The difference is our people

About Us

Highly Experienced Practitioners

OCM operates a different delivery model to that of our competitors. We only employ practitioners with substantial experience in their area of expertise. Each practitioner is a leading expert in his or her field and has a minimum 10 years’ experience covering local, state and federal government, professional practice and private enterprise. Meet our Executive Team.

Depth and Coverage

O’Connor Marsden & Associates was established in 2009 by former ‘Big Four’ partners and a core team of national based internal audit and probity practitioners. The business has enjoyed rapid growth and has offices in Sydney, Melbourne, Brisbane, Canberra, Adelaide and Tasmania serving an established premium client portfolio. In 2010 OCM expanded its service offerings to include a dedicated Workplace Conduct & Investigation practice to provide our clients with access to independent specialist advice.
