The immigration department's online service has gone down.
The ImmiAccount website on Wednesday afternoon posted the message: "Unplanned System Outage. ImmiAccount is currently unavailable. Technical teams are investigating the issue."
The service that allows users to lodge a visa or citizenship application and check progress of applications continues to remain unavailable due to an "unplanned outage".

"This message will be removed when full ImmiAccount access is restored. Please try to login again later," a notification on the website reads.
The department said in a statement there were "IT issues" affecting the call centre, website and emails.
"All of our systems which are critical to the security of the Australian border continue to function as normal," the department said.
"These issues are in no way linked to those experienced by the Australian Bureau of Statistics."
Earlier, the Australian Bureau of Statistics has taken down its census site which couldn't be restored so far. The government has launched an investigation after a series of "denial of service" attacks which are believed to have come from overseas.
