Joseph Tannous


As founder and Executive Director, Joseph has established the strategic direction and operational structure of the Cornerstone Group based on his experience in advocacy, government relations and public policy making.

Joseph's political career began with his first local council electoral win in 1999, rising to become Mayor within a year.  His active participation in shaping public policy extended to state politics, before stepping down from the Executive of the Liberal Party of Australia (NSW Division) to make the Cornerstone Group the industry leader it is today. 

His negotiating skills and strategic acumen were honed identifying commercial opportunities in international transit and channel management, particularly in China and India. In recognition of his expertise, Joseph was appointed as the youngest ever board Member of the Australian Federation of International Forwarders. 

Joseph brings a passion for advocating positive change with an inherent talent for identifying improvements in political planning and operational techniques. By orchestrating wins at local, state and federal elections, Joseph has developed proactive working relationships with leaders at all levels of the political spectrum. This combination of experience, personal rapport and a natural instinct for what could and should be done to shape public policy has made Joseph a highly regarded advocate and a trusted political advisor. 

In the constant flux of politics at all levels, Joseph focuses on creating and consolidating the lines of communication between business and government that deliver on objectives and achieve results.


Mitch Tanner


Understanding the processes and knowing the key decision makers augment Mitch's achievements, shaping strategic frameworks engaging the private and public sectors.

With a Bachelor of Commerce (Economics) from the University of Melbourne, a Master of Arts (International Relations) from the Australian National University and currently studying law at the University of Sydney, Mitch's academic acumen underscores the practical reasoning and analytical strengths he brings to Cornerstone. 

A decade highlighted by delivering successes in marginal seat campaigns at state and federal levels can be attributed to Mitch's passion for the political arena.  His legislative experience was honed working for a senior Cabinet Minster across the portfolios of Treasury, Finance, Foreign Affairs and Trade, Industry, Innovation and Science, Infrastructure and Transport, Agriculture and Water Resources, Social Services, Resources and Energy and Environment. 

His highly developed understanding for parliamentary procedure was furthered by his tenure with two House Speakers. Prior to that, his time working for a leading ASX200 company developed the basis for understanding how the private and public sectors could align common goals over competing interests.


Brigid Meney


Merging policy innovation with professional and departmental practice is at the heart of the political clarity of thought Brigid adds to the Cornerstone team's capabilities.

Brigid's understanding of political dynamics and policy procedures was shaped during her years at Sydney University where she attained a Bachelor of Arts in Government and International Relations followed by a Masters in Nursing.  Theory was applied in practice as Brigid rose to the status of Senior Political Advisor in the nation's capital. As a medical professional, Brigid concentrated on forging alliances between the national and state health systems building a reputation as an innovative, articulate and successful advocate.

Brigid joined the NSW Department of Premier and Cabinet's Local Government Reform Taskforce. In dealing with the hot-button political issues of council amalgamations across the state, Brigid has developed an intricate knowledge of local partisan dynamics. 

From grassroots election campaigns in some of Australia's most marginal seats to her participation in Australian delegations to the United Nations, Brigid exercises a passion for identifying, planning for and driving change at every level of government.
