Australian journalist Cheng Lei, who has been detained in China on national security charges for the past three years, has spoken publicly about the harsh conditions she has endured. In a heartfelt open letter to the people of Australia, Cheng reveals that she is only allowed to spend 10 hours a year in sunlight and hasn't seen a tree since her detention.

She reminisces about her life in Australia, recalling the beauty of the natural landscape and the kindness of strangers. Cheng's family and even the Australian ambassador to China are unaware of the specific charges against her, which are said to involve passing on state secrets.

The delay in her sentencing has led to speculation that her case is being used as a bargaining chip in Chinese government negotiations with Australia. Australian Prime Minister Anthony Albanese is facing pressure not to travel to Beijing until Cheng and another detained Australian, Yang Hengjun, are released.

In a separate statement, Cheng expresses her deep love for Australia and her longing to be reunited with her children, who are living in Australia with their grandmother. Australian Foreign Minister Penny Wong reiterates the country's support for Cheng and calls for her basic rights to be respected.
