I'm really excited! My dad bought a fishing boat! So, next time I go back to Port Stephens (Lemon Tree Passage, Australia) I can go fishing!
Better still, I don't need a licence to take the boat out
Even better still, the boats have barbeques! I can catch and cook my lunch-
I'm over the moon!
If you are ever in Port Stephens, Australia and you want to hire a boat for fishing, swimming or snorkelling, check-out my dad's bbq hire boat! It would make for a great holiday

What does the English idiom, I'm over the moon mean?
What does check-out mean?
What's the biggest fish you have ever caught?
Have you ever hired something? What was it?

If you are over the moon you are very very happy.
To check out something means to try/look at something in order to assess its value.
