Sea week clean-up – Boat Harbour Ocean Outfall, Kurnell, NSW

Join us to collect marine debris beach and submit data on the Australian Marine Debris Initiative Database and as part of the Clean Ocean Foundation and AUSMAP

The Clean Ocean Foundation surveys ocean outfalls (see more details below), including small micro plastic sieving. This data is instrumental in building a case for better wastewater treatment and lobbying our government to phase out single-use plastics.  The data is also used for serious source reduction plans.

Pending time an numbers, the clean-up might extend to the right hand side stretch outside of the protected bay, concentrating on the high tide mark.

Kurnell beaches are also another site to consider but a long site to audit (need serious volunteers) and it will take a few hours to pace between each groin section, just like the Bate Bay stretch of beach is also a long site to audit with kilometers of high tide mark and micro plastics up the sand dune border.

Cost: Single day entry for cars is $30 per car, or $160 for 6 month season pass that ends 31/12/2019 – Free to walk.

The walk from the entrance is free, but a bit long so we can car pool – we will meet at the entrance car park and can arrange multiple lifts to beach area once we have confirmed numbers. To organise carpools before the day, please call 0414763269.

The location can also be accessed via Cape Solander or along beach from Greenhills if you are up for a hike!

Entrance is via Captain Cook Rd, then drive down the unsealed but car worthy road. Watch out for the speed humps that are very high.

Two Carparks for non-4WD cars: one near entrance is free but then involves a long dusty walk (or car pool), the other after paid entry is a dusty drive then turn left at the gate. You will see the green mesh pedestrian access gate, then walk through down through the sand path through the huts.

4WD access is all way down to the beach. Facing the ocean, turn left. We will be cleaning the small beach of the protected inlet area.

Bring water, sun protection. No toilets at this location, but public toilets at various locations nearby eg Skate Park or Kurnell.

The alternative entrance is Boat Harbour Entrance (Lindum Road): head towards Greenhills Skate Park (271 Captain Cook Dr, Kurnell NSW 2231) and turn onto Lindum Road from the roundabout. Entrance is off Lindum Road. Entry is on right.

About the Beach Plastics Survey – Clean Ocean Foundation
Plastic pollution is being found throughout oceans around the world, including our local beaches. This global issue is attracting growing concern due to its effect on marine organisms and ecosystems, and most importantly, on human health risks. Microplastics are plastic items that are smaller than 5 mm, and can have a variety of shapes such as particles or fibres. Based on their origin, they are generally divided up into primary microplastics, such as nurdles (plastic resin pellets), or secondary microplastics, such as fragments from plastic bags (film), plastic containers (hard) or fibres from textiles. There are also micro-beads which are smaller than 1mm. These tiny spheres of plastic are found in personal care products such as toothpaste and exfoliants in facial scrubs and body washes. Humans are being exposed to both plastic particles and chemical additives being released from the plastic debris of consumer society. This material is fragmenting, leaching and spreading throughout the biosphere, including indoor and outdoor air, soil, and water systems. What started as a marine environmental contamination issue is in fact very much a human health issue as well. There are many pathways for plastics to enter the marine environment, sewage ocean outfalls being one of them.

Survey on Plastic Ocean Pollution near Outfalls
The purpose of this survey is to encourage general citizen science involvement in the mapping process of plastic pollution near wastewater treatment plants along Australian coastal areas. Your participation is voluntary and all answers will be recorded as anonymous. We are asking our coastal communities to take part in a sewage-related marine debris survey with an emphasis on plastic-stemmed cotton buds. We are hoping to gather data on the prevalence and occurrence of sewage related marine debris to further strengthen our argument for upgrades to Australian ocean outfalls and protect our ocean from pollution. Your input to this survey is very much valued and appreciated.

​Plastic cotton buds on beaches have a common source, your toilet. After flushing, cotton buds in sewage go out to sea, they float and wash up on the beach or break up and can end up in the stomachs of marine animals. The Clean Ocean Foundation, together with Beach Patrol 3280, want to understand just how prevalent cotton bud marine pollution is in Australia and whether beaches found near sewage ocean outfalls are hot spots for these items.
Here is a link to the survey:
(Or if the link doesn’t work on your browser got to and select Cotton Bud Survey from the menu).
If you are unsure where outfalls are near you, please refer to the research site here:
In the AMDI database, cotton buds can be found under ‘Other Materials’, ‘Sanitary Items’. Make sure you write in the notes the number of cotton buds that you collected. A volunteer will show you the difference between confectionery sticks (lollipops) and cotton tip/bud sticks on the day.

About Clean Ocean Foundation
COF was established on the Mornington Peninsula in 2000 with a central focus on decreasing waste-water coastal outflows and increasing waste-water treatment standards and recycling volume. In 2012 after almost two decades of work COF’s campaign to obtain a clean-water outfall for Melbourne’s major sewage treatment plant was realised with the commissioning of a $420 million upgrade of Melbourne Water’s Eastern Treatment Plant (ETP) at Carrum Downs. COF was unsuccessful in attempting to stop the controversial A$3.5 billion Victorian Desalination Plant that to date has not been required although costing water-using ratepayers more than A$2 million a day to maintain. During its lifespan COF has immersed itself in dialogue with coastal communities, academic researchers, public servants and decision makers. Through these exchanges COF is convinced its perspective on water-supply issues, based on enlightened community expectations for the marine environment coupled with transparency, could drive truly sustainable water-management policies in Australia with profound benefits for the future.
