Will One Nation's orange wave crash over the coastal seat of Secret Harbour? | 7.30

Could the Secret Harbour by-election become the next test of One Nation's electoral strength in Western Australia? The resignation of a long-serving Labor MP has triggered a by-election in Perth's southern suburbs, creating a contest that could provide an early measure of support for Pauline Hanson's One Nation. The One Nation candidate, Luke Herdegen, is an east coast transplant — a former gym owner who has admitted to past cocaine use and who doesn't mind an ocean swim in stormy waters. Reporter Courtney Bembridge speaks to voters and candidates on the campaign trail to examine what the result could mean for Labor and One Nation ahead of future elections. 7.30 is the ABC's flagship current affairs program, delivering original journalism, exclusive investigations, in-depth analysis and interviews on the major issues affecting Australia and the world.
