Australia's far-right One Nation party has unveiled a string of contentious candidates for Victoria's upcoming state election, including a former Liberal candidate with alleged underworld connections, a naturopath who endorsed Donald Trump's disputed claim linking paracetamol to autism, and a former shire councillor convicted of drink-driving. Among the candidates is Michael Piastrino, whose campaign launch for the outer-suburban seat of Berwick was attended by individuals with criminal records, including a man convicted for involvement in an organised car-theft ring. The revelations raise questions about the party's candidate-vetting process, despite One Nation claiming to have introduced more stringent background checks and social media screening ahead of the November poll.
