The Goyder Line marks the line of reliable rainfall in South Australia. The Brisbane Line marks the apocryphal plan to abandon northern Australia during the second world war. The Barnaby Line, then, could mark the boundary of Barnaby Joyce’s appeal to rural voters.
It has long been assumed that Joyce is a Coalition plus in the regions and a minus in the cities, but his regional appeal may be changing in the southern states. If it is, that would mirror the challenges of all major parties, trying to straddle the divide between what voters want in the north compared with the desires in the south-east.
