Building up the museum in Dinkum is one of the most satisfying long-term goals in the game. Whether you’re passionate about wildlife, fascinated by the ocean, or love uncovering relics, the museum gives you a place to showcase the island’s treasures. However, tracking down every item for the museum can be a bit of a grind, especially if you're not sure where to start.

In this guide, I’ll walk you through 25 essential Dinkum items you’ll need for your museum exhibit — from rare critters to valuable fossils. If you’re like me and enjoy optimizing your playthrough, knowing which items to prioritize can save you a ton of time (and frustration).

1. Fly

A common insect but essential for the insect display. Easily caught near town during most seasons.

2. Blue Moon Butterfly

One of the more visually striking butterflies that’s available during specific months in the summer.

3. Scarlet Jezebel Butterfly

This one prefers forested areas, especially around flowers.

4. Funnel-Web Spider

A little creepy but necessary. Look near grassy areas at night.

5. Hercules Moth

Harder to find than most butterflies but worth it for your collection.

6. Barkoo Grunter

A freshwater fish you can typically spot in rivers.

7. Travalla

This fish tends to show up in the ocean during summer.

Head towards billabongs or jungle water sources to catch this one.

9. Bluefish

A reliable ocean fish that’s common in spring and summer.

10. Flounder

Find this in the deeper parts of the ocean floor.

11. Coral

Simple but mandatory. Gather coral while diving in shallow ocean biomes.

Scan the shoreline — starfish are often lying around waiting to be picked up.

Another tidepool regular that’s perfect for the marine exhibit.

This sparkling gem not only sells well but also belongs in the geology section of the museum.

20. Amber

A huge, glowing rock that’s satisfying to find and essential for display.

21. Crocodile Tooth

Sometimes dropped by crocs after a fight — it’s both a trophy and a museum item.

22. Wattle Brew Bottle

Yes, even crafted items like this contribute to the culture section.

23. Giant Clam

Found on beaches, this large clam is both decorative and museum-worthy.

24. Shark Tooth

Not the easiest to acquire, but definitely one of the cooler items for your exhibit.
