Australian police have confiscated 2.7 tons of cocaine hidden within a network of underground bunkers in Sydney. This operation represents the largest cocaine seizure in Australian history, according to the BBC. The illicit drugs were discovered during a complex investigation, details of which have not been fully released. Authorities estimate the street value of the cocaine to be approximately 500 million euros. The seizure is a significant blow to international drug trafficking operations targeting Australia. Investigations are ongoing to identify those responsible for importing and distributing the narcotics. No arrests have been publicly announced at this time, but police indicate further developments are expected.
