Estia Health Ltd. said Andrew Harrison resigned as a nonexecutive director of the company due to competing workload and board commitments.
Harrison joined Estia Health's board in 2014.
The company has appointed Karen Penrose to replace Harrison as a nonexecutive director.
Meanwhile, outgoing CEO and Managing Director Norah Barlow will remain with Estia Health as a nonexecutive director.
Both Penrose and Barlow will stand for re-election at the company's annual general meeting.
Sydney-based Estia Health provides residential aged care services through its facilities and operating places across Victoria, South Australia, New South Wales and Queensland in Australia.
