negative gearing

"The Affordable Housing Party: the single issue party dedicated to solving Australia's housing affordability crisis. Australians are now living with some of the most unaffordable housing in the world, but it doesn't have to be this way! Obscene tax incentives to invest in property. Our lawmakers profit from the status quo. We opened up our housing market to investors all over the world.

At first glance The Australian Greens’ announcement that they would abolish the negative gearing ₁  tax break, in a bid to increase government revenue through increased taxation and improve homelessness and housing affordability looks like the right move. I have, however a few questions about this.
