Marshall began his investment banking career in the 1991 UK recession working on UK Leveraged and Acquisition Financing for Dai-lchi Kangyo Bank (the precursor to Mizuno). During this time he worked on several steering committees of poorly structured and over geared buyouts of the 1980s as well as some of the most successful buyouts of the 1990s. During this period, he developed a taste for contrarian investment philosophies which still hold to this day.

Returning to Australia in 1994, with Bain & Company (ultimately to become Deutsche Morgan Grenfell Australia) in a time when there was almost no institutional Private Equity in Australia, he arranged Research and Development funding for Western Australian corporates. A 2 year secondment in 1997 to Asia by Deutsche Bank, ultimately became 8 years between Hong Kong and Singapore with Deutsche, Societe Generale and equity derivatives boutique Credit Agricole Lazard Financial Products (as Deputy Managing Director for Asia).

In 2004 he returned to Perth to re-establish ANZ’s Private Equity business in Western Australia overseeing numerous investments including the origination, management and exit of the management buyout of Nomad Building Solutions Ltd and the investment in ThinkSmart Limited; two of the Group’s most successful investments.

In an banking and investment career of over 20 years he has invested in, arranged or managed over USD 2 billion in investments for multi-nationals, or corporate and institutional Investors spanning UK, Singapore, Hong Kong, Taiwan, PRC, India, Korea, Philippines and Australia.

​A native of Perth, Marshall was educated at the University of Western Australia (BCom) and Cornell University (MBA).
