Australia, despite being often equal largest gas exporter and massive coal importer (an energy super power) has the highest gas and electricity prices charged to its citizens compared to the US/UK/etc. IMO a lot of it is due to local corruption of politicians.

As an example there is a nice trade for Asian gas importers at the moment where they buy Australian gas and Australian's import it by from them (the surplus they don't use) and they take an arbitrage profit. The stuff they do use powers a lot of manufacturing from what I understand. Australia is even building gas import terminals right now to take pressure of local energy prices because the global market has better pricing than locally (despite being one of the cheapest places to produce and/or mine energy). A massive government policy failure; unlike Norway and other energy sovereigns.

This high price has the silver lining of making a renewable transition viable as gas power in particular becomes extremely expensive despite Australia having one of the most lowest cost gas and coal production globally. Of course its people are paying for that in their cost of living, and decline in manufacturing due to high energy prices.

I wouldn't look to Australia for anything w.r.t energy policy and what you should do. With the energy abundance they have (rivaling some oil states) - a lot of commentary locally there stating that if Australia just had its energy policy adjusted a little bit before now they could of been one of the richest countries per capita globally. They've royally screwed things there IMO.

There is a lot of gas in the US.

The Navajo Power Plant near Page, AZ closed a few years ago largely due to economic reasons.
