Monitoring coastal erosion in Anglesea


The Great Ocean Road coast is constantly changing.

While Victoria has a long history of weather variability such as storms, droughts and floods, climate change is projected to increase risks to coastal environments through drivers such as sea-level rise, change in wave-direction and increases in swell energy and storm tide events. These drivers affect coastal erosion, sediment supply and inundation and are expected to vary geographically across Victoria’s coastal zone.

The Victorian Coastal Monitoring Program (VCMP) aims to provide communities with information on coastal condition, change, hazards, and the expected longer-term impacts associated with climate change that will support decision making and adaptation planning.

Led by the Department of Environment, Land, Water and Planning (DELWP), the program is being implemented in partnership with community groups, university institutions, and public land managers including the Great Ocean Road Coast Committee (GORCC). This valuable research will help inform options to minimise the impacts of coastal erosion and understand the impacts of climate change on our coastal environments.

Several sites along the Victorian coast have been chosen for inclusion in the study, including GORCC managed land at Point Roadknight and Demons Bluff in Anglesea. Data collected from the mapping software will be interpreted and used to assist in the planning of future works along the coast.

To help monitor our shorelines, two members from GORCC’s conservation team are currently undertaking training with Deakin University in the use of small aerial drones.  As part of the program, GORCC will coordinate with four local citizen scientists participating in the program.

Research highlights vital hoodie sites


New research conducted by Deakin University and Birdlife Australia has found that endangered Hooded Plovers select breeding locations based on food availability.

The research compared 56 different beach sites in Victoria and collected more than 7,500 invertebrates to determine the potential food source available at each location.

Birdlife Australia’s Coast and Marine Program Manager Grainne Maguire, who co-supervised the research, said the findings were significant.

“This information will assist in the identification of potential breeding sites and help us to better understand how many Hooded Plovers should ideally exist in Victoria.

“An abundance of food was found in the vicinity of known breeding sites and these sites were largely dominated by amphipods (such as sand hoppers) whereas non-inhabited sites hosted more beetles,”

The quantity of Hooded Plover food available on beaches across Victoria varies immensely, highlighting the importance of the current known breeding sites which are limited in number.

Deakin University Senior Lecturer in Wildlife and Conservation Biology Mike Weston said Hooded Plover’s have limited breeding capacity and need help to survive.

“This research has provided insight to how much habitat is actually suitable for Hooded Plovers and the types of food sources they look for when breeding.

“There are so many people in the community engaged in the conservation effort and this research is another piece of the jigsaw,” he said.

Great Ocean Road Coat Committee (GORCC) Conservation Supervisor Georgie Beale worked tirelessly with volunteers last breeding season to protect three breeding sites on GORCC managed land.

It was estimated that the Friends of the Hooded Plover Surf Coast volunteers have donated over 1,800 hours of their time working to protect chicks.

“As a community we need to work together to conserve these known breeding sites and give the Hooded Plovers the best chance of survival.

“The research confirms that these local breeding sites are vital for the ‘Hoodies’,” Ms Beale said.

The full research paper will be published in CSIRO Marine and Freshwater Research Journal later this year.

Hooded Plovers are listed as vulnerable under the Environment Protection Biodiversity and Conservation Act 1999 and have one of the lowest survival rates of any species in the world.

Seagrass secrets uncovered


Researchers are uncovering the secrets of seagrasses in Port Phillip Bay and Victoria as part of a collaborative study into this vital part of our marine ecosystem.

The project includes researchers from Melbourne University, the University of Tasmania, the Sydney University of Technology and Deakin University and is funded by the Department of Environment, Land, Water and Planning (DEWLP).

The project aims to understand the resilience, reproductive biology and genetics of seagrass which is a primary producer – playing an important role as an ‘ecosystem engineer’.

Seagrasses recycle nutrients in the water and stabilise the marine environment helping to promote biodiversity and protect habitat.

Similar to the way in which coral reefs provide habitat in Queensland, seagrass colonies are part of vital habitat for a range of fauna species such as the King George Whiting, Australian Salmon and Pipefish.

Deakin University School of Life and Environmental Sciences Senior Lecturer, Craig Sherman said researchers were initially unsure of what the study would uncover.

“We discovered more seagrass diversity than expected in our research which helps us understand the regeneration processes in the bay.

“Diversity is essential for environmental adaptation which is why it is important for us to gain a greater insight about the processes that maintain seagrass populations.

