As China grows in power, there are fears that it is trying to alter the course of Australian politics. The Australian government has legislated against "foreign influence operations" after allegations of Chinese spies making payments to lawmakers.

Are these genuine concerns, or are they merely the latest expression of covert racism towards Australia’s Chinese minority? Australian reporter Heidi Pett investigates for Chinese Dreams, a 5-part series examining how China’s rise is influencing countries across the globe.
