Most travelers need a valid passport to enter Australia, including Gold Coast. Visa requirements vary depending on nationality and purpose of visit. The most common visa for short-term tourism is the Electronic Travel Authorization (ETA), which can be applied for online. Other visas, such as the tourist visa (subclass 600) or the working holiday visa (subclass 417), may be required for longer stays or for professional purposes. It is always recommended to check the official website of the Australian government for the current visa requirements before traveling.
