Info of sight: Sydney domestic Airport

Today is the day I have to go back Japan...（Ｔ＿Ｔ）

I moved to Sydney domestic Airport from Ayers Rock at first.
Then I should transfer the Airplane to go to NARTA.

But... I had a time 6 hours till board time, so I decided to
hung around Sydney city, but I didn't have so many time,
If I lost my way, I will miss my Airplane, so...

I decided to go "Opera House" comparatively near by Airport.
