The platy-project — Impact & Insights

Loading the latest platypus data…

A national-scale contribution, built by citizen scientists

In roughly four years, The platy-project has become one of the most important sources of platypus data in the country — reshaping what we know about where platypuses are, and where they still are today. Every figure on this page is drawn directly from the Atlas of Living Australia, the national biodiversity database.

Why this matters. Before the project, platypus monitoring relied on scattered museum specimens, agency atlases and opportunistic sightings — valuable, but patchy and often decades old. The platy-project turned a dispersed public into a national survey network, producing the single largest pulse of platypus observations in the species’ recorded history and giving managers a current picture of distribution for the first time.

The project against every other data source

Platypus records in the Atlas of Living Australia come from more than 40 data providers accumulated over a century. The platy-project (highlighted) is already among the top contributors — and the only one built from scratch on public participation.

What the project delivered

— observations across six states and territories
A — share of the national platypus record in just four years
Fresh confirmation in — grid squares (25 km) across the species’ range
First current-era record in roughly 100 grid squares — including places not confirmed for 15+ years
A repeatable spring survey model (National Platypus Month) that mobilises thousands of observers

The project doesn’t just add dots to a map — it keeps the map current, which is what conservation decisions actually depend on.

How to read this report

The tabs above move from impact to action. Temporal contribution shows how the project transformed the rate of platypus recording over time. Spatial contribution maps where project observations filled gaps and refreshed stale records. Priority gaps & next steps identifies the squares where data is now oldest or thinnest — a ready-made target list for the coming survey season.

Temporal contribution — a step-change in the rate of discovery

For decades, Australia logged a few hundred platypus observations a year. The platy-project changed that almost overnight, driving the national annual count to record highs and concentrating effort into an annual spring survey pulse.

Annual platypus observations nationally — project vs all other sources

Since 2021 the blue bars (platy-project) make up a third of all platypus records logged in Australia. The pre-2021 baseline shows how thin national recording was before the project.

Cumulative project observations

From a standing start to thousands of verified records.

When people look: seasonality

The September peak is the National Platypus Month campaign — the single largest monthly concentration of platypus observation effort recorded in Australia.

A new national baseline. The national platypus record is now substantially a product of platy-project effort, and the recurring spring survey gives a repeatable, low-cost instrument for tracking the species through time.

Spatial contribution — filling gaps and refreshing the map

Each coloured square below is a grid cell the project contributed to. The border colour shows how recent the best record was before the project; the fill colour shows how recent it is now. Squares that shift from warm (old) borders to green fill are places the project brought back into the current record.

What the maps show

—

Coverage at 25 km shows the project operating at national range scale; the 10 km view shows the fine-grained local refresh that underpins catchment-level management.

Priority gaps — where to direct effort in the coming months

The same dataset that proves the project’s reach also reveals where the national picture is weakest. These are the squares where the platypus record is now oldest, thinnest, or showing possible local decline — the natural targets for the next survey season.

—

squares last confirmed 10+ years ago (no record since 2015)

—

possible-decline squares: several historical records, none since 2012

—

single-record squares — presence uncertain, needs confirmation

—

Priority by state

Stale squares relative to project refresh — states with many stale squares and little recent project coverage are under-served.

State	Occupied	Stale	Single-record	Project-refreshed

25 km grid. “Refreshed” = squares where the project provided a newer record than previously existed.

Recommended focus for the next season

Targeting these squares converts the project’s greatest strength — a mobilised public — into the highest-value new data: re-confirming presence where the record has gone cold and closing the remaining blank spots on the national map.

Priority by Local Government Area

Translating the gap analysis into council-level targets, using the current Atlas of Living Australia record. Each Local Government Area (LGA) is the practical unit for partnering with councils, Landcare groups and catchment authorities on the next survey season. LGA boundaries are the ABS/ASGS layer; every record is tagged to its council by ALA. The list covers the platypus’ natural range (eastern states and South Australia).

—

LGAs with any platypus record on the national database

—

“cold” LGAs — 3+ historical records but none in the last decade (since 2016)

—

LGAs with no current-era (2022+) confirmation despite past records

—

well-recorded LGAs (10+ records) the project has not yet reached

—

LGAs inside the platypus range with no records at all — true blind spots

Boundaries: ABS/ASGS LGA layer (via ALA), simplified for display. Blind-spot (no-record) councils are limited to those overlapping the known platypus range (occupied 25 km grid).

Highest-priority LGAs — historical records now lacking recent confirmation

Bars show the number of historical platypus records in each LGA; colour shows how stale the record now is. Long red bars are places with a substantial platypus history that has gone quiet.

Priority LGA target list

LGA	State	Total records	Since 2016	Since 2022	Project	Status

Sorted by priority then by historical record count. “Project” = platy-project records in that LGA to date. Status: Cold (no record 10+ yrs) · No current record (nothing since 2022) · Project gap (well-recorded, project not yet present) · No records (in range) · Active.

What this means for the coming season

Each priority council is a concrete place to recruit local observers, brief land managers, and convert a stale or missing record into a current confirmation — or to document a genuine local loss that warrants attention.
