Australian Atheists Forum

The group — also known as Holy Tantra Esoteric Buddhism — has made generous donations to local charitable causes such as Crime Stoppers, and its followers' lion and dragon dances were once a key feature of cultural events.

In years past, Wang Xin De was a common sight in the Tasmanian parliament. State Labor and Liberal premiers have appeared at events alongside the group's leader, and his promotion of Chinese culture has attracted praise from Chinese diplomats and media.

Former followers say the public perception and support for the group makes it difficult to speak about their experience in a group they describe as operating like a cult.

"There are two principles: You never have questions, and the teachings are a secret," said one former member, who asked to remain anonymous.

"Whatever he says, you listen, you put it in your mind. That's all. Don't question it."
