Ist mein Text so in Ordnung?

Hi! Yes, my time in Australia is great. My long list with the many things I want to do is not yet complete. Last month I was in Sydney and it was fantastic but unfortunately I was only one week there. In Melbourne I was not yet but I want to go there. Last week I've learned to surf the lessons were great and funny. I also saw a koala but only in the zoo. Furthermore, I had a barbie on the beach almost every day. I have not seen a sheep station in the outback but maybe in the holidays next month.
