The people best placed to deliver you Better Board Performance.
Who we are
Global Governance Advisory (GGA) is a group of specialist Board and Governance advisory firms. GGA has access to a network of specialist advisors that is unrivalled for its breadth and diversity. Our people are unsurpassed in their wide-ranging experience, insight and expertise.
Under the GGA umbrella, we bring together the extensive experience and expertise of Australasia’s leading board and governance organisations: Peakstone Global Pty Limited in Australia and Westlake Governance Limited in New Zealand.
Our capabilities extend to supporting any governance-related requirements you may have, regardless of the industry, sector or market you operate in.
While we are firm believers in best practice, our real-world experience ensures you won’t be offered a formulaic or purely theoretical approach to your challenges, regardless of their complexity.
