Part of the Great Southern BioBlitz
Great Southern BioBlitz
Four days. Four adventures. One big biodiversity count.
The Great Southern BioBlitz is a spring snapshot of life across the entire southern hemisphere. Over four days, people in Australia, New Zealand, South America and southern Africa record every living thing they can find and upload it to iNaturalist — building a single, shared picture of southern biodiversity.
GSB 2026 runs Friday 27 to Monday 30 November, with a further 14 days afterwards to upload and identify everything you recorded.
Green Heroes takes that global effort underwater at Cook Island Aquatic Reserve. Fish, invertebrates, corals, algae, seabirds, turtles — if it lives here, we want it on the record. Reef sites are badly under-represented in bioblitz data, which makes what we capture here genuinely valuable.
Four days, four ways to explore
Four outings across the official BioBlitz window, Friday 27 to Monday 30 November 2026 — starting with a double header on the Friday and finishing on land across the weekend. Each one is booked separately.
Dive Cook Island
Friday 27 November 2026 · 7:00–10:00am QLD time · Fingal boat ramp
$125 per person
Go beneath the surface of Cook Island Aquatic Reserve for a dedicated scuba survey. From reef fish and rays to nudibranchs, corals and other marine life, we’ll document as much biodiversity as we can during our dive.

Snorkel & Search
Friday 27 November 2026 · 10:00am–1:00pm QLD time · Fingal boat ramp
$99 per person
We’ll head out for a guided snorkel and keep our eyes open from the moment we leave shore. Along the way, we’ll record the marine life we encounter above and below the water, photographing anything interesting for our iNaturalist projects.

Look Up!
Saturday 28 November 2026 · 7:00–9:00am QLD time · Fingal boat ramp
$50 per person
We’re taking the BioBlitz to the skies with a boat-based birdwatching expedition, beginning in the Tweed River and heading out to Cook Island Aquatic Reserve. We’ll circumnavigate the island, exploring its rarely seen coastline while searching for resident and migratory seabirds.

Land-Based BioBlitz
Sunday 29 & Monday 30 November 2026 · from 9:00am QLD time · Salt & Stone Café, Fingal Head
Free · both days
Explore your backyard, across both days. We’ll meet at Salt & Stone Café in Fingal Head, split into small groups and head out to explore the surrounding landscape. With just 45 minutes on the clock, each group will see how many different species they can discover and record.
Look closely — birds, insects, plants, fungi, reptiles and everything in between could make the list. Then we’ll return to the café to share our findings, compare observations and see just how much biodiversity we discovered together.

Every observation counts
Throughout the four days, we’ll upload photographs and observations to iNaturalist to support the Cook Island Ecology project and the Fingal Head Ecology project — helping build a living record of the biodiversity found across our local environment.
You don’t need to be a scientist or an expert. You just need to be curious.
Come for one day or join us for the whole four-day BioBlitz. Explore more. Notice more. Record more.
Four Days. One Reserve.

You don’t need to know what anything is called. Photograph it, upload it, and the iNaturalist community will help work out what you found.
