Australia will review its espionage laws, the government's chief legal officer said this week, as the country seeks to strengthen spy agencies strained by juggling counter-terror work and worries about China's rising influence.

Then in December, responding to "disturbing reports about Chinese influence," the government turned its attention on interference in politics and announced a crackdown on political donations and the outlawing of foreign interference.
