The Career Pathways
Plant pathologists play a crucial role in protecting horticultural crops by identifying and managing plant diseases. Their work supports biosecurity efforts, preventing the spread of harmful pathogens that could threaten Australia’s agriculture. Some specialise in research, developing new disease management methods, while others focus on diagnostics, helping growers implement effective prevention and treatment strategies. With a highly varied role that includes laboratory analysis, client communication, and fieldwork, Plant Pathologists contribute to improving crop health and protecting the industry from emerging threats.

Q&A with Ossie Wildman
Once I completed my bachelor's degree (majoring in microbiology), I then pursued an Honours degree, which focused on developing molecular diagnostics for citrus viroids.
During my Honours degree, I spent time completing research work at the Department of Primary Industries and Regional Development (NSW DPIRD) Elizabeth Macarthur Agricultural Institute (EMAI), and at the WSU Hawkesbury campus.
Once I had completed my Honours degree, a job opportunity became available at the NSW DPIRD as a Technical Officer working on a research project related to developing molecular markers for pest resistance in wheat. After some time in that role, a position became available at the NSW DPIRD working in diagnostic plant pathology, which I applied for, and have been working in this area since then. I have been working in diagnostic plant pathology for about eight years now, with over five years of this being in my current role as a Diagnostic Plant Pathologist.
We receive a wide variety of diagnostic samples. These can be submitted by government agencies, farmers, agronomists, large companies, or even home gardeners. Many samples are received for general diagnostic screening to determine whether a pathogen is causing disease in an individual plant or crop, and if so, to determine the identity of the pathogen responsible. Some samples are received from our wider NSW DPIRD team, and these may be biosecurity-related for diagnostic or surveillance purposes. We also sometimes receive samples from other laboratories for secondary confirmation. Additionally, other samples may be screened for export certification purposes, and we also conduct import screening of Solanaceae and Cucurbitaceae seed material entering Australia and undergoing mandatory screening.
The lab-based work we conduct involves a range of techniques, including observations of symptomology, plants tissue dissections, traditional microbiological culturing, microscopy, electron microscopy, molecular diagnostics, and ELISA.
The administrative side of my job includes calling and emailing clients, writing reports, and reviewing images of plants sent in with inquiries about potential pathogens. I also discuss results with clients and collaborate with colleagues from interstate government departments and the Federal Department of Agriculture, Fisheries and Forestry. It is a very diverse role, and I enjoy that aspect of it.
Because horticulture and agriculture are such broad industries with so many different roles, there is a lot of potential flexibility for lateral movement between positions.
I have worked for the NSW Government since 2013, for almost 12 years now, and they have been a fantastic employer. We work on a beautiful site, and the work we do is incredibly interesting. I feel very fortunate to be able to do it.

1. Hyperspectral imaging technology, a spectroscopic technique originally used in pharmaceuticals and petrochemicals, which is now being developed for applications in agriculture and food processing. It can be used to help assess soil health, crop and post-harvest quality, and ultimately optimise our agricultural processes.
2. Soil science and biochar, where we are developing biochar-based fertilisers for use in agricultural systems. Biochar is a carbon rich material produced through the pyrolysis of organic matter, and we are studying its benefits in improving soil fertility, reducing nutrient leaching and fertiliser use and therefore overall sustainability of our food systems.
I also have the option to work from home frequently, which provides flexibility. I live about two hours from my university office, so remote work allows me to balance research, meetings, and writing without constant travel.
Another key lesson is communication. Working in agricultural research requires engaging with people from diverse backgrounds—scientists, farmers, policymakers, and industry leaders.
Understanding different perspectives and aligning on common goals is critical to success.