“This research helps us understand the fluctuations in populations and how the seagrass responds to different influences,” said Mr Sherman.

Deakin University postdoctoral researcher, Tim Smith also worked on the project, examining the recovery times of seagrass in Port Phillip Bay.

“Our research showed that the Geelong arm is an important source of seagrass in Port Phillip Bay with high levels of seed production which suggests it is a ‘source site’.

“Seagrass is a really important ecosystem, so we need to understand its recovery mechanisms to ensure seagrass in Port Phillip Bay can recover from disturbances and environmental change in the future.

“It is particularly important to identify ‘source sites’ of seagrass that can enhance threatened sites so that they can be managed accordingly,” Mr Smith said.

Research reveals pest’s adaptive abilities


New research has confirmed that an invasive species is rapidly adapting to different ecosystems along the coast, allowing it to spread fast and threatening the health of the marine environment.

A team of Deakin University researchers have been studying the Northern Pacific Seastar (Asterias amurensis) in Australia to better understand its potential to expand its geographical range.

The invasive seastar species originates from Japan and is a voracious predator which has a major impact on the marine food chain, devastating marine wildlife.

Deakin University PhD student Mark Richardson has been conducting research to test whether its larvae have the ability to cope with elevated water temperatures, which may determine the seastar’s potential range.

“The experiments have established that Northern Pacific Seastar larvae from Port Phillip Bay have several genetic differences that allow them to adapt to the local environment.

“The same experiments were performed on native Japanese Northern Pacific Seastars to evaluate their genetic profiles and see whether the individuals living in Australia have developed greater tolerance to higher water temperatures.

“The results indicate the Northern Pacific Seastars in Australia have a higher ability to thrive in elevated water temperatures compared to the native Japanese individuals”, Mr Richardson said.

The heightened ability for the seastar to adapt to different water temperatures could pose a threat to the native marine wildlife along the East Coast of Australia.

The Northern Pacific Seastar spreads through ocean currents and could infest waters eastwards from Port Phillip Bay along the coast.

Project leader Dr. Craig Sherman from Deakin University’s School of Life and Environmental Sciences, said the experiments conducted on seastar larvae would improve understanding about this invasive species in Australia.

“From this research we have developed a better understanding about how seastar populations are connected and how this species is adapting and spreading along the coast.

“We are interested in the ecological impacts the seastar is having on marine communities and the rapid evolution the seastar undertakes to survive in the environment,” said Dr Sherman.

The water temperature research will be able to provide information for future marine pest management strategies in Australia.

Snapshot of the coast


A new monitoring program is set to identify what fauna species are living on our coastal reserves and measure the success of ongoing conservation works.

The Great Ocean Road Coast Committee (GORCC) is working with volunteer groups to establish a monitoring system which will gather data using a range of techniques including infrared cameras, and mammal surveys.

Flora surveying will also be conducted, with transect lines and photo points to be set up on conservation sites.

GORCC Environmental Projects Manager, Alex Sedger said that the program will provide an in-depth analysis of the different species living along the coast and help GORCC and volunteers to develop conservation strategies.

“It is important that we are able to quantify the fauna in the area to direct resources in the best strategic way.

“Our conservation has primarily focused on weed control and pest eradication, so it will be interesting to analyse what impact our work is having on the environment,” Ms Sedger said.

GORCC has engaged local consultant Luke Hynes from Beacon Ecological to assist with the revision and implementation of the organisation’s Native Vegetation and Weed Action Plan.

Mr Hynes, who recommended the implementation of a monitoring system, said the infrared cameras are an important tool in evaluating the health of the environment.

“The data collected from the cameras will provide valuable information for GORCC’s land management and will help educate volunteer groups about the animals in the area,” Mr Hynes said.

The cameras will be set up in several different locations to record both native and pest animal activity in each area.

Parks Victoria has successfully used infrared cameras in the Otways region and most recently in Wilsons Promontory to monitor fauna, capturing a number of native animals including endangered and threated species.

“The results of their research is very encouraging and we hope the monitoring we undertake in our local area will have similar results,” Ms Sedger said.

It is hoped that the cameras will also capture feral pests with a particular focus on their impact on vulnerable species such as the Hooded Plover.

Ms Sedger said the project would include collaboration with the many environmental volunteer groups working on the GORCC –managed coast.

“Volunteers are very keen to see this type of monitoring take place and we are looking forward to working with them and supporting their invaluable work,” she said.

