The big four firm announced that it has substantially acquired the assets of Casey Quirk, which it describes as "the world’s largest strategy consultancy devoted exclusively to serving the asset management industry".
Its partners and existing team will transition to Deloitte and operate under the 'Casey Quirk by Deloitte' brand.
"This acquisition cements the strong position and global reach that Deloitte enjoys in the Australian and global asset management markets," said Neil Brown, Deloitte Australia wealth management leader.
"With Australia being one of the largest asset management markets in the world, the acquisition of Casey Quirk will be extremely valuable to our clients in this market.
"Casey Quirk has a great name here, and as our super pool of assets increases over time having asset management specialist skills that are globally relevant is becoming increasingly important."
Casey Quirk chairperson Kevin P Quirk said the firm’s move represents an intention to broaden international reach.
"Casey Quirk is joining forces with Deloitte to broaden our global financial services footprint and deliver differentiated execution capabilities for our clients," he said.
"This combination provides an unparalleled value proposition to the marketplace."
