Astarra has revamped its Australian equity manager line-up for its platform, resulting in the termination of three managers.
Concord Capital, Perpetual and the van Eyk's Blueprint series have all been terminated.
Fidelity International and Integrity Investment Management will replace the three investment managers.
The decision followed an investment review of the firm's Australian equity portfolio.
"The decision to change and appoint new managers is just part of our ongoing review of our investment managers," Astarra managing director Rex Phillpott said.
The firm recently replaced its bond manager Tyndall with Pimco.
Astarra has over $950 million in funds under management.
