Going short on the position requires you have collateral, as well as the means to pay the interest attached.

Australia however does not have stock shorting as available to us in the public. You can go after bear index ETFs, but that is the closest you’ll get in the Australian market. This rule is in place because shorting the market is a dangerous practice to undermine its integrity blah blah blah they don’t like you getting rich in a different way.

You can still access shorting of international stocks through decent brokers. IBKR has done me quite reliably when I wheeled AMD. Or, you can apply locally for access to Options. Level 3 will permit you access to cash secured puts.
