Mr Alcock confirmed the departure in a statement, saying that Mr Gillett had been a beneficial addition to the team.
“We wish Wes well for his next endeavours, he has made a positive contribution to the business over the past four years,” Mr Alcock said.
The company is currently searching for a “suitable replacement” for Mr Gillett, and in the intervening time has appointed George Deva and Greg Newman to the role in an acting capacity.
Earlier this month, Hub24 added the Australian Unity Diversified Property Fund to its Investor Directed Portfolio Service platform.