Australia’s dirtiest beaches exposed!


Research conducted by the CSIRO has determined Australia’s dirtiest beaches.

The two year survey, which investigated over 175 beaches, revealed that Border Village, on the coast between Western Australia and South Australia was the dirtiest beach in Australia. Pearse’s Road Beach claimed the title of Victoria’s filthiest beach.

Beach detritus
Beach litter and marine debris are a serious issue. Follow some easy steps and will make a positive impact on the issue.

The CSIRO study revealed that more than 150 million pieces of litter across Australia’s coastline.

Plastics were found to be the most prominent form of litter across Australian beaches, which can have serious repercussions on marine wildlife and coastal environments.

Great Ocean Road Coast Committee Conservation (GORCC) Supervisor Georgie Beale believes this should be a reminder to keep our own local beaches pristine.

“While our coastal beaches are far better than some in terms of cleanliness, there is always room for improvement,” she said.

There are a numerous ways you can ensure the cleanliness of our beautiful beaches.

  • Dispose of waste correctly in the bins provided around the coast
  • Take your rubbish with you when leaving the beach
  • Dispose of recyclable material correctly
  • Ensure that fishing gear and supplies are not left behind on beaches
  • Report any entangled marine life
  • Join a local volunteer group on a beach clean up

“We all play a part in keeping our beaches pollution free for everyone to enjoy,” Ms Beale said.

Below is full a list of the dirtiest and cleanest beaches of each state in Australia:

  • New South Wales:
    Dirtiest: Shelly Beach, Manly
    Cleanest: Red Rock Beach, NSW North Coast
  • Northern Territory:
    Dirtiest: Cape Arnhem
    Cleanest: Cape Hay
  • Queensland:
    Dirtiest: Barney Point Beach
    Gladstone
    Cleanest: Mackay
  • South Australia:
    Dirtiest: Border Village (SA)
    Cleanest: Nora Creina
  • Tasmania:
    Dirtiest: East Kangaroo Island (West Gulch)
    Cleanest: Cape Grim
  • Victoria:
    Dirtiest: Pearse’s Road Beach
    Cleanest: Gibbs Track Beach, Lakes Entrance
  • Western Australia:
    Dirtiest: Ellensbrook Beach
    Cleanest: 80 Mile Beach

Get outside! Nature nutures health


Spending time in the natural environment results in improvements to mental, physical and social health.

Research highlights the link between the environment and our health, including a 2010 project undertaken by Deakin University, which found that psychological benefits stem from engaging with outdoor open spaces.

Get out and about on our beautiful coast! Its great for physical and mental health.

These benefits include improved mood, lower levels of anxiety, lower stress levels, lower levels of depression and increased physical activity.

Active in Parks, a Healthy Parks – Healthy People Program, is fostered by People and Parks Foundation, Barwon Medicare Local, G21 and Parks Victoria, while Medibank Community Fund is the program’s major sponsor.

Active in Parks co-ordinator Jayde Mulder said the initiative aimed to connect people to their local parks and outdoor spaces to enhance their physical and mental health.

“Parks provide a place for community connectedness, establishing social relationships and engaging in physical activity which can all have positive effects on people’s physical and mental health.

“The Active in Parks initiative provides various outdoor programs for all ages including, exercise classes, walking groups and adventure activities for kids which are all fantastic ways of staying active and engaging with your local environment.”

Coastal volunteering is another great way to experience these physical and psychological benefits.

The Great Ocean Road Coast Committee (GORCC) recognises this link and works to immerse schools and other groups in the natural coastal environment.

Coastal volunteering is a fantastic way to not only reap mental and physical health benefits, but to meet people as well.

The committee also supports and works with a variety of environmental volunteer groups.

GORCC conservation officer Georgina Beale said coastal volunteering not only benefited our environment, but our health and wellbeing as well.

“Coastal volunteering increases physical fitness and gives people a sense of belonging and pride.”

Volunteers can participate in a range of conservation tasks including weeding, revegetation, and monitoring native birds and animals. “Volunteer groups such as Friends of Taylors Park, Friends of Eastern Otway’s and Friends of Queens Park in Lorne are always looking for extra hands to help protect and enhance the environment,” Ms Beale said.

“Get involved! It’s not just good for the coast, it’s great for you, too.

“From meeting new people through to getting some exercise, there are so many reasons to get involved.”
