Former Prime Minister Scott Morrison has been described as “one of the most consequential world leaders of the last decade” by the boss of the global advisory firm he’ll be joining in his post-politics career.

Mr Morrison announced on Tuesday that he was quitting politics to take up “a series of global strategic advisory roles and private boards, focused on the US and Indo-Pacific” and drawing on his experience and networks in the region, in particular through AUKUS and the Quad diplomatic partnership.

American Global Strategies, an international advisory and consulting firm headed by Trump-era security adviser Robert O’Brien, confirmed on Wednesday that Mr Morrison will join the company as non-executive Vice Chairman.

AGS says on its website that it assesses global geopolitical opportunities and risks, develops strategies to help clients navigate US government processes, provides guidance on international business transactions and assists with crisis management.

Mr Morrison said he had enjoyed a great working relationship with Mr O’Brien in the past and looked forward to working with him again, especially in the Indo-Pacific.

“Together we can draw on our combined networks and experience in the region to help clients navigate a highly dynamic geopolitical landscape that presents risks and opportunities,” he said.

“And it’s not just in the defense and security space. Supply chains, technological change, resource security, energy transition and new types of partnerships between the private and public sectors are all impacted by the world becoming an ever more complicated place.”

Mr O’Brien described Mr Morrison as one of the most consequential world leaders of the last decade, who presided over unprecedented changes to the nation’s foreign and defense policies.

“As American Global Strategies’ non-Executive Vice Chairman, Prime Minister Morrison will bring high-level relationships and unique geopolitical insights to our clients,” he said.

Mr Morrison said he will leave parliament at the end of February and will be spending more time with his family in Australia.

Prime Minister Anthony Albanese thanked Mr Morrison for his service.

“ I spoke to Scott Morrison yesterday. I wish him well,” he said on Wednesday.

According to media reports Mr Mr Morrison will also work as a strategic adviser to asset management firm DYNE Maritime alongside former US Secretary of state and ex CIA director Mike Pompeo.
