It's the Swan River but it may as well be called the Berlin Wall – so few are the Perth people who cross the river at weekends.
The divide between North and South of the River is so well known the sides even come with their own abbreviations, NOR and SOR. Perth residents are united in using these terms, to the confusion of outsiders.
According to the vitriolic stereotypes to be found online, those who live North of the river are 'pretentious ****s' who steal all the new trains, with one chap starting an anti-NOR Facebook group.
Meanwhile, another writer, claims SOR is 'full of scum bogans who hang around Kwinana doing burnouts in their *****y VT Commodores with… 18" inch or larger rims'.
One bemused commentator noted "the two halves of Perth were so divided that two people from the north side wanting to have an extra marital affair need only meet up south of the river and they were unlikely to be seen by anyone they knew."
The local newspapers perpetuate the great divide, splitting their real estate listings into the regions rather than alphabetically, as is common elsewhere.
