Australian visa applications can be submitted by providing a valid passport, passport-sized photographs, proof of English language proficiency, educational certificates, employment records, financial statements demonstrating sufficient funds, health insurance proof, and a comprehensive travel itinerary.
Additionally, applicants need to provide police clearance certificates from all countries they have resided in for more than 12 months. It's essential to check the specific visa subclass requirements, as document prerequisites might vary. Consulting the official Australian immigration website or a qualified immigration consultant is advisable for accurate and updated document guidelines tailored to individual visa categories.
