Electronic Travel Authority for exempting any Visa is mandatory for the people who travel to Australia. The ETA can be applied anytime an individual desires to travel to foreign countries. However, the best time to apply for the Australia eta is immediate while the plan for the travel is being made as it requires a bit of time to come over. There are a lot of verifications done before the ETA is granted and the final entry to the foreign countries including Australia is granted by the custom security officials after thorough checking. They have the right to either grant permission for the entry of the individuals within the country or if they find any complications or detect the individual as a threat they can immediately discard the ETA and prohibit the person from entering the country.
The ETA is connected through electronic mode to the passport of the individual. This needs to be applied online and it needs to be made sure that it is in connection with the ETAS, which is an approval before the entry within the country granted by the customs officials. There are certain specific rules for the individuals visiting other countries and the purposes of the visit should be either a visit to their families and friends, business meetings, events, exhibitions, etc. The condition of the ETA grant is that the individual can stay for a maximum time span of 90 days. The person visiting Australia must possess no other Visa for the same country.
The application for an ETA is very simple as an individual simply needs a passport, a credit card, and an email address. There are a lot of associated protocols and norms that are not disclosed and the primary among them is the screening test that every individual goes through while applying for the ETA.
