Yeah this is really important. ASIO was politicised from its very beginning, spending enormous amounts of its history "investigating" the Labor Party, Australia's opposition party in the duopoly.
Look at what he said. ASIO has said almost nothing. Most of what is being reported at the moment is speculation and from anonymous sources. My reading of what ASIO actually said, this could just be a local businessman caught laundering political donations from a foreign government. Probably just business as usual except for the election cycle and recent tensions with Russia and China. In fact, one of the few things ASIO actually did say was this is nothing unusual and happening all the time.
