Out on A Swim

‘Out on a swim’ is a coral reef blog that tells the stories of the characters who live under the waves and what has caught my eye when ‘out on a swim’ in the lagoons of Norfolk Island. It is also a record of the difficulties Norfolk Island’s reef faces, like many others around the world, as a result of the poor water quality that has been allowed to flow onto it.

This blog is rated in the Top 20 Coral Reef Blogs in the world.

Doris – it takes a village

January 20, 2023

Transformed, Transformational

This morning marked the end of a four-month journey for Doris. From a sick, emaciated turtle with lesions across her shell, and covered with an unhealthy growth of algae, she has been transformed to glossy beautiful health. In a bittersweet moment for all of us who were there and who have been involved in her care, she was released into the waters off Blackbank, to the north of Norfolk Island, not far from Captain Cook’s monument today.

If you missed the beginning of this wonderful story, back in September 2022 Doris was plucked from Emily Bay on Norfolk Island looking sick and sad. You can read all about it in these two blog posts:

  • #operationdoris – Green Sea Turtle Rescue

  • #operationdoris – Update From Australian Marine Parks

In Greek mythology, Doris is a sea goddess who represents the fertility of the ocean – the goddess of the rich fishing grounds found where fresh water mingles with the brine. It seemed an apt name for our little turtle found, as she was, where the freshwater stream mixes with the salty waters of Emily Bay, hiding under a coral ledge, sick, weak and underweight.

Over the last four months, Doris has gone from being quietly submissive, to gradually asserting herself. Her personality quickly became evident and surprised us all; she told us in no uncertain terms what she wanted and didn’t want. Like a child, she would reject her greens, ignore us when she had had enough company, but then love having her back scratched. As she got better she became decidedly cranky, pacing back and forth in a tank that seemed to shrink around her as her personality shone. The call of the wild asserted itself. It was time.

Not only has Doris been transformed to health by a hard-working group of amazing local volunteers, but, I believe, she has proved transformational for many of us, too. The privilege of, and responsibility for, being able to care for a wild animal and to see her blossom into health is an experience many of us will never forget as long as we live.

Doris has taught us all something. She has touched our lives, educated us, informed our opinions, made us all so much more convinced that we can’t let this happen again to another turtle, to other wildlife. She has touched our lives; especially, she has talked to our schoolchildren – our future environmental custodians. Doris has alerted us to a problem in our waters like nothing and no one else could. And for that we owe her a big debt of thanks.

This morning, Hannah and Trish cradled Doris for her last journey, aboard Dave Biggs’s boat to an area of water that we considered would be a good clean habitat for her. We headed out to Blackbank, where we paused while Luca readied himself to enter the water to film this special moment. The ocean breathing gently around us as we waited – the mood quiet, sombre.

As we soaked in the moment, wildlife warrior, and our resident bird expert Margaret Christian, reminded us of a song her daughter Kath King had written some 15 years ago, presciently about a turtle at Blackbank.

‘Let’s sing it’ said Nat Grube, an islander, Doris volunteer and film crew.

And she did.

It was spontaneous, unscripted, and one of the most beautiful moments of my life.

Hannah slid Doris over the side and back into the bosom of the ocean, her home. We’ll miss her, but as she swam towards Luca, our hearts sang, too. She’s back where she should be, and hopefully she will now find her way in the world and, with luck, mature and breed, doing her little bit for the world’s endangered population of green sea turtles (Chelonia mydas).

Mission accomplished.

And maybe, just maybe, I will be lucky enough to see her one day on one of my snorkels. I hope so. My camera will be ready.

Vital statistics

We believe Doris is around 10 years old.

Her curved carapace length is 48.5cm. And she weighs about 13.5 kg, a marked increase from when she arrived into our care at just shy of 9 kg.

Special thanks

They say it takes a village:

Nigel Greenup (National Parks), Hannah Taylor, Jenny Gildert (from the Cairns Turtle Rehabilitation Centre), Trish Le Mura, Candice the vet, Jamie Donaldson, all the Parks staff, Australian Marine Parks, Natalie Grube, Luca Fox, all the volunteers (so many of you, and such special people), and Dave Biggs. And, of course, every member of the Norfolk Island community who volunteered fish, greens, ointment, water tubs, courier services – and on and on it goes.

This really was a monumental effort for a small community. Thank you.

Glimpses of recovery: what the reef could be if we let it

Glimpses of recovery: what the reef could be if we let it
Jun 13, 2025

Day 6 of this photo series from Norfolk Island coincides with the final day of the UN Ocean Conference in Nice. After a week of documenting decline, today’s post offers a different view – what reef recovery can look like when conditions improve. Drought in 2024 gave the reef a break, and the results were unmistakable: healthier corals, lower disease, and more fish. This is what’s possible if we act.

Day 5 of my blog series for the UN Ocean Conference: two long-lived coral colonies in Norfolk’s lagoon died quietly from disease. No drama – just slow collapse and overgrowth by algae. A reminder that not all reef losses are loud, but they are happening.

Day 4 of a week-long photo series from Norfolk Island, shared during the UN Ocean Conference in Nice. Today’s post spotlights a Hydnophora pilosa colony where white syndrome appeared suddenly and spread quickly, taking out around a quarter of the coral. In the months that followed, algae quietly filled the gap – a subtle but telling shift from coral to algae that’s happening across the reef.

In Day 3 of this blog post series, published while leaders gather at the UN Ocean Conference in Nice, we see Norfolk Island’s coral reef lagoon quietly delivering a stark warning: recurrent land-based pollution, coral disease, and delayed decisions are dismantling this ecosystem in real time.

Warning signs: coral growth anomalies – the slow cancers of the reef
Jun 9, 2025

Day 2’s post coinciding with the UN Ocean Conference looks at coral growth anomalies – sometimes called coral ‘cancers’. These slow-moving diseases quietly weaken coral colonies, making them far more vulnerable to storm damage and algal takeover. On Norfolk Island’s reef, I’ve watched this exact process play out over several years. This is how chronic stress silently dismantles coral ecosystems.

Today is World Ocean Day — a timely moment to launch my week-long blog series on Norfolk Island’s reef. Each day this week, I’ll be sharing photo essays that document the slow but steady pressures reshaping this fragile reef. Today: how shifting baselines make us blind to what we’ve already lost.

A personal reflection on Norfolk Island’s coral reef environment, political denial, and what John Wyndham’s The Kraken Wakes can still teach us about slow-moving disasters — and why this election matters more than ever.

Cute as buttons – Astrea curta
Feb 20, 2025

Astrea curta corals are ‘small, moderately plocoid [flattened], distinct, and almost circular’ . Normally grey-green in colour, you can see from the images here, ours are often beautiful rich gold, although they do vary. They have a neat growth habit and button-like corallites, which can grow in columns, spherically or flattened. Large colonies of these can form gorgeous undulating bumps.

From 'Watch' to 'Warning'
Jan 26, 2025

Last week, the chance of coral bleaching in Norfolk Island’s inshore lagoons was raised from ‘Watch’ to ‘Warning’ and will more than likely rise to Alert levels one and two in coming weeks. So why do I worry about water quality all the time when bleaching seems inevitable these days and so the reef is probably doomed anyway? Read on to find out.

From little things – watching them grow
Jan 4, 2025

Small numbers of different fish species is not an unusual phenomenon on Norfolk Island’s reef, but it does demonstrate what a tiny, precious, coral reef ecosystem we have, when we can count individuals on one hand and watch each of them grow, like these little blackeye thicklips, a member of the wrasse family.
