Tim Soutphommasane said that while Australia's cultural diversity was to be welcomed, equality of opportunity in the top echelons was lacking.
In a speech entitled "The Asianisation of Australia?" delivered late yesterday, he said children of Australians from migrant backgrounds outperformed native-born Australians in education and employment.
"Progress, though, is never complete. Our achievement is not quite perfect," said the commissioner, a first-generation Australian with Chinese and Lao roots.
"Because while Australia does extremely well in social mobility for immigrants, including those from Asia, equality of opportunity isn't enjoyed in equal measure in all spheres.

"Our cultural diversity is far from proportionately represented in positions of leadership."
As an example, Soutphommasane said that while around one in 10 Australians had an Asian background, there were only four people with Asian origins in the national parliament. There are also two Aborigines, but the rest have European ancestry.
"In percentage terms, only 1.7 percent of those who sit in the federal parliament bear an Asian cultural background," he said.
It was a similar scenario in senior leadership at Australia's educational institutions, with only two people of Asian background among the 49 senior executives at the top eight universities, his speech to the Asian Studies Association of Australia said.
It showed that only 1.9 per cent of executive managers and 4.2 per cent of directors had Asian origins.
