Are you in South Australia ?
I found with a search SA with this available to many households on some sort of Govco payment / health card, there might be other states also offering such rebates.
If you are in SA, info here . . .
https://www.sa.gov.au/topics/care-and-support/concessions/household-concessions/energy-bill-relief
It says if you already get an energy concession . . .
"You don’t need to do anything. You should already be receiving the bill relief as a quarterly credit on your electricity bills this financial year, in addition to your energy concession.
Look for a description like AUS SA Gov Energy Relief on your bills. If you’re billed monthly, you’ll see the credit approximately every 3 bills.
Your eligibility will be assessed again on 30 April 2024. You’ll continue to receive the bill relief if you remain eligible on this date."
