The Carbon Tax was inevitable in Australia and is a good measure towards reducing carbon emissions with a view to mitigate global warming. I support the Carbon Tax and other moves to deal with climate change.
Getting back to the original topic. See my post higher up on this page. The Carbon Tax has a negligible effect on Australian aviation.
There is no real financial cost, the real cost is time wasted talking about the Carbon Tax in anonymous internet forms.
