Things to consider before lodging an application

Entering and leaving Australia

Travellers should familiarise themselves with Australia’s border and entry requirements. For further information, see ‘Entering and leaving Australia’ at: https://www.homeaffairs.gov.au/covid19/entering-and-leaving-australia


Visa applicants outside of Australia will need to provide biometrics when they apply for a visa that is part of the Australian biometrics program, or where they are from a country, or located in a country at time of application that is part of the Australian biometrics program.

For information regarding Australia’s biometric program including visas and countries that are part of the program, please see: https://immi.homeaffairs.gov.au/help-support/meeting-our-requirements/biometrics

Invitation and registration to attend the event

Although this is a separate process to lodging your visa application, when assessing whether you meet the criteria for the grant of a visa, the department may take into account whether you are registered or were invited to attend the event.

Confirmation of registration, or a copy of your letter of invitation, should accompany visa applications. For online subclass 400 and subclass 600 applications, information about documents that need to be attached will be provided as part of the application process.

To request a letter of invitation please contact the secretariat.

Visa Application Process and Processing Times:

Visa applications are assessed on a case-by-case basis, and actual processing times can vary due to individual circumstances including:

  • whether the applicant has lodged a complete application, including all necessary supporting documents and paid associated visa application charges
  • how promptly the applicant responds to any requests for additional information
  • how long it takes to perform required checks on the supporting information provided
  • how long it takes to receive information from external agencies, particularly in relation to health, character, and national security requirements
  • when the application is lodged taking the current global visa processing times into account More information about visa processing times please see: https://immi.homeaffairs.gov.au/visas/getting-a-visa/visa-processing-times/overview.

For this reason, we would advise that visa applications be lodged at least 4 to 6 weeks prior to a person’s intended date of travel.

Applying for a Visa | Migration health requirements

Visitors to Australia are all required to meet Australia’s stringent migration health requirements and, depending on which visa you apply for, you will be asked to complete some form of ‘health declaration’ when you apply. It is important to acknowledge any existing health conditions you may have when completing this form, but please bear in mind that Down Syndrome is a disability, not a health condition!

In your application form you may be asked to advise whether you or any of your party intend or expect to seek medical treatment while in Australia for a range of different medical and health conditions, including ‘other’. If you have no plans to visit a doctor for a medical condition related to your present circumstances, then the correct answer is NO. There is no requirement and no need to state that you or a family member has DS. Doing so may lead to unnecessary delays in the granting of your visa, including the need to undertake a migration health examination.

Similarly, if you are asked any question about mobility, this relates to the use of a wheelchair, not whether you or your family member would be confident catching a bus or crossing a street by themselves.

If you subsequently need to visit a doctor in Australia for any reason, then that is perfectly OK!

If you encounter any difficulties with health issues when completing your visa application form, please contact the WDSC Secretariat at info@wdsc2024.org.au and we may be able to help.
