A visa is a government sanctioned permit to enter, stay and exit a country granted to foreign nationals who wish to visit the concerned country. It is considered to be the entry ticket to a country which is mandatory irrespective of the nature of the visit. Just like almost all first world countries, an Australian visa is indispensable for a foreigner who wishes to visit the country. Surely, the Government of Australia has segregated the applications for the country visas depending upon the nature and tenure of the visit.
Visas in Australia are legally classified as follows –
Instant Tourist Visa
These visas are issued by the Australian Department of Immigration and Border Protection for periods of 3, 6 and 12 months. The tenure of the visa depends on the nature of the visit. The Instant Tourist Visas are generally provided to visitors who bear the sole purpose of business or come as tourists.
It is necessary for visitors to hold a valid passport and are often supplied with an Australian ETA, which stands for Electronic Travel Authority. The ETA visa electronically links with the visitor's passport for a fixed duration of time. Immigration authorities are thus, provided with prior knowledge about a visitor's visa status.
These visas are provided to travelers that use Australia as a means of transit, say, in case of a layover or if a visitor intends to join a merchant nav or ship crew in the country. Transit visas are generally permitted for a duration of only about 72 hours.
Working Holiday Visas
These visas are meant for people within the age of 18 and 30 years who wish to travel as well as work in Australia for a year. Working Holiday visas are particularly oriented towards catering drop-year travelers who wish to explore and at the same time, work their way to supplement their expenses.
Business Visas are provided to people with established businesses in Australia or people who are sponsored by a governmental or multi-national company with the purpose of conducting business operations in Australia under the purview of their employer.
The Department of Immigration and Border Protection are particularly cautious while issuing Student visas. The government permits a visa to a traveling student only after the submission and acceptance of a thorough, detailed analysis of the concerned student's course of study and financial backing. This visa is classified according to the nature of the study. Separate visas are issued for international students who intend to travel to Australia for their graduate or postgraduate degree as opposed to a student traveling for a high school exchange program.
Students holding this visa are not permitted to work before the commencement of their study and can only apply for a job with a cap of up to 20 hours a week.
These visas are a permanent migration permit which allows foreign nationals to migrate to Australia under the pretense of being skilled in a domain of significance according to the Government of Australia.
