CSIRO iPhD Opportunity: Understanding gene flow and resistance in an emerging cotton pest in Northern Australia
Charles Darwin University (CDU) and CSIRO are partnering to offer an exciting PhD opportunity focused on population genetics and Bt resistance in the emerging cotton pest Spodoptera litura. The successful candidate will commence in 2026.
Scholarship and financial support:
- $41,190* ($34,190 + $7000 top-up) per annum tax-exempt stipend, indexed annually
- 3 to 3.5 years duration
- Open to Australian citizens/residents or New Zealand citizens for domestic enrolment
- Includes a generous research budget
- University relocation allowance of up to $2,000 may be available
About the project:
Cotton production in Northern Australia is expanding rapidly, but the region differs markedly from the southern cotton production areas, particularly in climate, cropping systems, and pest management practices. These differences likely shape the biology, movement, and resistance profile of key insect pests, yet there is very limited empirical data to validate this. Understanding the risks posed by northern production systems is essential to ensuring that the Resistance Management Plan (RMP) continues to minimise the evolution of Bt resistance in cotton pest species across Australia. A major knowledge gap relates to Spodoptera spp., particularly S. litura, an emerging pest in northern landscapes. Little is known about its life history in Australian cotton systems, patterns of dispersal and gene flow, current and potential pesticide resistance or role in broader landscape-level dynamics. This PhD project will provide the first comprehensive assessment of S. litura population structure, movement, and resistance development across Northern Australian cotton landscapes.
The research will form the foundation for future modelling and management strategies, helping industry anticipate and mitigate emerging pest risks. This is an excellent opportunity to work at the interface of molecular ecology, agricultural biosecurity, and sustainable pest management, with strong support from both CDU, CSIRO, CRDC and industry.

CSIRO iPhD Opportunity: The goldlined rabbitfish S.lineatus; farming down the food chain for resilient, low trophic, Indigenous aquaculture
The Research Institute for Northern Agriculture (RINA) is seeking applicants for a unique opportunity to work with an in Indigenous enterprise in a remote Indigenous community which is developing a blue economy to safeguard the future of one of Australia’s largest islands. The project will develop production methods for a herbivorous marine fish – the goldlined rabbitfish - to enable a more sustainable and climate-resilient future for Australian finfish aquaculture. The enhanced capacity of a strong collaboration between Charles Darwin University, Groote Aqua Aboriginal Corporation and the CSIRO, working alongside Anindilyakwa Traditional Owners, will yield a better understanding of goldlined rabbitfish propagation techniques and nutritional requirements. This will ultimately improve Groote Aqua’s production efficiencies and consequently improve food security, revenues and employment prospects on Groote Eylandt, which are key milestones for the Aboriginal Corporation to prepare for and facilitate the transition from six-decades of mining to self-sufficiency.
Scholarship and financial support:
- A tax-exempt stipend commencing at $48,000 per year for four years, with annual increases over the four-year period (available to Australian citizens or permanent residents, and New Zealand citizens only)
- University relocation allowance may be available
- Generous project expense and development package of $13,000/year
About the project:
Australian finfish aquaculture involves carnivorous fishes that require a wild-caught fish component in their diet. Wild fishery landings plateaued three decades ago and thus the increasing demand for and use of wild-sourced ingredients for farming fish is unsustainable, particularly with respect to food security.
Rabbitfishes are marine herbivores, with some showing promising aquaculture potential. One of the largest rabbitfish species is the goldlined rabbitfish (GLR) Siganus lineatus, a popular fish in the South Pacific, which combines flexible nutritional requirements, high tolerance to variable water quality, and strong grazing capacity for fouling control in ponds, sea cages, and tanks, while also being an excellent food fish. Groote Aqua Aboriginal Corporation (GAAC) is investigating the potential of including this species within its integrated low trophic aquaculture program to improve local food security and to develop a blue economy for a sustainable post mining future.
