They're phasing gas out in Australia now. It's not allowed to be installed in any new homes and they'll start systematically converting older homes sometime soon. Gas was never all that common in my state anyway although I have no idea why, most homes here are electric only, it's going to be a big job in the eastern states though.
They're promoting the public health and safety dangers of gas but it's also part of our environmental plans for the future, we're slowly phasing out fossil fuel mining too. I only found out the other day, we're aw bigger fossil fuel supplier than the United Arab Emirates.
I'm surprised that your government is phasing out gas for the entire nation. Here in the USA, some cities have banned gas stoves and heating in new construction. The infrastructure to plumb and maintain gas lines all over the place is much more expensive than running electric power lines everywhere.
