A lot of this seems to be coming from an ideological push by certain individuals in the Government (eg Andrew Robb and Joe Hockey). Fair enough, but if we're going to be ideologically pure, let's extend it to government as well. Surely there are other countries which are better-governed than Australia, and other countries whose politicians are much cheaper than ours - none of those generous superannuation entitlements, travel and accommodation allowances, and so on. So as well as domestic aviation, let's outsource our goverment overseas as well. I'm sure Andrew and Joe won't mind a bit.
