AustralianSuper gained $8 billion in assets and in excess of 112,000 members over the year making it the fastest growing superannuation fund in Australia.
The fund has more than $28 billion in funds under management.
Research from SuperRatings showed that out of the top ten largest funds, nine were industry and government funds.
AMP Corporate Superannuation was the only retail fund netting $2 billion in assets over the year.
Along with AustralianSuper, the top five funds that dominated in size were UniSuper, QSuper, Sunsuper and Hesta.
Two of the largest increases came from funds that were not opened to the public including Unisuper and QSuper. Both gained $4 billion in funds inflow over the year.
"This makes their growth efforts even more exceptional," SuperRatings managing director Jeff Bresnahan said.
Industry funds Rest and Hostplus also won the largest share of new members, gaining 107,000 and 98,800 respectively.
"It is clear that Australians are more than ever embracing superannuation as a genuine savings vehicle," Bresnahan said.
He warned, however, that if investment markets go through a negative cycle then Australians' "general apathy towards their superannuation may turn around overnight".
"This should provide warning signs to those funds that have experienced less than average growth in recent times," he said.
