A form of permission for a non-citizen to travel to, enter, transit or remain in a particular country. A visa does not guarantee entry. That remains the right of the immigration officials of the country concerned. Some countries may ask visitors to present return tickets and evidence of means to cover intended stay. Some countries refuse entry to visitors who do not comply with their requirements regarding general appearance and clothing.
Some countries have compulsory currency exchange regulations on first entry.
You should check with the Consulate direct. In the case of those countries which do not have a presentation in Australia you should contact the closest Consulate 6. Deportation is at the traveller's expense. Be aware that if you have the visas of some countries in your passport you may be refused entry into others. Check with the appropriate Consulate.
