Johnstaff is a specialist advisory and project management consultancy with over 30 years of experience successfully delivering a diverse portfolio of projects and services for private and public sector clients. Established in 1991 by Phil Johnston and David Wagstaff, they identified a gap in the market to provide independent project advice based on their hands-on delivery experience from careers working with Tier 1 contractors. Today, our teams focus on providing commercially viable, value-enhancing solutions to our clients’ business, project, and investment needs. We have over 250 professionals across eight offices in Australia and New Zealand: Melbourne, Sydney, Brisbane, Perth, Geelong, Auckland, Wellington, and Christchurch.
