MILDURA'S theatre groups have been snubbed in the latest developments in the revamp of Mildura's riverfront Powerhouse, with rehearsal and performance spaces excluded from the list of ideas Mildura Council says it is considering for the site.

Mildura Theatre Company (MTC) and Musical Society Mildura (MSM) called the Powerhouse home for more than 50 years, before being kicked out of the building last year due to structural concerns.
