TelstraSuper Chief Executive Officer, Chris Davies thanked Mr Miller for his leadership and significant contribution to the fund.  

"Graeme has played a pivotal role in shaping our investment strategy, delivering strong outcomes for members and driving the fund's approach to sustainable investing," said Mr Davies. "On behalf of everyone at TelstraSuper – and our members – I want to sincerely thank Graeme for his dedication, commitment and expertise. We wish him the very best in his next chapter."
