Unfortunately we have somehow a bad reputation......
"Export' to Australia is mainly synthetic drugs and you can hide it in a letter with stamps:
"The Netherlands is a major producer, exporter and consumer of synthetic drugs, particularly amphetamines and ecstasy (MDMA). Despite the pandemic-era closure of clubs, bars and festivals, ecstasy use in the country rose. Synthetic drug production is primarily located in North Brabant and Limburg, with outlaw motorcycle gangs increasingly involved in production and trade. Criminal organizations are both formally and informally linked, and corrupt civil servants have facilitated the market. Synthetic drugs from the Netherlands are exported worldwide, with China providing a significant portion of the laboratory equipment, raw materials and chemicals necessary for their production."
Don't think that Koen is living in North Brabant and Limburg might be something with a big harbour nearby? ;-)
