Do you like dolphins? Yes. Well this is for you!
Did you know that Victoria is home to a new dolphin species?
In 2011, Founding Director and Head of Research at the Marine Mammal Foundation (MMF), Dr Kate Robb, formally identified and named Tursiops australis, known commonly as ‘Burrunan dolphin’ following Australian aboriginal narrative (Charlton-Robb et al. 2011).
The Burrunan dolphin has already been listed as ‘Threatened’ under the Victorian State Flora and Fauna Guarantee Act due to its small and isolated populations. In accordance with the International Union for Conservation of Nature (IUCN) Red List and the Australian Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act), the Burrunan dolphin would be classified as ‘data deficient’.
The Burrunan dolphin is endemic to southern Australian coastal waters and is characterised by small, genetically distinct and isolated populations. There are only two known resident populations Port Phillip Bay and Gippsland Lakes.
The specific aim of this project is to investigate the population size and structure, and threatening process impacting the endangered Burrunan dolphin. With only 120 Burrunan resident to Port Phillip Bay and 65 resident to the Gippsland Lakes, the need to better understand these population, and the wider species is crucial. These population have significant conservation concern due to their low levels of genetic diversity, close proximity to urban, agricultural and residential settings and high exposure to various anthropogenic threats.
MMF’s Project Burrunan is the only research program of its kind in Victoria. With a special focus on the newly described dolphin species, this research aims to protect and conserve this charismatic and endemic dolphin for future generations to enjoy.
In order to establish greater protection and conservation for our unique Burrunan dolphin we need to bridge the gaps in our current knowledge about this new species by addressing a number of data deficiencies. Greater scientific knowledge underpinning the correct management and conservation of this species is crucial. With no data there is no incentive for action and without action we can have no conservation.
So what’s this all about?
We will be conducting an important population assessment for Port Phillip Bay and Gippsland Lakes resident population of Burrunan dolphin. Using photos of the dolphin’s dorsal fin we can individually identify and catalogue dolphins in our population. We identify individuals based on unique nicks and notches along the trailing edge of the dolphin’s dorsal fin. Each distinctly marked individual will be catalogued and used to estimate the population size, calving rates, movement patterns and identify important regions for the dolphins. This project is a crucial step to better understanding and protecting the Burrunan dolphin not only for conservation of biodiversity but also for future generations to enjoy!
The data collected as a part of Project Burrunan will go towards numerous specific projects including assessment on social alliances, acoustics and noise impact, behaviour, identifying areas of significance, robust population modelling and much more…
How can you help?
By donating to this project you are supporting ongoing research aimed at conserving and protecting our precious Burrunan dolphin. Any contribution, big or small, would be greatly appreciated and will go a long way to making this project possible.

How the funds will be used
We will be conducting seasonal surveys across both population locations in order to obtain a representative sample of the whole area. As you can imagine, travelling to different parts of the state is timely and expensive. We will be conducting 10 daily surveys each season, equating to 80 survey annually. This is the minimum number of survey days required for us to collect an adequate data set to hopefully saturate the discovery curve (identify all marked dolphins in the population over time).
Each seasonal survey cost approximately $12,000 (or $1000 per day) and is crucial to increase our knowledge on the species, investigate the population stability, the health of the populations, understand and mitigate any potential threats or threatening processes, and their risk of extinction
In a world where we hear more about the loss of species, it is amazing to have discovered a whole new one… and with your help we protect the amazing Burrunan dolphins for future generations to enjoy!
