Hand Willy and Richmond over to the civilians and pack the RAAF off to Scherger (sp) and Curtin! Give the RAAF controllers based there, the option of switching over to the civvy street no questions asked.
Build some parallel runways at both and there will be more than enough capacity for the Sydney basin for some time to come.
Of course there would be no votes in that, but think of the jobs it would create...
