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 page shows the most recent blog posts. For the complete catalogue, visit the ‘Out on a swim index’ page.

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

Out on a swim – reflections on wild swimming

March 5, 2023

Day 5 – March focus on Norfolk Island’s reef

On day 5 of my March focus, I thought we’d dial down what’s in our environment and instead reflect on how we use our environment for recreation and for our physical and mental wellbeing.

Swimming has been with me all my life. It provides me with three wondrous things: time, space and connection. Time to myself. Time to contemplate, reflect, explore, see and watch. An endless, fathomless space where there is no one else but my own thoughts. And a connection with our natural world – something that is so important but so often not understood as being essential to our health and wellbeing.

For me, swimming in the ocean is the pinnacle of the swimming experience. It is multi-dimensional, responding to the pull of the Moon and the rotation of the Earth. Buoyed by the motion of the waves, I am connected to our planet, to my past and my future. It represents complete freedom.

And now it provides me with the added dimensions of awe and wonder. Something that was missing from the competitive rush and routine of my earlier swimming career – standing on the starting block, following the black line.

Where I swim today is a world away from swimming as a child in England. Green mould grew on the walls of the rather shabby indoor pool with its over-heated water, communal change rooms, and the ever-present threat of some nasty infection! Dressed in rubber swim hats with frilly flowers and chin straps, and heavy, knitted regulation-navy swimsuits, it’s amazing the experience didn’t dampen what became a lifetime love!

Swimming on Norfolk Island is a privilege and a delight. I am very fortunate. And I know there are many people who feel the same way about swimming here in our beautiful coral lagoons.

Sunday is the perfect day to get out into your environment and soak it all up, whether it’s somewhere in the water like me, camping in the bush, or walking through a park. Enjoy!

Celebrating Biodiversity Month on Norfolk Island
Sep 7, 2025

September is Biodiversity Month – the perfect time to celebrate the astonishing variety of life on Norfolk Island’s reef. From new fish sightings to coral mosaics, every observation is a reminder of how much there is still to learn and protect.

Read more about why biodiversity matters, globally and right here in our lagoon.

The fate of a coral colony when it succumbs to white syndrome – four years on

The fate of a coral colony when it succumbs to white syndrome – four years on
Aug 24, 2025

I’ve tracked one plating Acropora coral from 2021 to 2025. In just a few weeks, white syndrome wiped it out. Nearly four years years on, it’s still smothered in algae and sea squirts, with only the tiniest hint of new growth. It’s a stark reminder: without tackling the root cause, we’re just watching the same sad story repeat itself.

Meet Mr Lemonhead – our lagoon’s teeny yellow boxfish with a big design legacy. He inspired a Mercedes Benz concept car, proving how nature is full of surprises. And he shares the lagoon with other critters whose tricks have also shaped real-world inventions.

Patchwork Corals: How Colonies Fuse to Form Living Mosaics
Aug 3, 2025

Some corals wear more than one colour for a reason. When Paragoniastrea australensis colonies fuse early in life, they form living mosaics. A beautiful reminder of coral cooperation on Norfolk Island’s reef.

Reef relief

Today, 28 July, is World Nature Conservation Day. After the dry 2024, Norfolk Island’s reef is looking healthier – a brief reprieve as less water - laden with nutrients - flowed into the lagoon. These photos show what’s possible. It’s a reminder that recovery is within reach – though renewed runoff could quickly undo the gains.

In Emily Bay, Norfolk Island, a single coral bommie – Paragoniastrea australensis – has stood for decades as a micro-reef, harbouring diverse marine life and local memories. Once photographed in 1988 and still thriving today, it remains a keystone of reef biodiversity and a living link between past and present.

Over five and a half years of snorkelling Norfolk’s lagoon, we’ve documented 23 fish species not previously recorded in this area. Some are local ghosts, others climate migrants. These observations help us understand and protect what makes our reef so special.

Poop power
Jun 17, 2025

Not all poop on a reef is bad poop. In fact some kinds of poop can be a reef’s most important invisible engine. Fish poop, bird poop – even poop that gets eaten again by other fish – all of it keeps the ecosystem ticking over in a way that’s nothing short of extraordinary.

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.
