System responsiveness and outages - 27 June to 1 July 2013
Clients might be having difficulty in lodging applications and attachments. We are investigating the cause of the problem; however, we are not able to provide timeframes for resolution. The department's eLodgement systems will be offline for system upgrades from 28 June 2013 and may not be available again until 1 July 2013. Clients planning to apply online for any Australian visa, prior to the introduction of new visa pricing and policies on 1 July, are encouraged to lodge and pay for their application before 9 pm (AEST) on 28 June. Clients will not be able to lodge online visa applications while the systems are offline. If a client does not lodge their visa application prior to 1 July 2013, they will be subject to the new visa pricing arrangements.
