As I have heard before that Singapore Changi Airport is an environmental-friendly airport, so I choose it for transfer.
Hong Kong International Airport > Singapore Changi Airport > Melbourne Tullamarine Airport
1st Stop - Cactus Garden @Terminal 1
2nd Stop - Butterfly Garden @Terminal 3
As limited time, I don't go to Enchanted Garden and Orchid Garden & Koi Pond.
Then fly to My Destination - Australia!!!
