We recommend that applicants apply for their visa at least 6-8 weeks before their intended travel date to Australia.
Under Australia's universal visa system, all visitors to Australia must have a valid visa to travel to and enter Australia (other than New Zealand passport holders who will normally be granted a Special Category visa on arrival, provided they meet health and character requirements; and permanent residents of Norfolk Island who may be granted a Permanent Resident of Norfolk Island visa on arrival). For more information, see the fact sheet: http://www.immi.gov.au/media/fact-sheets/17nz.htm
There are many visa options available to people wishing to visit Australia. The appropriate visa option will depend, amongst other things, on the person's purpose for visiting Australia.
Visas for specific purposes
Please see the "Business Visitor Visa Information as at July 10" guidlines located in the "Downloadable Files" on the visa options to Australia. Applicants should read the section on "Business Visa - For example, speaking/presenting at a conference".
