Justin's bio

Justin brings sound business acumen to the Company, along with broad commercial experience and capital raising skills.  His business interests can be found across a range of industry sectors.

He started his career as a registered stockbroker on the London Stock Exchange, typically raising capital in Europe for listed Australian companies, and later dedicated his capital market skills to assist in business development roles including a key supporting role in two successful Australian Stock Exchange listings for companies that now enjoy a combined market capitalisation in excess of $1.5bn.

This included his role as Alternate Director to the Chair of MRM Offshore (then Mermaid Marine) and as a top-twenty shareholder in his own right.  In addition to its successful ASX listing during his tenure, the company expanded its activities beyond bare boat charter operations to the establishment of a $110m multi-user supply base facility at Damper to service the offshore oil and gas activities in the North West Shelf region; now owned and operated by Toll.

Since 1998 his focus has been on the development of relatively small companies with exciting and often disruptive ambitions; including in his role as Managing Director of Harvest Water,

Justin has been a Fellow of the Australian Institute of Company Directors (FAICD) for nearly thirty years and was Chair of the not-for-profit organisation Sprout Tasmania until his recent resignation from that voluntary position.
