swampy1
common term on the north-west coast of Tasmania for a wanna-be surfer who populates areas of beach that are not very good for surfing: The swampies are out in force today (hopeless buggers).
Editor's comments: It seems likely that this is related to the other 'swampy' (someone from Invermay). Does anyone know if this is the case?
