Changes to the national minimum wage are reviewed annually by the independent Fair Work Commission (FWC), which last year delivered an increase largely in line with inflation.
"If the Fair Work Commission makes that decision then I would welcome it, but it is an independent decision of government.
The FWC decision, expected in June, also covers minimum wages and conditions for specific industries and occupations, known as awards.
Roughly 2.7 million Australians are covered by awards, compared to around 180,000 on the minimum wage.
Catherine Birch, a senior economist at ANZ, said the FWC would likely lift the minimum wage further than award wages, given the latter's broader reach.
