Alternative milk company a2 Milk said exceptional growth in its infant formula sales had driven its net profit to $30.4 million in the year to June from a $2.1m loss a year earlier.
Total revenue came to $352.8 million - an increase of 127.4 per cent over the previous corresponding period.
The company - which uses A2 beta casein protein-type milk to the exclusion of the more mainstream A1 protein equivalent - said there had been continued growth in the Australia and New Zealand market, and in China.
"The Australia and New Zealand business achieved exceptional growth in a2 Platinum infant formula products, with continued steady volume growth in a2 Milk™ branded fresh milk and initial sales of a2 Milk™ branded whole milk powder," a2 Milk said in a statement.
Sales of a2 "Platinum" infant formula in China grew strongly, and the China and other Asia business delivered positive operating earnings for the first time since the company entered the China market.
