An invitation-only CEO cohort shaping business leadership in South Australia

1839 South Australian Business Chamber



The South Australian Business Chamber exists to provide an independent, representative voice for business — fostering a strong and connected business community and lifting leadership capability across the state. This work is delivered through our four pillars: Advocacy, Policy Engagement, Events, and Connection, and is enabled by membership revenue, which funds the Chamber’s ability to convene leaders, influence, and invest in initiatives that support South Australia’s economic environment.

1839 Membership is the South Australian Business Chamber’s premier, invitation-only CEO cohort. It brings together a select group of senior business leaders to engage in trusted conversation, influence outcomes, and help shape the future of business in South Australia.

The cohort is intentionally small, ensuring depth of discussion and meaningful peer connection.

Who is it for?

Membership is by invitation to:

  • CEOs, Managing Directors, and business owners
  • Leaders of major South Australian organisations
  • Executives seeking a confidential, peer-level forum
  • Decision-makers interested in thought leadership and policy influence

Our purpose

1839 exists to:

  • Provide a trusted environment for senior leaders to exchange ideas
  • Deliver a tailored program of thought leadership shaped by member priorities
  • Strengthen the voice of business in government and public discourse
  • Influence economic, workforce, and regulatory outcomes in South Australia

A curated approach

Each year, the 1839 program is shaped around the priorities of the cohort, with content, speakers, and discussions carefully curated to create relevance and impact for the group.

What members value

  • Access to an exclusive CEO peer network
  • A tailored thought leadership program
  • Confidential, top-level discussions
  • Direct engagement with policymakers and influential leaders
  • Opportunities to contribute to advocacy and policy

Why 1839 is different

    • Peer-level engagement, not transactional networking
    • Invitation-only membership, subject to board approval
    • Focus on leadership and contribution
