If the ocean is the thing you read about anyway, this is the organised version of it. The list here holds 1 course, a Certificate in Marine Studies from My Learning Online, and it runs entirely online. You start with how a marine system works, then move to reefs and shallow water, then to the animals themselves. Sharks, dolphins, whales, turtles and seabirds all get their own turn. By the end you can look at a reef or a rock pool and actually know what you're seeing.
Marine studies comes down to knowing what lives where, and why it manages to survive there. The certificate opens with the ecology of a marine system. You learn how a reef or a stretch of shallow water actually functions before you meet anything living in it. Then it works through the animals in order. Shellfish and crustaceans come first, then fish, then marine mammals. Turtles, sea snakes and seabirds follow, and they're the ones living between the water and the land. The second half sorts the ocean by group, from simple organisms and marine plants up through cnidarians, worms, arthropods, molluscs and echinoderms. Human impact and fishing get their own treatment, because you can't read a coastline honestly without them.
My Learning Online delivers the certificate online, and you set the pace yourself. Nobody schedules a class, and there's nowhere to travel to. The material arrives as video tutorials and written guides, and tutors are reachable by phone and email when something doesn't land. At the end you receive a certificate of completion and a transcript of the units you finished. This one isn't nationally recognised training, so it's worth going in clear-eyed: you're buying the knowledge, not a credential that gets checked. The fee, the access window and the payment options all come from My Learning Online once you ask, and asking commits you to nothing.
Compare what each one covers, then enquire on the one that fits you. The provider sorts out the details with you directly.
Do I need to dive or get in the water?
No. Everything is studied rather than done in the field, so the course works the same whether you live on the coast or hours from it. Plenty of people take it alongside diving or snorkelling they already do, and the reading makes more sense of both.
Is the certificate nationally recognised?
It isn't. My Learning Online issues its own certificate, and this course doesn't appear on the national register of accredited training. For learning a subject you're genuinely interested in, that distinction usually matters less than people expect. It's still better understood before you enrol than after.
Will this count toward a marine biology degree?
Not as credit. Universities set their own entry rules, and an unaccredited certificate sits outside them. What it can do is give you the vocabulary and the groundwork first, which tends to make a formal course less of a cold start.
How long does it take to finish?
As long as you choose to take, since nothing about it is timetabled. My Learning Online can tell you the access window and the expected study hours when you enquire. Most people fit it around work, a unit at a time.
Why is there only one marine studies course?
Because that's what providers had available for this subject when the list was checked, in August 2026. Marine study is a narrow field in Australian online training. If your interest sits closer to animal care or conservation, those areas carry more listings.
