What does the Electronic Travel Authority (ETA) provide?

The Electronic Travel Authority (ETA) specifically provides authorization for travelers to enter and travel to Australia. It is a digital visa that allows eligible foreign nationals to visit Australia for tourism or business purposes for short stays, typically up to three months. This system streamlines the application process, allowing travelers to apply online before their trip, making the entry process more efficient.

The other options relate to different travel authorities and immigration regulations in various regions. For instance, authorization to enter the Schengen Area pertains to European travel regulations and requires a Schengen Visa or similar authorization, which is not associated with the ETA. Additionally, the authorization for long-term stays in the U.S. involves a different set of visas or permits, which also do not apply to the ETA. Therefore, the specific function of the ETA is accurately represented by the choice related to travel to Australia.
