Tasmania Police were notified at 5.30am this morning that the Hobart Airport website had been hacked and defaced.

A message placed on the site contained a statement supporting ISIS.

The group claiming responsibility for the hacking appear to non-discriminately target organisations who use web hosts such as the one used by Hobart International Airport.

Investigations have shown that identical messages have appeared on thousands of websites worldwide since late 2014.

There were no threats made towards the Hobart airport or flight operations to and from the airport.

Tasmania Police have been monitoring activity at the airport premises, and there has been no suggestion of targeted activities on-site.

We are committed to supporting the security arrangements at the airport and are prepared to provide an appropriate response.

A police investigation is underway and the Hobart Airport website has been taken offline by airport management, while investigations continue.
