A message on the website says there is an unplanned system outage which is being investigated.

The service allows users to lodge a visa or citizenship application and check the progress of applications.

The department has released a statement saying the issues are not linked to those experienced by the Australian Bureau of Statistics.

The A-B-S has temporarily taken down its census site and launched an investigation after a series of "denial of service" attacks, believed to have come from overseas.
