A lot of this is politics relating to gas prices. it's looking likely an opposition govt will return to power who are more green party associated like with in policy, an example is like you say in Victoria where fracking is going to be banned permanently. The assault on fossil fuels will only increase as these parties take control, but the prices will continue to rise, they know they cannot force prices down, just offer alternative sources of renewable.
But the numbers tell a different story when added up at the end of the day with that stuff, the want to be green totally and the want to save the planet will collide with the old supply and demand scenario, and then it will be too late.
Gas prices are set to sky rocket again and again as like you say protestors become more vigilant, unless demand stops and that's pretty unlikely in the next 5 years.
Selective gas investment is good thinking for future return.
