The fifth light tower at the Launceston venue was yesterday officially unveiled by Sports Minister Michelle O'Byrne and Launceston Mayor Albert van Zetten.

The tower was funded by the government's jobs package, and completed by Launceston-based construction company Darcon.

Alderman van Zetten said the ground needed the light to broadcast both cricket and AFL, and that the council was in contact with Cricket Tasmania about the potential of hosting a Big Bash League match or a domestic one- day match, depending on how those competitions were structured.

Ms O'Byrne said she was hopeful of more night AFL matches at the ground so the state could cash in on the tourism value that AFL brings.

There will be a preseason match on February 21 and a twilight match on March 22.

The lights will also benefit State League clubs North Launceston and Western Storm.

Inveresk Precinct manager Robert Groenwegen said the extra tower would also be used to try to attract other sports like A-League back to Aurora.

The tower will get its first test run on Thursday night at the Ricky Ponting Tribute Game.
