Amir could not believe it when Mick told their volunteer group that in Australia, over 200 species of marine animals are impacted by marine debris, either by ingestion or entanglement. He told them that our actions affect our environment.

Amir and his friends decided that they would approach their school principal to discuss ways they could raise awareness of this topic within their school community. While most people would know not to throw things down our drain, reminders are always helpful and perhaps they can encourage more families to volunteer their time with the local Coastcare group on Sunday mornings.


Eighty-five percent of Australians live within 50km of the coast. This activity looks at the waste that washes downstream in our catchments, the impacts it has on our estuaries, wetlands and coastal areas where the rivers meets the sea.

This learning activity is the final part of a sequence of 5 individual learning activities focused on catchment management. The order of these learning activities are: the story of a river, water sustainability, what’s in a drop?, the drain is just for rain and where the river meets the sea.


For students to:

  • understand the different journey water takes through a catchment
  • learn how waste can enter the waterways
  • discover the impacts of waste on estuaries, wetlands and the coastal habitats
  • appreciate that what happens on land can impact our rivers and oceans.

This activity can be undertaken at any time of year.

Did you know?

Wetlands slow down the movement of water so material and sediment dissolved in the water settles out in the wetland.

Did you know?

Water is a universal solvent and is able to dissolve a large number of different chemical compounds. This enables water to carry dissolved solids in runoff.

Did you know?

Detergent in our waterways can make it easier for aquatic life to absorb any pollution in the water.

Did you know?

In Australia 90% of the population lives in less than 1% of the country’s land area, and 85% are living within 50km of the coast.
