what percentage of australians are left handed

About 10% of Australians are left-handed. A 2025 Australian source also describes left-handers as “the 10 per cent of left-handed individuals in Australia,” which lines up with the broader global estimate of about 10.6%.

Quick Scoop

• A solid rule-of-thumb is 1 in 10 Australians.

• Global research puts left-handedness at about 10.6% overall.

• Rates vary by country, so Australia is around the high end of the typical range rather than an exact fixed number.

Why it varies

Left-handedness is not identical everywhere. Research notes that rates can range roughly from 3% to 12% across countries and regions. That means Australia’s share is best treated as an estimate, not a precise census-style figure.

Bottom line

If you want the short answer: about 10% of Australians are left-handed.
