MELBOURNE, Feb 15 - The Independent Broad-based Anti-corruption Commission (IBAC) is investigating past and present senior Department of Education bureaucrats and the botched Ultranet schools computer project, which was scrapped in 2013.

The hearing is examining relationships between mostly former staff and companies awarded contracts to deliver Ultranet - and whether they received holidays and gifts during the tender process.

Senior education department officials also allegedly bought shares and took jobs with the company that was given a $60 million contract for the project.

The scheme, initiated under the Brumby Labor Government, was scrapped by the Napthine Coalition Government in 2013 when costs blew out from $60 million to $180 million.
