It's true, oz covers a huge area and that doesn't help. And we certainly aren't going to get Autobahn-quality roads for interstate routes
Out of interest sake its the tax payer plus additional loans who funds all government expenduture.
^^^ It's the "plus additional loans" that should be of concern here. The fact that Oz national debt keeps increasing means... (pause for drumroll...) we aren't paying enough tax. Currently, Oz is doing the equivalent of living off a credit card - and that can't last forever.
It's also true that our dipshit politicians have sold off a bunch of revenue-producing assets (Telstra, Medibank Private, Commonwealth Bank just to name a few) which leaves us poorer in the long run. It's also true that our immigration policy is allowing in a large number of people who are a drain on the economy. A case in point: parent visas.
… parent visas, which provide a short-term benefit to the budget via visa charge income, but impose very large costs in the longer term through their impacts on expenditure on health and aged care, and social transfers. In previous work, the Commission estimated the budgetary costs associated with the 2015-16 parent visa intake alone to be $2.88 billion in present value terms over the lifetimes of the visa holders. By comparison, the revenue collected from these visa holders was only $345 million.
So, in return for a one-off payment of $345 million for the yearly intake, Oz gets saddled with a long-term obligation of nearly $2.9 BILLION. That's a net cost of $2.5 BILLION per year. I wonder how much road you could build with that? Or how much you could do for our aged pensioners who have contributed taxes for their entire lives?
