The Cessna aircraft, that was stuffed with greater than 500 kilograms (1,100 lb ) of cocaine, went down while trying to leave a remote airstrip in Papua New Guinea on July 26.Australian Federal Police said in a statement that “greed played a substantial role in the syndicate’s actions” and they “can’t rule out the burden of the cocaine had an effect on the airplanes (sic) ability to remove.”Five suspects were detained in Queensland and Victoria lately, and also have been charged with conspiring to import over 500 kilograms of cocaine and several of related crimes. They face a maximum sentence of life in prison if convicted. The pilot was arrested two weeks after, after surrendering himself to police.Authorities reported the airplane had flown into Papua New Guinea from the little town of Mareeba in Far North Queensland, flying about 3,000 ft to prevent detection by radar.The cocaine stash was finally discovered on Friday following a search of the region. Its overall value was likely to be approximately 80 million Australian dollars ($57M USD), the equivalent of approximately 500,000 road prices.”With present interstate travel restrictions in place because of COVID-19, the effort to import illegal drugs into Australia reveals how opportunistic and greedy organised crime could be,” AFP deputy commissioner Ian McCartney said in a statement.The detained men — elderly 31, 36, 31, 33, also 61 — were charged with many different crimes. The first person detained faces costs of directing actions of a criminal syndicate and money laundering of over $1m AUD. A range of resources were seized by authorities, with a estimated total value of $3.5 million AUD.The drugs bust is among the biggest in recent Australian history. In 2016, a similar-sized 500 kilogram haul of cocaine has been seized by officials in New South Wales.CNN’s Angus Watson donated reporting.
