The 'Convoy of No Confidence' was a trucking convoy that converged on Canberra in 2011 in a failed attempt to force the Gillard Labor government to an early election. At the time, there was widespread speculation that it was an 'astroturf' or synthetic grassroots movement. This article assesses the extent to which this alleged astroturf event exhibited populist elements, measured against Taggart's definition of populism. Unlike most Australian populist movements, which have been hostile towards all major parties (or all the big banks), the convoy's participants directed their anger almost entirely towards the Gillard government. In this, they were joined by Coalition politicians and right-wing media. The article finds that such one-sidedness is insufficient to characterise the convoy definitively as an Astroturf group, and therefore not genuinely populist. It also suggests that there may be a continuum between populist and astroturf movements.
