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.

When plastic (and gold wedding) rings escape into the wild

May 11, 2021

Like many places around the globe, Norfolk Island has its issues with getting rid of waste. Even so, Norfolk Island is one of the cleanest places I’ve seen (think Indonesia, Fiji, even the Gold Coast and Noosa). But residents know that we definitely can’t be complacent. The problem of rubbish disposal is an on-going one and one that is being given serious consideration by our local government. Finding the right solution is not always straightforward, easy or cheap.

In April, I took part in a clean-up of our beaches; it wasn’t perfect by any means. We picked up plenty of our own rubbish and some that had obviously drifted in on the wind and currents from elsewhere in the Pacific.

Rubbish is a huge community responsibility – it is taken seriously by residents.

Throughout the year, many locals pick up stray rubbish on their walks and swims. We have some great retail outlets here that promote a zero-plastic ethos (Prinke Eco Store in Burnt Pine is the flag-bearer on this one) and many shops don’t provide plastic bags. Some food retailers encourage customers to bring their own take-away containers. In addition, we have a dedicated group of local volunteers who stitch hundreds of boomerang bags every year for visitors and locals to use.

So, back in February 2021, it was gut-wrenching to see a couple of sand mullet, Myxus elongatus, wearing plastic collars – those rings found on plastic juice and milk bottles. Sometimes these rings escape into the wild, and this is the sad consequence. Mullet snuffle through the sand looking for food making it so easy for a ring or hair tie to flip over their noses and get stuck.


It is such a quick job to prise the collar off the bottle and snip it before putting it in your waste.


Some of the rubbish picked up by volunteers on clean-up day in April 2021

Yesterday, I saw another mullet with a ring collar, but this one looked a shiny metallic gold, with a lot less algal growth compared to the plastic ones (see righthand image). I recalled that someone had posted on our local community social media pages about a large man’s wedding ring that had gone missing in the bay earlier this year, so I decided to see if I could find the possible owner. It didn’t take long for my suspicion to be confirmed; we now have a poor mullet weighed down with someone’s (expensive) gold wedding ring.

Injecting some levity into the situation, one local wag hilariously commented, ‘Precious … maybe Peter Jackson can come over and make wun movie … LORD OF THE MULLET!’ You have to laugh!

Always trying to find the positives of any given situation, I see this as an incentive to encourage someone to relieve the poor fish of its handicap. If the ring had been boring plastic that incentive wouldn’t exist. I also see this as a great opportunity to raise awareness about this issue.

But it isn’t just about the immediate horror of seeing a fish being slowly strangled by our refuse. Earlier this week I found five golf balls in Emily Bay, all in the same vicinity, obviously deliberately driven into the bay. The following day I found another two.

A golf ball is a serious environmental hazard. As it breaks down, the core of rubber innards unravels. All 275 metres of it. This long elastic band floats, wrapping around seaweed and corals, while the outer core disintegrates into small micro-shards of plastic that are ingested by fish and plankton. Eventually, you will be eating this plastic.

And that is before you start talking about the chemicals used in the balls: zinc oxide, zinc acrylate and benzoyl peroxide are all added to the mix when the balls are manufactured. When these leach into the marine environment, and they will, they are seriously toxic to marine life.

So while seven golf balls in Emily Bay can easily be dismissed as being a minor infringement, I bet there are a whole lot more off the other coastal fringes of Norfolk Island’s golf course. I appreciate that many of these go in accidentally, but the ones in Emily Bay had to have been hit in there for ‘fun’. Why someone would do that is another question altogether, and one I can’t answer.

Like many communities, residents of Norfolk Island are doing their best, which is, I think, a lot better than most. However, we all need to remain extra vigilant. And be aware of the consequences of our actions.

Snip those plastic rings, try to keep hair ties in your hair and not let them float away, and don’t drive golf balls into beautiful Emily. She doesn’t need them.

As for the poor mullet with the gold collar. Here’s hoping we can deliver a happy ending to his story and for the owner of the wedding ring! The mullet has a life to live and it’s only fair he gets to live it.

From coral scar to aatuti farm

From coral scar to aatuti farm
June 20, 2026

Aatuti are bold little algae farmers, but how does one of their farms begin? Over the past year, I have been following several coral patches as small white scars became algal footholds, then larger defended patches. I still cannot say what caused the first wounds, but the photo sequences show something fascinating: on a reef where algae is already gaining ground, even tiny changes on the coral surface can become part of a much bigger story.

Norfolk’s water quality – when action is reported as outcome
June 15, 2026

A recent Australian Government media release presents investment, monitoring and catchment works as progress on Norfolk Island’s water quality. Some of that work is useful, and some of it was badly needed. But activity is not the same as proven improvement. This post looks at Kingston sewerage, wetlands, cattle, acid sulfate soils, groundwater and reef health, and asks whether Emily Bay and Slaughter Bay are actually being better protected.

How surgeonfishes got their name
June 14, 2026

Surgeonfish are named for the sharp little scalpels near their tails, but on Norfolk’s reef their more useful work happens at the other end. Pencil surgeonfish, bluespine unicornfish and their relatives help browse algae across the reef – a small daily job that becomes very valuable on an algae-rich lagoon reef like ours.

A shrimp storm
May 28, 2026

While setting my research cams last week, I swam into what looked like an underwater snowstorm. It appeared to be the aftermath of a mass moulting event, with large numbers of tiny, translucent shrimp-like exoskeletons drifting together near the surface.

Kingston dredging: what happens when a reef does not fit the framework
May 28, 2026

This correspondence with DCCEEW is about more than one dredging proposal. It is about what happens when an ecologically distinctive place is assessed through standard tools that do not always make its most important values easy to see. I am publishing it here because that is something we need to be aware of, both on Norfolk Island and more broadly in Australia.

Kingston dredging: the project advances, the questions remain
May 24, 2026

Kingston dredging is edging closer, and the paper trail is growing. This post brings together earlier correspondence with the Department and the latest media release so readers can see what has been asked, what has been answered, and what still remains unclear about the project, its rationale, and the protections proposed for the reef.

The lime-green coral in Slaughter Bay – a 40-year paper trail

Green Mountain – the name I give this coral in my database – is a coral I’ve photographed for years as I swim past. Then I found its backstory in the Norfolk Island National Parks archives: a rough map, reused paper, a note in the margin – ‘still thriving’. That’s how baselines begin.

What Norfolk Island’s reef tells us about environmental blind spots

The Kingston dredging proposal on Norfolk Island raises a bigger question than dredging alone: how well do standard environmental assessment tools capture the real significance of a remote and unusual reef system like Norfolk Island’s?

Hammer coral time!
March 30, 2026

Hammer corals have unique tentacles that are large, fleshy, and tubular; these terminate in a ‘T’-shaped, hammer-head or anchor. Beneath all these softly waving tentacles is an extraordinary skeleton structure, which helps define them as a large polyp stony coral.

Norfolk Island’s fishes: drifters, residents and the ones still missing
March 24, 2026

Norfolk Island’s fish fauna reflects both connection and isolation. Some species may arrive from elsewhere as drifting larvae, some populations appear to persist locally, and some fishes known from islands on either side of Norfolk have still not been recorded here. This post looks at what old survey work, regional checklists and genetic studies suggest about that more complicated picture.
