The CEO of the new entity is Nick Morris, founder of London Economics and the chief executive of Tasman Economics since 2000.

"This is an exciting new creation that could greatly strengthen economic, business and government reform agendas in all areas in the region," said the new executive chairman Dr Michael Porter.

"Current crises such as water and Asia-Pacific governance, as well as energy, regional Australia, transport and environment issues will be well served by the new group."

David Trebeck, founder and CEO of ACIL Consulting and executive chairman (Canberra) of the new entity, said he was delighted at the possibilities ACIL Tasman now created.

"The many and increasing governance problems in the public and private sectors suggest that ACIL Tasman is timely - a genuinely independent group with substantial experience within the corporations and governments of Australia and the region," said Trebeck.

"ACIL Tasman has strong expertise in regional and agricultural issues, energy, transport, health, infrastructure access, defence and government relations, among many other fields."

The new entity will have its head office in Melbourne, with major offices in Canberra, Brisbane, Sydney and Perth.
