Really? Those were hundreds of meters high? Are you sure? It’s hard to believe. It seems like geologists often come up with these wildly speculative ideas, almost like children imagining things. A rough estimate suggests that about 10-15% of Australia could remain above water if the sea level rose by 200 meters. The land above this elevation is primarily in the east and southeast, where the Great Dividing Range and other mountain ranges are located. However, exact percentages would depend on local topography and elevation details across the continent. But here's the thing: while you're imagining history and assuming your consensus is unchallenged (as usual), the inconsistencies within geology are glaring. I've lost count of the times I've encountered completely different views from geologists. It’s rather baffling when so many of your peers can't agree on basic facts. Take, for example, a group of researchers who took a well-known 10-year-old volcanic sample and sent it to multiple labs for age analysis. The results ranged from 10,000 years to 1 million, to even billions of years. Yes, science evolves, and I understand that technology and methods improve over time. But that’s not what’s happening here. Geology, in general, is not a delusion, but the constant guessing and later presenting these guesses as absolute fact is something that’s hard to stomach. So, how do you reconcile the fact that your field continuously produces vastly different numbers and conclusions? How can we trust these references when, with just a bit of digging, I could find a dozen geologists who hold completely opposing views on the same subject? Look dont get me wrong i enjoy your videos and have nothing against you personally, but I wanted to give you my honest feelings including my sarcasm and disdain about 'KZbin Geology' and from discussions with others, although more polite many people agree and are frustrated by the vast variations and continual lack of consensus. So would you care to respond to help us see your viewpoint.

This is a very good educational video. Its clarity of explanation for a non-geologist like me is outstanding. The graphic images demonstrating the changes in the reef and its development are in a class of their own. Many thanks

[@unoriginalsyn]

I've learned a lot from him ❤ love this channel

[@graemeverryt618]

365m, 385m, and woteva million years just because he really does sound educational....

[@unoriginalsyn]

@@graemeverryt618 bet you get invited to a lot of parties 🙄

[@robmadaffari6270]

One of your best presentations yet, great work.

[@mishham6388]

I agree. Great for us leypeople to wrap our heads around these things. I feel like I've learnt more on KZbin from videos such as these than I ever did at school

[@shaneconway5919]

Thank you, great subject and great to understand WA's geology past.

[@fredricktalbot1945]

I love the use of the tape measure in a chronographical sense.

[@yt.personal.identification]

Same. It was a neat way to add a wider perspective in a single image.

[@darrellturner560]

A brilliant video. Thanks!

[@tantraman93]

Thanks!

[@OzGeologyOfficial]

Thanks for the donation mate! I appreciate it 😁

[@rosa9079]

I love learning about our country. Thanks for your videos.

[@allon33]

You can see this Reef as you drive along the highway from Broome to Halls Creek.

[@rictechow231]

Great video. Whilst easterners don't know much about our geology other than gold we know nothing about westralia. Would love to have more; particularly on Vaalbara

[@unoriginalsyn]

Yet another fascinating video ❤ and now my afternoon is going to be looking at Google maps instead of working 😂

[@karamia1392]

On my bucket list. The gogo fish is a game-changer!! ❤

[@BradGryphonn]

The Mt Etna range, just North of Rockhampton is a karst formation, formerly a coral reef.

[@Ful-OGold]

Cheers for that.

[@robert-wr6md]

excellent thanks.

@ 6:02 fossilized examples of these microbialites (local name GoGo nodules) are relatively common in some locations near the Devonian reef structures. I lived in this area of the Kimberly’s for 18 months.

How's that River Valley in the beginning sliced straight through the rock 100m down ?

[@whoeveriam0iam14222]

The river was just flowing normally while the land started to go up. It went up slowly enough that the river could erode its path. Where the river didn't flow became a mountain with a gorge for the river

[@kcc879]

Fantastic! Can you do one on the Blue Mts or more specifically the Three Sisters?

[@kevin-e5h5t]

The Great Barrier Reef in Queensland currently sits in shallow water, and is only about 12,000 years old. It sits on a wide shelf, that 12,000 years ago (the early Holocene), was high and dry, because the oceans were lower back then.

[@bobtheboozer15]

The Mueller ranges mimbi caves in WA further inland I visited must have a similar story 350 million years old

[@stephenanderle5422]

Global sea level rise? Well yes probably some what. But Australia being at the equator would make a lot of local sea level rise on it's own.

[@knowname7289]

1:04 So sea level are technically "low level " now comparatively ?

[@willjones2954]

🇦🇺🇦🇺🇦🇺👍👍👍

[@nancydelu4061]

I hear "calcium" this, "calcium" that, "calcium" the other. ¿A calcium sink? It's a puzzle. Please tell us more.

[@jimmy_flaps]

Que?

[@RandyTerrell7174]

Not first

[@YRLCarlos]

first

[@joshs470]

If only we had Greta Icebergs back then we could've saved this reef! 😁

[@autisticsimon12]

Why do you call it "A GREAT BARRIER REEF" that's just a childish generalization.
