From my knowledge of the Australian census and what I can find on the Australian Bureau of Statistics website, we don't have this information about Australians either. It seems we don't know what other languages people can speak. The only statistic available is *households* which speak a language other than English, which greatly under-estimates the ability of any individual to speak that language as it depends on who they are living with and fails to tell us how well that other language is spoken by any individual.
This issue came up for Australian Wikipedians in connection with Indigenous languages. Despite the fact that we get asked to provide information on Wikipedia on the number of people who speak either any Indigenous language or a particular Indigenous language, we have no ability to answer that question except for whole households. And since (depending on how you define "language") there were 250+ Indigenous languages (with even more sub-dialects), even a household entirely composed of Indigenous people may not have a common Indigenous language to speak at home.

I usually have a very hard time finding such data from official/reliable sources, even for EU languages. (I usually search for CLDR purposes.)
