Water supply and quality provenience branding will be Tasmania's competitive advantage as leaders look to grow the state's $500 million dairy industry.
Mr Beca was appointed in July, 2015.
An executive search to replace Mr Beca has been launched with Mr Beca will remain to assist with the transition to a new CEO.
Moon lake deputy chair, David Crean, said plans to export to China would not be affected.
“Moon Lake, through its sister company Van Dairy, is pushing ahead strongly with its plan to export
fresh Van Milk directly from Hobart to Ningbo in China under the partnership we announced with
Qantas in November 2016,” Dr Crean said.
Mr Beca said he was leaving because his role had changed from CEO to more that of a chief operating officer following the acquisition by Moon Lake.
“This is not a reflection on Moon Lake which has its own structure with Managing Director Mr Sean
Shwe taking a leading role in value-adding to the VDL brand by developing the Van Dairy brand and
marketing our product in China,"Mr Beca said.
