Translating Caring into Action

many things we can’t change. but many we can! 


translating caring into action isn’t done out of hope. It’s because recognised as entities with rights to exist and flourish, to be restored, regenerated and respected.

Monitoring of Hobart Rivulet platypuses

Ongoing monitoring of Hobart’s urban platypus population is central to our mission to protect and conserve. In addition to spending ~20 hours per week monitoring platypuses first hand, we also run 12 trail cameras that operate 24/7.

Behavioural data, images and video gathered through monitoring are grouped by individual animals and entered into our HRP database.

@hobartrivuletplatypus runs ongoing community engagement and awareness campaigns including:


Central to our community campaigns is the authentic sharing of the Hobart Rivulet platypus’s lives.

Empowering the next generation of nature guardians is critical.

In 2023 we began rolling out the Seize it, Snip it, Bin it! looped litter awareness campaign.

Seize it, Snip it, Bin it! encourages kids to take responsibility for their own rubbish, and action around the problem of looped litter.

In the second half of 2023 we ran sessions in 20 schools, located in Tasmania, mainland Australia and the United States.

With over 1000 hours of experience working in close proximity to platypuses, we have developed techniques to:

  • locate and identify platypuses
  • confirm entanglement prior to capture
  • capture & assess entangled platypuses
  • minimize stress & disturbance to entangled platypuses


Contact [email protected] if you suspect a platypus may be entangled in litter.

change this to emphasize a litter free hobart rivulet. Our ongoing monitoring of the Hobart Rivulet means we are often amongst the first to become aware of a pollution event.

Hobart Rivulet pollution events since 2020 include:

  • Rubbish from the the city tip and Hobart’s stormwater system entering the rivulet following heavy rain
  • Construction companies washing building materials ‘down the drain’ and into the rivulet.
  • Ongoing leaking sewer due to aging infrastructure

All pollution events are documented and reported to the City of Hobart and the EPA.

Works in the Hobart Rivulet are a contentious issue. The period of lowest rainfall when works are often planned, coincides directly with the platypus’s breeding and nesting season. We speak and act on behalf of platypus!

  • Reporting and subsequent investigation of damage to a platypus burrow during works in the Hobart Rivulet. Platypus burrows are protected by law, under Tasmania’s Nature Conservation Act.
  • Cessation of bridge works until necessary permits and environmental protection measures were put in place.


@hobartrivuletplatypus has a permit from the City of Hobart to enter the waterway to collect rubbish, including immediately after storm events.

Ensuring official information related to platypus behaviour in Tasmania is up to date is critical to the ongoing management of the Hobart Rivulet.

We regularly communicate with platypus scientists including the Australian Platypus Conservancy, and the wildlife team at DPIPWE.

Significant findings from our monitoring program are shared through discussion and research notes with the scientific and conservation community.


The City Tip is the biggest polluter of h

The Boulder Trap is the largest pond in the Hobart Rivulet. It is a popular meeting place for platypuses during the breeding season, along with providing a critical refuge in the event of bushfires.

We continue to lobby the City of Hobart to:

  • take steps that allow the Boulder Trap to run full year round
  • avoid emptying and cleaning the Boulder Trap during the platypus breeding and nesting season
  • minimize the number of days the Boulder Trap is left empty
  • install interpretative platypus signage at the Boulder Trap.

We partner with, and provide resources to, like minded organizations such as World Wildlife Fund and the Australian Conservation Foundation.

We work with local stakeholders to revegetate strategic habitat.

The story of @hobartrivuletplatypus was the basis for The Platypus Guardian documentary, released in June 2022.

We are currently working Becoming Platypus, a short form documentary set to be released into schools June 2024.

Where necessary, we engage media including:

  • Radio spots 
  • TV News
  • Newspapers & magazines


Media coverage to date includes: ABC News, Win News, Channel 7 News, ABC Radio, Australian Geographic, The Mercury, RACT, and Hobart Magazine.
