 Changes are being made to Australia's visitor visas that will make it easier for you to choose the right visa for your needs. The new temporary work short stay activity, subclass 400 visa, is for people who want to travel to Australia to undertake short term, non ongoing, highly specialised work or to conduct an activity as an invited participant. If you are a highly specialised worker, you will need to meet all of the following. Have specialist skills and knowledge that are not accessible in Australia. This means your work can't reasonably be undertaken by an Australian citizen or permanent resident and your work will be required for a short period to undertake a task or series of tasks on a non ongoing basis. Examples of this type of work might include installers of imported equipment, after sale service or emergency repair work. To be eligible for this visa, you will need to be invited by an organisation operating lawfully in Australia to participate in a specific event or events or to participate in social or cultural activities. For example, sports people participating in specific sporting events or touring as part of a sports team. More information about the changes is available on the department's website.
