My Target is IELTS Total 8

Hi all, this may be is [1] the first article that I posted on italki.com. I have been to in Australia for 5 five [2] weeks which feels very long in my life. I would miss Sydney after I leave this country. The clouds, the ocean, the scenic views, bushwalking, the desert... I'm so lucky that I have experienced some such wonderful places. During my stay, I found that even I can live in here without any inconvenience [3] but I still know (that) my English skill in not good at all. I can read and listen but my oral {or "spoken"} English is such a mess. I still have a long way to go before I become a real Chinese-Japanese-English translator -- a professional one -- and not just write something like a primary school kid.
I want to go to The University of Queensland to study the Master of Arts in Japanese Interpreting and Translation. I know it's hard for a Chinese to study this program because both Japanese and English are not my native language [4]. It is hard and I can feel that there are some walls between these three languages in my brain. I need a hammer to break it through. I need more nutrition {better: "infusion", or "nourishment"} of English.
Once I go back to China, I would like to take an IELTS exam. I will start to memorizing IELTS words today.
Oh, I feel bad because every sentence I write is so short. Although it's enough for others to know what I'm trying to say, but maybe next time, I should will try to write some longer sentences. And one day I can write some beautiful sentences.
Byebye, I would go to Hornsby and walk {=hike?} the Blue Gums Walk tomorrow.

1. "May be" expresses doubt, and this information is factual. It *is* your first post.

2. Numbers up to ten are written out in English composition.

3. In this context, where you're talking about difficulty because of the language barrier, it's better to say "I can live here without much difficulty". "Inconvenience" has more of a physical implication. Ex: Even though I live close to a supermarket, it's inconvenient for me to walk there because it is across a busy highway.

4. Better phrasing "...because neither Japanese nor English is my native language"
