Yes Definitely Tax gas..
But, the rest of this sounds like crap
I've never been to a public hospital that wasn't free. I went to the GP twice in the past 2 weeks.. Free. When I was hit by a car.. FREE. Even Flying doctors from my understanding are free, and we now have urgent care clinics too to free up hospital resources (and, pharmacists can do vaccinations, to further free up resources).
We have cheap drugs, and its so cheap, that Trump was trying to strong-arm Australia into raising their prices. And, a lot of free vaccinations
Public schools are also free (although, I went Private)
We have one of the best health care systems on the planet, and its actually admired by a lot of countries (just like our gun laws). Dental is the only thing not free
The whole "we've had enough" tagline sounds like something Pauline or Nationals would scream honestly (and, I suspect most Aussies have had enough of them). We're actually doing better than those guys want people to believe.
But, yes, other than that, I want Gas to be taxed, and then use the money for electrification for full long term energy independence thats clean.
