Our Team

Hydrobiology was incorporated in 2001 by Andy Markham and Ross Smith who met in Papua New Guinea in 1991. By 2002 we had moved from home offices to a Milton, Brisbane premises where staff levels, turnover and global exporting activities expanded. In 2006 Hydrobiology established a Perth office, which reflected our geographic project spread across tropical and sub-tropical Australia. An office in Papua New Guinea closely followed in 2010. In 2018 we opened an office in Singapore to better service the Southeast Asian market.

Early company projects were a mixture of Local and State Government work in Queensland, Ports and resource projects in Papua New Guinea and Indonesia. This diversification continued over time which has resulted in an extensive client base of high profile clients with a geographical reach that exceeds most of our peers. Our company works locally near the office bases, and in distant and remote areas where our expertise is required. These services are underpinned by investment in state-of-the-art monitoring equipment and support systems, and by ensuring senior staff are heavily involved in providing client services.

Dr Andy Markham is a Fluvial Geomorphologist, Surface Water Hydrologist and Chartered Environmental Scientist. He has a PhD in fluvial geomorphology from London University, over 30 years of experience and has worked on consulting assignments worldwide.
