The electricity grid was sold off to get money for making tollways toe sell etc.
I worked on a Victorian Power Station control system upgrade circa 2000. At that time the SECV (Victorian state owned power authority) for a very large amount of money, in fact they overpaid by about 100%. The Company that bought it quickly realised that they had overpaid and let the industry know. Seeing how much money that Victoria had got ever other state in Australia tried to sell their power system, but the industry had woken to the little money that they would make and were not interested. So to be able to sell the NSW system a Poles and wires upgrade was initiated. A few future possible use substations were built but the Poles and Wires (all very reliable) campaign was stated, a huge increase in the cost of electricity was then applied, we all groaned but paid it. These new rates changed the profit margin that an authority could make. The industry flocked to buy it. They are making a mint. My data from 2019 was that electricity bulk average rate was $0.14c/kwh, most us pay around $0.33c/kwh. Ok there are expenses but that is a nice profit for using computers to buy and sell electricity. The sale of the NSW electricity commission was essentiall an ongoing pseudo tax on NSW residents courtesy of the politicians. Similar to Tollways etc.
When I bought my Cherokee in 1983 I just paid an Air Navigation Charge (the name may have been different as my memory is not good). For that charge I got all my government landings, documents and administration for free. Now everything costs way more than it costs them so that they can return money to government coffers. Airports given by the government to local governments quite often saw the real estate being sold to fill the local government coffers, more often than not wasted.
