According to a report released by Oxfam this week, the United States’ four largest pharmaceutical companies have unfairly reduced their taxes in Australia while receiving government subsidies.

Oxfam believes that these companies denied the taxman of more than $200 million each year between 2013 and 2015,  and it was entirely legal.

Jack Berkefeld spoke with Oxfam Australia Senior Economist Dr Lisa Lee and Senior Lecturer at University of Western Sydney, School of Law Dr Elfriede Sangkuhl to understand how.
