After a number of years in senior management, Graham commenced his consulting career in 1989 with National Benefits and Consulting Group. Here he acted as company actuary to FML Assurances Ltd, Associated National Life Co and APA Life Assurance Limited.

In 2000, Graham became Sydney Manager for Eriksens Actuarial Pty Ltd, where he would work for the following eight years.
