The Visitor visa (subclass 600) covers short-term travel to Australia for tourism, business activity, or visiting family, through separate streams built for each purpose. Stay length and conditions depend on which stream applies, and applying under the wrong one is one of the most common reasons applications stall.
We start with the purpose of your trip, not the paperwork. Tourism, business, and family visits sit under different streams with different evidence expectations, and applying under the right one from the start is faster than correcting course after a refusal.
