List of best-selling singles in Australia
This is a list of best-selling singles in Australia that have been certified by the Australian Recording Industry Association (ARIA). Since 1983, ARIA certifies a single Platinum for shipment of 70,000 copies across Australia. Single figures can include "qualifying streams" since July 2015. Since March 2022 this also includes Official Content streams on YouTube. According to the ARIA rules, a "single" is a product that may include up to five songs, thus including various EPs, which are also listed here. All singles in this list must have won at least 10× ARIA  Platinum Awards (700,000 copies). Prior to 1989, the values of the certifications were different, and a dearth of published data has made it difficult to source earlier release numbers. Entries by artist. Only a few artists have achieved two or more best-selling songs in Australia. The following list includes both works as lead artist and as featured artist.
