ACTU president Michele O'Neil had told the commission a six per cent rise was within a band of increases that would not constitute a threat to economic growth.
On Thursday, the ACTU's assistant secretary, Liam O’Brien, said the rise was a "step in the right direction".
But he said it would still leave the minimum wage more than seven per cent short of the living wage target, which is 60 per cent of the median full-time wage.
“We have a long way to go to ensure that the minimum wage is enough for workers to live on and support their families," O'Brien said.
“No one in Australia should be living in poverty while working full time, but we know that thousands of people are facing this reality."
The Australian Industry Group was calling for a rise of two per cent or about $14.40 a week, while the Australian Chamber of Commerce and Industry asked that the increase not exceed 1.8 per cent.
The pay rise will take effect from the first pay day after July 1.
