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 28 October, short sellers built their largest new positions in Glencore (GLC, up 2.43 percentage points to 18.84% of shares on issue), Zip Co (ZIP, up 1.78pp to 14.94%) and Vulcan Energy Resources (VUL, up 1.33pp to 11.23%). 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 0.93 percentage points to 14.27% of shares on issue), Telix Pharmaceuticals (TLX, down 0.72pp to 10.33%) and Polynovo (PNV, down 0.66pp to 6.67%). Falling short interest can mean the bear case has played out — or that short sellers are locking in profits and reducing exposure.
