To convert ml to oz in Australia, use the US fl oz factor (0.033814) for international products, or the Imperial fl oz factor (0.035195) for older Australian recipes. Australia fully adopted the metric system in 1970 and uses milliliters exclusively on product labels — but vintage Australian cookbooks still reference Imperial fluid ounces.
View Australian Conversion FormulaAustralia completed its metrication in 1970 under the Metric Conversion Act, making it one of the most thoroughly metricated English-speaking countries. All Australian products, recipes, and official documents use milliliters (mL) and liters (L) exclusively.
The Australian metric cup is 250 mL, and the Australian tablespoon is 20 mL (larger than the US/UK tablespoon of 15 mL). These unique Australian metric measures can cause confusion when converting international recipes.
Modern Australia does not use fluid ounces on any product labels or in official measurements. However, older Australian cookbooks (pre-1970s) used Imperial fluid ounces (28.4131 mL) from Australia's British colonial heritage.
When Australians encounter fl oz on imported US products, those are US fluid ounces (29.5735 mL). When converting "nan's old recipe," use Imperial fl oz (28.4131 mL).
Drag the slider to see common Australian product sizes. Australian beer cans are 375 mL — larger than American cans (355 mL).
Australia uses metric, but when converting to fl oz, use the US factor for imports or the Imperial factor for vintage recipes.

No. Australia fully adopted the metric system in 1970 and uses milliliters (mL) exclusively on all product labels and in all official measurements. Fluid ounces only appear on imported products (usually US fl oz) and in pre-1970s vintage recipes (Imperial fl oz).
When Australia metricated, it chose 20 mL for the tablespoon to be a rounder metric number (4 teaspoons of 5 mL = 20 mL), rather than adopting the US/UK tablespoon of 15 mL (3 teaspoons). This means Australian recipes with "1 tablespoon" use 33% more liquid than US recipes — always check which system the recipe uses.
An Australian beer can (stubbie) is 375 mL ≈ 12.68 fl oz, slightly larger than a US soda can (355 mL / 12 fl oz). A "long neck" is 750 mL (25.4 fl oz), and a "tallie" is 750 mL. Australian beer is sold exclusively in metric sizes.
Old Australian recipes (pre-1970s) use Imperial measurements. Use these conversions: 1 Imperial fl oz = 28.4131 mL, 1 Imperial cup = 10 fl oz = 284.131 mL, 1 Imperial pint = 20 fl oz = 568.261 mL. Do NOT use US fl oz values for these vintage recipes.
1 Australian cup = 250 mL (metric cup). This is the same as the metric cup used internationally, but different from the US cup (236.588 mL) and the old Imperial cup (284.131 mL). Modern Australian recipes use 250 mL cups.
Australia passed the Metric Conversion Act in 1970 and the Metric Conversion Board oversaw the transition through the 1970s and 1980s. By the late 1980s, metrication was essentially complete. Australia is considered one of the most successful metrication examples worldwide — Imperial units are virtually absent from modern Australian life.
