Leaving Australia, back to Korea

It's been more than a year staying in Australia.
I had some plan to stay in Australia for many years but things changed and plan had to be changed.

Anyway I have worked and travel during the time and have a lot of good memories.
Good friends, good places and experiences.
I think that I spent a year without any worries or anxiety.

I feel I want to stay longer and I can but it is time to find my career job.
What I did in Australia is just common casual job. It is not really helpful for the career.
(I have graduated uni 3 years ago)

Anyway,
I feel I am going to miss all of my friends and time in Australia.
I wish I could come back some time in the future.
