Visas in Australia are classified as follows –
Immediate Tourist Visa
These visas are issued by the Australian Department of Immigration and Border Protection for intervals of 3, 6 and 12 months. The tenure of the visa depends upon the nature of the trip. The Immediate Tourist Visas are usually provided to people who bear the sole purpose of business or come as tourists.
These visas are given to travelers using Australia as a way of transit, state, in the event of a layover or if a customer plans to join a merchant navy or ship team in the nation. Transit visas are usually permitted for a length of just about 72 hours.
Working Holiday Visas
These visas are meant for people within the age of 18 and 30 years wishing to travel in addition to work in Australia for a year. Working Holiday visas are especially oriented towards catering drop-year travelers who would like to explore and at precisely the exact same time, work their way to supplement their costs.
Business Visas are offered to people with established companies in Australia or people that are sponsored by a governmental or multinational company with the objective of conducting business operations in Australia under the purview of the employer.
