Andrew founded Fender Geophysics in 2008 with an objective of making it the premier geophysical service provider in Australia. He aims to deliver geophysical services at the highest industry standard.

Andrew has 30 years’ experience working in mineral exploration and construction. He has expertise in many geophysical techniques specialising in induced polarisation, resistivity, and electromagnetic methods.

Andrew has extensive skills in project management, project logistics and WHSMS. He has made safety a key part of the Fender culture. He has extensive experience leading and conducting fieldwork in remote Australia as well as the Amazon, Fiji, Russia and Peru.

Andrew is a member of the ASEG and Technical Committee member for the GGSSA. He makes sure that Fender is using industry best practice in all its activities. In 2018 he received the Lindsay Memorial award for being a credible and worthy ambassador for the discipline of geophysics.



Doug brings 33 years of field survey and management experience from varying geophysical perspectives. His career experience is international having worked in South Africa, Pakistan, India, China, the Middle East, Papua New Guinea and most of Asia.

Doug is a qualified surveyor having graduated from the University of Southern Queensland with an Associate Degree in Spatial Science. His surveying background is important in making sure that data acquisition is done in the right place.

Doug’s management experience is important for the overall running of the business and management of individual projects. Before joining Fender he spent 15 years in the Middle East managing a survey company that specialised in terrestrial, mobile, and airborne LiDAR. He also has worked as an operations manager for Fugro Oman and Geoterrex-Dighem.

Damian Hennessy BSc


Damian has over 28 years of experience managing international geophysical surveys and works frequently throughout Asia, South America, and the Pacific region. He is one of Fender’s most experienced survey managers and has managed large-scale projects using all main geophysical methods including induced polarisation, electromagnetic, magnetics and gravity.
Damian has strong project management experience and specialises in delivering large, complex IP surveys with large teams of field staff often in remote locations. He is adept at managing and scoping complex projects using the diverse expertise of the Fender team. He facilitates the development of the most effective methodologies allowing each team member to contribute from their specialty. His broad experience has given him the opportunity to mentor many Fender staff to ensure the highest standards are maintain during surveying.

Sahala has worked across Australia, Indonesia, Egypt and France from small team to large team of the geophysical crew.

He has a NSW construction white card, Senior First Aid, White Card, 4WD safety qualifications.

Sebastian Clar (Dipl. Geophysics)


Since graduating from Kiel University, Germany, in 1995 Sebastian has experienced a wide variety of geophysical techniques, ranging from basic ground magnetics for UXO detection to seismic oceanography based on multi-channel marine seismic data.

He has extensive experience with GPR, ground and airborne magnetics, resistivity, EM, IP, seismic, and down-hole geophysics. Various work assignments have led Sebastian from his native Germany to Spain, the United Kingdom, Denmark, and the Netherlands.

He relocated to New Zealand in 2005 and since then has worked on a range of geophysical projects as well as projects in Australia and New Caledonia. Sebastian enjoys project design and management, data processing and interpretation, report creation, field work and equipment maintenance.

His hands-on experience and his high commitment to safety make him a consistently valued contributor to Fender’s projects.

WORK WITH US: employment opportunities

Fender Geophysics is frequently looking for casual field staff on geophysics crews. The role offers great opportunity for travel as we undertake surveys all over Australia and have offices in Sydney and Airlie Beach in Queensland.

The majority of surveys are in NSW, Queensland and Victoria.

The survey locations can be remote. Field stints can be up to 4 weeks. Crew stay in a range of types of accommodation from tents in field camps to country pubs and motels or mine site accommodation.

Once on a survey all meals and accommodation are paid for. Travel to site is paid for though employment is usually ex the location of employment being Sydney or Airlie Beach preferably.

Applicants must have a current drivers licence and be comfortable driving in Australia.

Preference is given to:
• People with an interested or educated in geoscience. Geology, geophysics, geotechnical.
• People with an engineering background.
• People with an electrical or mechanical trade.
• Practical people who like to engage with a team.

NB: Despite the remote nature of the work and that it is in the field of mining and minerals exploration it is ineligible as specified for work for your second year 417 visa.

However if you have completed the specified 88 days and looking to extend your Working Holiday Visa, this could be right up your alley.
