This card came as an official, AU-66726. When I first saw it, I thought it must have been from China, because that's definitely Chinese written on the front of the card. The largest characters I can even read (in Japanese anyway): 南天寺 ("southern paradise temple"). However, it was definitely mailed from Australia, as you can see if you scroll down and look at the stamps.
Nan Tien Temple, located in Wollongong, New South Wales, Australia, is the largest Buddhist temple in the Southern Hemisphere, according to the back of the card. Pictured is the seven-story pagoda, constructed in Chinese architectural style. The temple complex also incorporates styles from elsewhere in Asia, including Tibetan monastic architecture in the main temple buildings and a Japanese garden surrounding the pagoda. You have to remove your shoes before entering the temple buildings.
Lady Gaga visited Nan Tien Temple on her Monsters Ball tour in March 2010.
And the stamp. This one shows Tasmania's Russell Falls.
For some reason, the postal cancellation is on the picture side of the card, not on the stamp. Weird.
