Jon Nester – Victorian Branch Manager

Jon Nester

My interest in science and Australia’s unique environments lead me to a career change in 2010. Building from the solid work ethic I established from many years in the construction industry I completed an Applied Science (Environmental Management) Degree at the University of Ballarat finishing in the top 15% of my peers. My high grades allowed me to undertake an internship at Castlemaine Goldfields (CGT) where I learnt the level of professionalism that is needed to succeed in my new field. I was proud to present findings from research I conducted at CGT at the 5th Biodiversity across the boarder’s conference regarding CGT’s revegetated sites. I gained full time employment with Aus Eco Solutions as an Environmental Technician, which was soon followed by a promotion to Field Coordinator. Both these positions allowed me to interact with the environment and people who are also dedicated to restoring significant areas of Australia’s biodiversity for the future. I took over as the Victorian Branch Manager of Aus Eco Solutions in October last year and am excited about adding value to the many important projects we are currently working on.

I aim to build on the success Kristian and Kerrie have had and take the company to the next level by providing our clients with a full range of professional environmental services including consulting and management.

Rachel Nelsson- Field Coordinator 

My interest in Conservation and the Australian environment was sparked when I started spending time at a Conservation estate near Wedderburn regional Victoria. As I started learning more about the Australian Environment I decided to undertake the Diploma of Conservation and land management at Federation University in 2019. Once I completed the course I started working at Aus Eco Solutions as an Environmental Technician, this role gave me the on ground experience to better understand how to manage invasive weeds and work to help restore Australia’s ecosystems.  At the end of 2021 I then become the Training coordinator for a short time before becoming a Field coordinator at the start of 2022. Since becoming a Field coordinator I have learnt a lot about supervising on ground crews and developing management plans for on ground works.

Teagan Armstrong  – Geelong Projects Coordinator 

Since childhood I have had an interest in the natural environment. This has stemmed from growing up on a farm on the Bellarine Peninsula. In 2014, I went to The Gordon TAFE to study Certificate IV in Conservation and Land Management, the following year I went on to complete a Double Diploma in Conservation and Land Management as well as a Diploma of Sustainability. Throughout my time at TAFE I had the opportunity to work with many different organisations including, Parks Victoria, Barwon Coast Committee of Management, Friends of Groups, Estuary Watch, City of Greater Geelong Council, Landcare Groups, ANGAIR (Anglesea, Aireys Inlet Society for the Protection of Flora and Fauna), Portarlington CFA as well as Conservation Volunteers Australia. Following study, I participated in two Green Army Projects, one for Parks Victoria in and around the Werribee River Park, and one for Conservation Volunteers Australia in and around the Geelong, Bannockburn area protecting the Victorian Volcanic Plains. In more recent years, I gained full-time employment at Aus Eco Solutions as an Environmental Technician, which was followed by a position as the Training Officer, and then finally as a Field Coordinator. Throughout the years (2018 – 2020) I have built up our client base in the Geelong Region, which eventually led to the opening of our Geelong Satellite Depot in 2021. I am now the Projects Coordinator for all of our clients in the Geelong Region and have been operating out of the Geelong Satellite Depot since 2021.
