Mr Jeffers stepped into the new Sydney-based role of divisional director, financial services at the advisory firm in February, according to a statement.
He makes the move after more than 10 years at Westpac Group and St.George Bank where he held a number of manager and director roles, such as relationship manager, professional services and associate director, financial institutions and banks.
Most recently, he was the sector head of insurance relationships for financial institutions at Westpac Institutional Bank, a role he held for nearly two years.
Mr Jeffers reports to Willis Towers Watson financial solutions managing director, Asia-Pacific Stuart Ashworth, who said the team was delighted to welcome him.
“Jamie has significant experience working with Australian lenders, and understands how the insurance market can interact with, and complement, their distribution strategy,” Mr Ashworth said.
“Leveraging our global expertise, Jamie will provide guidance and assistance to both international and domestic clients in Australia, allowing those clients to understand and access insurance capacity and capital.”
