Yes. Short selling is legal in Australia and regulated by ASIC, the Australian Securities and Investments Commission, which requires market participants to report their net short positions. Naked short selling — selling shares without first arranging to borrow them — is prohibited under section 1020B of the Corporations Act 2001.
Short interest is the total number of shares held short in a stock, usually expressed as a percentage of the company's total shares on issue. On the ASX, below 5% is normal, 10-15% is elevated, and above 20% signals extreme bearish positioning and potential short squeeze pressure.
ASIC publishes aggregated short positions with a T+4 trading day delay, so each report reflects positions held four trading days earlier. The delay gives ASIC time to compile accurate figures, protects reporters from being front-run, and limits the scope for market manipulation.
You borrow the shares through a broker with a securities lending arrangement in place, sell them at the current price, then buy them back later — profiting if the price has fallen. Covered short selling is the only legal form in Australia, and losses are theoretically unlimited if the price rises instead. Read the full guide to shorting the ASX.

Stocks with the biggest short position changes
Over the past week of ASIC short position data to 29 October, short sellers built their largest new positions in Vulcan Energy Resources (VUL, up 1.98 percentage points to 12.18% of shares on issue), Glencore (GLC, up 1.74pp to 17.74%) and Nextdc (NXT, up 1.60pp to 10.74%). Rising short interest signals growing bearish conviction against a stock among hedge funds and institutional investors.
On the other side of the ledger, shorts covered most heavily in Boss Energy (BOE, down 1.38 percentage points to 14.03% of shares on issue), Zip Co (ZIP, down 1.22pp to 14.62%) and Siteminder (SDR, down 0.86pp to 6.74%). Falling short interest can mean the bear case has played out — or that short sellers are locking in profits and reducing exposure.

Substantial holder notices (Forms 603, 604 and 605) disclose a relevant interest in 5% or more of a company’s votes. Why banks and brokers file so many for shares they lend, borrow or hold as collateral, what DroneShield’s 38 notices show, and how to read a register without counting shares twice.
