A mate of mine whose membership seat is next to me got an email a week ago saying planned works meant that his seat would be unavailable due to work to be undertaken at the MRS and therefore his seat would be moved.
Strangely myself and another friend who both sit next to him did not get this email.
To me the email indicates that matches will still go ahead at MRS and not be moved to Casey Fields.
Also $25M doesn't get you much in the way of "works" in Victoria these days (maybe MRS is simply having an aboriginal flag installed...).
