Lappers, short selling has been around for ages under govts of all persuasion including Greens supporting Labor, So it is NOT a Morrison Govt thing. Labor could have done what you want but nah and unlikely to do much in the future except tinker at the edges. The area you are discussing is extremely complex and cannot be discussed in a forum such as HC IMO. Suffice it to say that short selling has a place in portfolio management and can be shown to be good for the market.
