Reading between the lines it seems likely the cost of moving a grandstand would be prohibitive. It's a large building! Then there are the ongoing costs of maintaining the building away from club premises.A solution for everyone, including the possums.
Move the stand to Kevin Barltlet Reserve.
In some ways it would've been an easier decision in its former run-down state. If there are any feasible solutions then I'm sure interest groups will raise them before the bulldozers move in.
