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!

Signs of bleaching – 8 December 2025

Signs of bleaching – 8 December 2025
Dec 8, 2025

I took these photographs this morning, Monday, 8 December 2025. A few warm days of settled weather, little cloud cover and low tides in the hottest part of the day have led to some early bleaching on our reef. Bleaching doesn’t always mean death for our corals, but it is concerning to have this so early in the summer season. Fingers crossed the conditions don’t last and the reef can recover.

Nature is my teacher
Dec 3, 2025

This is a thank-you note. Five years after my first Out on a swim post – written with zero marine science quals and a head full of questions – I’m still in the water, now as a PhD candidate, because an extraordinary mix of locals, volunteers, researchers and public servants decided to share what they knew. This is the story of how nature – and a very patient community – became my teachers.

Reef grief: what dredging has done to other reefs

Reef grief: what dredging has done to other reefs
Nov 30, 2025

From Miami to Fiji, from Dubai to tiny village harbours on atolls, dredging near coral reefs has left a long trail of scars – even on ‘small’ projects. This follow-up to last week’s Kingston post walks through real examples of what happened elsewhere, and what that should make us think about before we dig up our own reef.

To dredge or not to dredge? The Kingston Pier channel project
Nov 20, 2025

How much risk are we really taking with the planned dredging at Kingston Pier – and how much protection do our corals actually have on paper? This piece walks through what the federal approval does and doesn’t guarantee, explains why sediment and light matter so much to the reef, and asks the hard questions we need answered before we trade a deeper channel for a shallower future.

A coral reef out of balance
Nov 8, 2025

After the long dry spell, the lagoon was crystal clear and full of life. But with the return of the rains, something else has returned too – the brown, filamentous mats of Lyngbya. It’s not seaweed, it’s a cyanobacterium, and when it takes hold it smothers coral and rubble alike. The reef’s way of showing us that every drop of water, from tank to tide, is connected.

Aglow among the spines

Ever seen a sea urchin that seems to glow blue from the shadows? That’s Diadema savignyi showing off its reef shimmer. Beautiful, a little spiky, and definitely not to be messed with.

The funky seventies sea slug – Halgerda willeyi
Oct 15, 2025

If ever a sea slug was channeling the 1970s, it’s Halgerda willeyi. With its groovy orange lines and chocolate-brown bumps, it looks straight out of a vintage lounge suite – the kind with shag pile carpet and bold floral cushions. Proof that nature was nailing retro design long before humans caught on.

Haddon's barometer
Oct 5, 2025

This Haddon’s anemone has been quietly living in the middle of Norfolk Island’s Emily Bay for years, bleaching and recovering with the seasons. Like corals, sea anemones host microscopic algae that provide most of their food. When stressed by heat or rainfall changes, they lose colour – and tell a story about seasonal changes to the weather.

I left school in the UK nearly 50 years ago, so it was a pleasant surprise to be invited to share some images and take part in an interview for an article about my work, to be published in the annual glossy magazine the school now produces. Here is the end product.

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.
