temporary Graduate Visa (subclass 485) typically requires completion of a 2-year program. However, there's a streamlined 485 (Graduate Work stream) option for those who have completed a trade qualification or degree in Australia that lasts for at least 16 months but less than 24 months. This offers an 18-month stayback period. For programs less than a year, you might not be eligible for the 485 visa. Always check the latest immigration regulations for the most accurate and up-to-date information.
