This is just me reading between the lines but I suspect that post election and providing the Libs win there win be a tightening of ng . It might not be rule changes as such but it might be the tax office scrutinising claims more thoroughly for example .
I only caught a quick glimpse of the news but I heard MT saying that housing prices was a supply and demand issue . So I look forward to further announcements as to what they might do about it .
Might be satellite cities , faster and better transport , better NBN etc in order to help take the pressure off the big centres ?
