The Australia-China relationship is again in the headlines, with reports of strains between the two countries, resulting in federal ministers who want to visit finding it hard to get visas.

China is reacting against the Australian government’s rhetoric and especially its legislation, now before parliament, to combat foreign interference in Australian politics.

Malcolm Turnbull plays down the issue but admits “there is certainly some tension”, in the wake of the move on foreign interference.

In this podcast, Charles Sturt University’s Clive Hamilton talks about his controversial book Silent Invasion, in which he alleges a high level of penetration by Chinese officialdom into Australian institutions.

On the flip side, the Australian National University’s Richard Rigby is confident Australian institutions are strong enough to head off any dangers.
