And I can, and probably will, be corrected because I don't know for certain, there hasn't been an "aviation minister" in Aust for quiet some time. All have had joint portfolio's which means all haven't given 100% to the job.
The last Minister for Aviation was: Peter Morris 1984 - 1987
Of the estimated 50% effort they did put in, only The National Party with roots in the bush did anything constructive. (I'm not sure about Truss though).
I'm not sure about Anderson either!
