Yes, you can migrate to Australia without a job offer through several visa categories. The Skilled Independent visa (subclass 189) allows skilled workers to apply based on points without employer sponsorship. State-nominated visas (subclass 190) and regional visas (subclass 491) may also be available if states or territories nominate you. However, meeting the points test and having an occupation on the skilled occupation list are essential. While having a job offer can strengthen your application, it is not mandatory for all skilled migration pathways.
