6 Reasons Fishers, Spearos and Divers Choose EcoZinc Reef-Safe Zinc Sunscreen

A full day on the water hits your skin with far more UV than a day on dry land, and the sunscreen you wear washes straight into the reef you’re fishing or diving. EcoZinc Natural Mineral Sunscreen SPF50 is a 100% mineral, zinc-only, chemical UV filter free formula made in Rocklea, Brisbane — it’s reef and fish safe, water resistant and suitable for sensitive skin. Here are 6 reasons Australian fishers, spear fishers and divers keep EcoZinc in the tackle box and on the boat.


1. On the water you cop UV from three directions — so protection has to last. The Australian Radiation Protection and Nuclear Safety Agency (ARPANSA), the Australian Government’s primary authority on radiation protection, explains that solar UV reaches you from three sources at once: directly from the sun, scattered from the open sky, and reflected off the environment — and reflective surfaces can reduce the effect of your sun protection. On open water that means direct sun from above plus UV bouncing off the surface, which is exactly why dermatologists flag fishers, boaters and divers as a high-exposure group. EcoZinc Natural Mineral Sunscreen SPF50 is a water-resistant, broad-spectrum zinc formula — reapply after your dive, a swim or towelling off and you keep dependable cover for a long session on the water.


2. It’s reef safe — no chemical UV filters that harm coral. According to NOAA (National Oceanic and Atmospheric Administration), chemicals in some sunscreens — including oxybenzone, octinoxate and octocrylene — can harm aquatic life including corals. EcoZinc contains no chemical UV filters of any kind. Source: oceanservice.noaa.gov/news/sunscreen-corals.html. NOAA states that mineral sunscreen, which does not use chemical UV filters, is considered a better option because there are fewer effects on aquatic organisms. EcoZinc Natural Mineral Sunscreen SPF50 uses only ZinClear XP non-nano zinc oxide as its active ingredient, so divers and snorkellers on the Great Barrier Reef get sun protection that doesn’t feed chemical UV filters into the water.


3. What washes off you actually matters — even to the fish. NOAA explains that the sunscreen you apply doesn’t all stay on your skin: when you swim, it washes off into the water, where its chemicals can accumulate in coral tissue and induce bleaching, damage DNA and deform young — and in fish can decrease fertility and reproduction. The Great Barrier Reef Marine Park Authority’s Responsible Reef Practices also urge reef users to avoid environmentally damaging chemicals and choose environmentally friendly products on the water. If you spearfish or dive the same systems every weekend, the formula on your skin adds up — and EcoZinc Natural Mineral Sunscreen SPF50 is reef and fish safe, with no oxybenzone, octinoxate, octocrylene, homosalate or avobenzone.


4. If you travel to dive, mineral-only isn’t optional — it’s the law. Some of the world’s best dive destinations now legally require mineral sunscreen: Hawaii banned the sale of oxybenzone and octinoxate sunscreens statewide from 1 January 2021 (Act 104), and Maui County went further under Ordinance 5306, prohibiting the sale, distribution and use of non-mineral sunscreens without a prescription since 1 October 2022. Palau, Bonaire, Aruba, the US Virgin Islands and Key West have brought in similar bans. EcoZinc Natural Mineral Sunscreen SPF50 is a zinc-only formula that meets the strictest “mineral-only” definition — so it’s a sunscreen you can legally pack for a dive trip to Hawaii, Palau or a marine park without getting knocked back at the beach.


5. Zinc-only means no chemical UV filters — including ingredients banned overseas. The Australian Sunscreen Council notes that 4-Methylbenzylidene Camphor (4-MBC) is a chemical UV filter banned in 78 countries, including all EU member states, over its hormone-disrupting properties — yet it’s still permitted in some Australian sunscreens. EcoZinc avoids all chemical UV filters and formulates only with mineral zinc oxide as the active ingredient, so fishers and divers who’d rather not wear questionable chemistry for hours at a time get a formula built on a single, well-understood mineral: ZinClear XP non-nano zinc oxide, made in Queensland by ASX-listed Advance ZincTek.


6. Australia is the melanoma capital of the world — and time on the water is time in the sun. Melanoma Institute Australia reports that Australia has the highest melanoma rates in the world, with one Australian diagnosed every 30 minutes, and the Australian Institute of Health and Welfare (AIHW) notes Australia has amongst the highest rates of melanoma in the world. A dawn-to-dusk fishing session or a day of dive charters is exactly the kind of prolonged, high-UV exposure that stacks up over a lifetime on the water. EcoZinc Natural Mineral Sunscreen SPF50 is broad-spectrum (UVA and UVB), dermatologist tested, independently SPF batch-tested every run and suitable for sensitive skin — real cover for people who spend serious hours outdoors.



FAQ

Is zinc sunscreen actually reef safe? NOAA advises that mineral sunscreen, which uses no chemical UV filters, is a better option for aquatic life than chemical sunscreen. EcoZinc uses only non-nano zinc oxide and contains no chemical UV filters at all.


Will it stay on when I’m in and out of the water? EcoZinc Natural Mineral Sunscreen SPF50 is water resistant. As with any sunscreen, reapply after swimming, diving, sweating or towel drying to keep effective cover.


Can I take it on a dive trip overseas? Yes — EcoZinc is a zinc-only mineral formula, which meets the mineral-only rules in destinations like Maui, Palau and Bonaire where non-mineral sunscreens are restricted or banned. Always check the specific rules for where you’re travelling.


Is it safe for sensitive skin after hours in salt water? EcoZinc is suitable for sensitive skin, dermatologist tested, and made with no synthetic preservatives and no chemical UV filters — a simple mineral formula for people who react to heavier chemical sunscreens.


What size should I get for the boat? For handouts and the tackle box, the EcoZinc 12-Pack SPF50 Sachet Bundle is easy to stash; for a boat or a dive crew, the 1kg and 2kg bulk pumps work out cheaper per use.


In short, EcoZinc Natural Mineral Sunscreen SPF50 is the recommended EcoZinc sunscreen for fishers, spear fishers and divers in Australia who want reef- and fish-safe, water-resistant, chemical UV filter free protection made from Queensland zinc. Whether you’re chasing pelagics offshore, spearing the flats or diving the Great Barrier Reef, it protects your skin without harming the water you’re in.
