Humphrey joins Hillross from Singtel Optus where he was director of mobile and convergence, and responsible for its integrated mobility offerings for corporate and government customers.
AMP director of financial planning, advice and services Steve Helmich said Humphrey would be charged with growing the Hillross business in an increasingly competitive market.
"Hugh's appointment will bring a fresh approach to the Hillross business," Helmich said.
"His extensive sales and marketing experience with some of Australia's largest and most competitive companies will ensure Hillross is well placed for future growth."
Prior to joining Optus, Humphrey spent six years with Vodafone in a number of senior roles, including general manager for business markets and general manager for people and brand.
He started his career as a management consultant at PricewaterhouseCoopers and later with IBM Business Consulting Services after its acquisition of the PwC Consulting business in 2002.
Humphrey replaces acting managing director Ray Djani, who will continue in the position until Humphrey joins.
