What do you think of a working holiday?

I'm in my 3rd year of university and I'm gonna take a year off and go to Australia for a working holiday.
Working holiday is a program where I can not only earn money, <em>but learn english as well. </em>
I'm thinking that it might be a good opportunity for me that I go abroad and experience a  

bitter- sweet experience at the same time! one of my friends who had already been to Australia for a working holiday said that he had a good time at there, but he also saw many people who couldn't adjust to new surroundings and had to go back to their country. so I'm worried that I might be like one of them. I will <em>still</em> go abroad anyway.
if you're reading this and you know some infos of how it'll be like in Australia for a working holiday, please tell me.
if you're an Australian, I've got so many questions for you!

I wonder if these expressions are okay.

I remember him because his Korean name is unique.
I remember him whose Korean name is unique.
I remember him because of his unique Korean name.
His Korean name is so unique. That's why I remember him.
His Korean name is so unique to a point where I can't forget him.
The uniqueness of his Korean name has been engraved him in my brain.
He has a unique name. That's why I remember him.


The basic meaning is the same but I wrote those sentences in various ways.

How about that?
Everything is okay?

Other than some improvements, your sentences are very good! :)

Write about what happened today.

This morning I had a very pleasant dreams.

During my school days, I had a crush on a woman who I dreamt that I had lunch with.  

My roommate woke me up from the dream and I was ready to go to work .

I recently worked with the ROK and the rest of the NCOs four years.

I suddenly wanted to go on a trip.

English for the trip I felt it necessary.

I found a website where you can learn English through Google .

A lot of characters does not look like English.

This seems to help me with my English writing which is enjoyable in the morning, like a dream .

Thank you.
