Pipe dream:
Tax income generated from accumulated wealth the same as income generated from actual work. I.e. a rate somewhere in between the two. No more CGT discounts.
End negative gearing for existing structures.
No more tax breaks for commercial vehicles
Curtail corporations from off shoring profits to tax havens.
Tax on exported gas
UBI

It will be something that in 50 years people will look back on in wonderment at how wrong the DBCA were.
