I am advised:

The cost of bill are the main issue raised in these complaints.

The  Government is implementing a range of measures to assist households and businesses reduce their energy costs. This includes:

• implementing the Energy Affordability Package, which included increasing all rebates by 20 per cent. The Low Income Household Rebate, which is open to many concession card holders, has increased from $235 to $285 per year per household. The Family Energy Rebate has increased from $150 to $180 per year per household, and the Gas Rebate has increased from $90 to $110 per year per household.
• abolishing unnecessary retailer fees from 1 January 2018. The prohibition on early termination fees, paper bill fees and fees for paying through Australian Post outlets can save customers up to $30 per year.
• implementing a $72 million package of energy efficiency measures to enable households and businesses to use new technology to reduce their energy costs. This includes $24.5 million for upgrades to more than 20,000 rental homes for energy efficiency lighting, heating and hot water systems.
• rolling out a $15 million Solar for Low Income Households trial program, providing solar panels to low income households to help them reduce their electricity bills. Up to 3,400 households will be able to save up to $300 each year on their bills.
• developing Energy Switch, a free service which helps customers find a better energy deal and initiate the request to switch retailers. Through a comparison tool, customers will be shown the best priced plans from retailers based on the usage detailed in their current bill. Customers can then initiate a switch to a preferred energy retailer, based on their preferences.
