Some of Australia's top finance deal makers have been recruited to run a new full-service broker and investment bank backed by ASX-listed fund manager Magellan Financial Group and British bank Barclays.

A star-studded line-up, including three ex-UBS Australia executives, will head up Barrenjoey Capital Partners. It will offer corporate advice, equity and debt capital underwriting and research and brokerage.

Barrenjoey is led by former Challenger managing director Brian Bernari, who becomes chief executive, and former UBS executive chairman Guy Fowler who takes the role of chairman. Ex-UBS investment bankers Matt Hanning and Chris Williams are founding partners as well as John Cincotta, a former Deutsche Bank executive.

Ken MacKenzie, the chairman of BHP and former chief executive of Amcor, will join in early 2021 as a senior strategy partner. Cynthia Whelan, who has held executive positions at Scentre Group and Telstra, is a senior adviser.
