Australian citizens currently receive visa exemption for tourism on arrival at Thai international airports, including Phuket. Length of stay and conditions are set by Thai immigration and can change, so check Smartraveller and the Royal Thai Embassy before booking.
Your passport should have at least six months validity beyond your planned departure. Immigration may ask for proof of onward travel and accommodation. Keep your departure card stub if issued.
Longer stays, working or studying require the correct visa in advance. Overstaying attracts fines and can affect future entry.
