three main reasons
1. Rooftop solar has cut the costs of electricity when the sun is shining in Australian cities
2. Transmission costs to get it from where its generated (Woop Woop) to where its needed (Sydney, Melbourne, Brisbane)
3. Storage costs – this is coming down and large batteries are currently being planned and installed in the location of existing infrastructure, I.e. old coal fired power stations that are being closed
Should also mention that there is a large solar farm in planning for the Northern Territory, Sun Cable, which will feed electricity to Singapore and beyond
