Information about student visas can be obtained from the Australian Government Department of Home Affairs at homeaffairs.gov.au
While on a student visa, it is your responsibility to uphold your visa conditions. For information about your student visa conditions, please contact the Department of Immigration and Citizenship (DIAC) or refer to the information provided by DIAC at the time of your visa grant.
Student visa requirements include:
Generally, family members who intend to accompany you to Australia may be included in your application for a student visa and can be processed for visa entry at the same time. They must undergo a medical examination and hold health insurance, among other things. If your family members decide to come to Australia after you have arrived, they will have to apply for a visa separately. They may also require you to nominate them for entry.
Where you have school age dependents who will accompany you to Australia, you must make adequate arrangements for their education whilst here and school fees may be incurred.
