The sentence you wrote is mostly correct and clear! Here's the sentence with a small improvement for clarity:
"Koalas never drink water. They get all the water they need from fresh eucalyptus leaves."
Explanation:
- I added the word "water" after drink to make it clear what koalas never drink.
- Keeping the rest of the sentence the same is perfect because it explains how koalas get water in a simple way.
Great job on writing a clear fact about koalas!
