GovHack provides participants access to open government data, with a view to that data being utilised for the betterment of Tasmania.

Information Technology Minister Michael Ferguson said more than 270 government datasets had been made available.

He said participants were developing such tools as websites and apps.

A new prize is on offer for the best use of heritage data, in addition to the Most Outstanding Tasmanian Benefit and Most Commercial Benefit prize categories.

Mr Ferguson said he was looking forward to seeing the ideas participants came up with.
