What ICMS Pty Ltd does

ICMS Pty Ltd is an Australian family-owned Professional Conference Organiser (PCO) headquartered in Cremorne, Melbourne, established in 1971 when Barrie Markey partnered with Lin Knight to deliver conferences on behalf of client associations. The company offers end-to-end conference and event management services, including registration management, venue sourcing, speaker and program coordination, financial management, marketing and promotion, exhibitor and sponsorship procurement, travel and accommodation (via wholly-owned subsidiary ICMS Travel), strategic advisory, and event technology delivery. Its principal client base comprises professional associations, healthcare and medical societies, government bodies, scientific organisations, and educational institutions across Australia, with several multi-decade client relationships including the Community Broadcasting Association of Australia, Australian Society of Antimicrobials, and Australian Central Association of Dentists. ICMS has delivered over 850 events and claims that 100% of conference budgets it manages return a profit to clients.

The company's technology stack centres on EventsAir (and its OnAIR module) as the preferred event management platform, with ICMSconnect — a virtual and hybrid events platform launched in 2020 during the COVID-19 pandemic — built on top of OnAIR to support virtual registration portals, conference websites, mobile apps, virtual exhibition halls, networking sessions, live Q&A, polling, and ePoster presentations. ICMS is accredited by the International Association of Professional Congress Organisers (IAPCO, member since 2003) and holds memberships in the Professional Conference Organisers Association (PCOA, 2025), the Australian Business Events Association (ABEA), and the International Congress and Convention Association (ICCA). CEO Sarah Markey-Hamm, daughter of founder Barrie Markey and a 30+ year events industry veteran, served as IAPCO President (2023-2025) and now sits as Immediate Past President while chairing the IAPCO Committee of Ethics.

ICMS operates as a privately held professional services firm with no disclosed external funding and a small team (1-10 employees). Revenue is generated through custom professional service fees on a quote-based engagement model, with transparent financial management and no hidden commissions or mark-ups. New client acquisition is driven primarily by industry reputation, word-of-mouth referrals, the CEO's international industry leadership positions, and direct outreach anchored by a free consultation offering. Geographic focus is Australia-domiciled with international affiliations, serving clients whose events span Australia, New Zealand, and Asia Pacific.

Broad incumbents

• Kenes Group: One of the world's largest PCOs headquartered in Geneva with strong medical/scientific association focus. Competes with ICMS for healthcare and scientific association clients in the Asia-Pacific region, but operates at materially larger scale globally.

Direct peers

• Arinex Pty Ltd: One of Australia's largest PCOs, headquartered in Sydney. Directly competes with ICMS for association and healthcare conference mandates across Australia with similar end-to-end PCO service offerings.
• All Occasions Group: Adelaide-based PCO offering full-service conference and event management to associations and corporates across Australia, directly competing with ICMS in the domestic PCO market.
• Conference Associates International (CAI): Australia-based PCO with similar end-to-end conference management services targeting associations and professional bodies in Australia and the Asia-Pacific region.
• ASN Events: Australian PCO with similar association and healthcare conference focus, comparable size and service portfolio to ICMS, competing head-to-head for Australian association event mandates.