Over the past year, GAAC has established and maintained broodstock (monthly spawns) and conducted multiple successful larval rearing trials of GLR. This has enabled production of hatchery-bred juveniles, which have already been deployed in several trials. At the production facility, GLR were stocked into tanks deliberately allowed to develop significant macroalgal growth and successfully reduced algal biomass through active grazing, effectively “cleaning” the tanks. More recently, juvenile GLR were also supplied to the Darwin Waterfront to assist with macroalgae control. While this initiative is still in its early stages, the fish are grazing actively and showing good growth performance to date.
In this project, GAAC will work with CDU, the CSIRO and the successful candidate to develop and optimise hatchery and nursery production protocols for GLR so they can be introduced to sea cucumber production ponds to control macroalgae growth. In addition to being a ‘cleaner fish’, GLR also has great table fish potential as sustainable white flesh fish that does not require wild-caught fish in its diet. The benefits of growing this fish are therefore twofold: 1) reduced labour cost of cleaning ponds/tanks and 2) additional healthy protein produced locally. As per the Darwin Waterfront, GLR could also provide a solution beyond Groote Eylandt, such as for enclosed marinas and marine fish farms dealing with macroalgae outbreaks that are costly to remove. The project aims at enabling the assessment of the potential of GLR to play a key role for an Aboriginal community in their economic, environmental and social transition from a mining era to a blue future.

Pathways to nature-based enterprise: Enhancing biodiversity protection and livelihoods in Northern Australian rangelands
The Research Institute for Northern Agriculture (RINA) is seeking applicants for an exciting PhD project that will investigate practical ways northern beef producers can protect biodiversity on their properties and engage with nature-based markets such as the Nature Repair Market. This project is an exciting opportunity to inform practice change on-property and help producers to make more informed decisions around protecting biodiversity.
Scholarship and financial support:
- A tax-exempt stipend of $44,190 per year (comprising $34,190 RTP base + $10,000 top-up) is available for three years.
- This opportunity is open to Australian citizens, permanent residents, and New Zealand citizens (domestic students).
- A relocation allowance of up to $2,000 is also available.
About the project:
The Australian Parliament passed the Nature Repair Act in 2024, opening the newest of a number of nature-based markets where landholders can potentially gain economic benefit for protecting biodiversity and other aspects of natural capital on their property. The rangelands make up over 80% of the Australian land area, and harbour important natural values, including biodiversity. In the northern rangelands, biodiversity values are particularly significant, and many producers are keen to continue to take advantage of nature-based economies to help protect them. However, it is not clear in the northern rangelands as to what management strategies would make the most impact in terms of biodiversity or where these strategies should/could take place.
This project is a collaboration between CDU and CSIRO and the pastoral industry and focuses on rangelands of the Northern Territory and northern Western Australia. The PhD student will be supervised by an interdisciplinary team of agricultural scientists, economists and ecologists, giving exposure to the networks, knowledge and resources of both organisations. The PhD will use information about the impacts of cattle production on threatened species to identify strategies (e.g., exclusion fencing, waterpoint management, etc.) that are most effective at protecting and enhancing natural values, including biodiversity. The student will also conduct economic analyses to understand the cost and potential return from nature-based markets and any other economic benefits (e.g., increase in productivity).
