We, as the congress organisers, are unable to provide updates on the status of your visa application – this is strictly the role of the Australian Department of Home Affairs.

Additionally, we are also unable to impact or alter the outcomes of visa applications. You will need to contact the department of Home Affairs directly for an update on this information. 

Should your visa application be refused, we will refund your registration costs less an AUD$250.00 administrative fee. Proof of refusal will be required, and all refunds will be processed post-congress.
