Pearce really needs to be shut down.
Whilst I appreciate the airspace problems caused by Pearce, I doubt it's going to be closed any time soon, given the size of the RAAF/RSAF training operation. Where do you propose they go? It would take a huge amount of money to upgrade Learmonth for the task, something that's not likely to happen in the current budget environment. Further, closing Pearce would severely limit the air support options for other defence units based in the Perth area.
