Mr President, I ask a supplementary question. I refer the minister to the Australian Electoral Commission's figures, which show that, since 2007, the National, Liberal and Labor parties have accepted at least $4.8 million in political donations from three businessmen—Dr Chau, Mr Chun and Mr Huang—who are closely linked to the Chinese communist government. Can the minister detail the steps his government has taken to guarantee that those funds are not from corrupt activities?
