Retention.
Why did half of 1 Bde move to Edinburgh from Darwin? Wasn't just for proximity to Cultana for year-round range access. When it was announced the ADF was in its mid-2000s tempo reduction, mining boom on, ADF members pulling the pin in droves. Then Minister Robert Hill was quite open about Adelaide being a 'respite posting'.
Now trips to the MEAO are winding down, Defence will have to start re-examining how to keep critical people in the job. 'Suakin' is part of it, but so is paying attention to why people get out altogether.
My theory anyhoo