About you:
- You have a research background (Honours or Masters) in environmental science, conservation biology, agricultural science, or economics, or similar, and bring a high level of academic merit consistent with RTP stipend scholarship requirements
- Hold an Australian driving license or the capacity to obtain one
- Would ideally be based or willing to relocate to Darwin, other locations possible by negotiation
Benefits to you:
- Receive a generous stipend and support for project costs

Elucidating diet composition to improve greenhouse gas emission estimates for cattle in the northern Australia rangelands
About the project:
Native pastures of northern Australia are botanically diverse, supporting hundreds of species of grasses, forbs, trees and shrubs. Species have different nutritive value, digestibility and some have anti-methanogenic properties. Current carrying capacity methodology assumes cattle eat only the herbaceous layer of vegetation including grasses and forbs, but in many environments, such as in Central Australia and the Victoria River District, trees and shrubs are known to contribute a significant component of the diet through browse. However, which species they are eating and under what conditions is not well known. Current methods used to assess non-grass dietary components are of limited use in detecting browse in northern Australia. This PhD is part of a larger Zero Net Emissions Agriculture CRC project -Low Methane Feedbase Program- which aims to quantify the anti-methanogenic properties of northern Australian vegetation, but this information will be of limited applicability without knowing how these species currently contribute to cattle diets across northern Australia. Greenhouse gas emission estimates cannot be truly representative for the system without this.
This PhD will use field collected data, including faecal environmental DNA, to understand the contribution of different plant species in the diets of cattle in northern Australia. The student will then use these data along with anti-methanogenic compound concentrations and nutritional value data to test current greenhouse gas estimates for Australia’s north. This PhD is an excellent opportunity to work closely with government and industry partners including researchers from the Northern Territory Department of Agriculture and Fisheries.
The student will ideally be based in Darwin or Alice Springs.
Project benefits:
- $44,190 per year stipend ($34, 190 RTP stipend + $10k top up)
- Relocation allowance ($2k)

Evaluating the Use of Passive eDNA Methods to Detect Saltwater Crocodiles
There have been rapid advances in environmental DNA (eDNA) research, which allows the detection of species from traces of DNA from environmental samples.
In collaboration with the Northern Territory Government, we are investigating the effectiveness of using eDNA analysis to detect saltwater crocodiles in comparison with current management methods. Sampling and filtration methods will be especially important, and this project will compare passive methods with active manual filtration of water samples. The project will combine field and lab work. Previous lab and molecular experience are highly desirable.
Project aims:
- Compare active and passive filtration methods in the detection of crocodiles
- Assess the effect of time on passive filtration in the detection of crocodiles
- Compare the effectiveness of passive filtration methods in the detection of crocodiles at captive and field sites
Tracking Antimicrobial Resistance Along a Fresh→Estuary→Marine Gradient Using Environmental DNA
Antimicrobial resistance (AMR) is a major emerging environmental and public health concern. Recent surveys have detected AMR in Darwin’s marine creeks, suggesting that effluent and urban runoff may disseminate resistance determinants into coastal systems. Rapid Creek provides an ideal natural laboratory for tracing AMR sources and transport pathways because it spans a freshwater headwater, urban stormwater network, and tidal estuary before discharging to the sea. This project will extend previous work by mapping AMR abundance along this full gradient to quantify the abundance of AMR marker genes along the Rapid Creek continuum, from freshwater headwaters to the marine mouth. Previous lab and molecular experience are highly desirable.
Project aims:
- Map how AMR genes intI1 and cintI1 change from freshwater headwaters through the tidal estuary to the marine mouth.
- Identify potential sources (stormwater, wastewater, sediments) and transport pathways (freshwater flow, tidal mixing, resuspension).
- Examine how environmental parameters (salinity, turbidity, pH, temperature) influence gene distribution.
Detecting Mertens’ Water Monitor with eDNA: A Rapid Conservation Survey for Top End Waterways
Mertens’ water monitor (Varanusmertensi) is an aquatic varanid of northern Australia that uses creeks, billabongs, and spring-fed pools. Populations have declined in some areas (e.g., cane-toad impacts, habitat change). The project will develop and validate a species-specific eDNA qPCR assay to confirm detectability at known sites and to map occurrence with a focus on Litchfield NP. Previous lab and molecular experience are highly desirable.
Project aims:
- Design and validate a short-amplicon qPCR assay specific to V. mertensi.
- Field-validate at 4–6 known-presence waterbodies (e.g., Litchfield NP pools/creeks) + 2 known-absence/low-likelihood sites.
