For the first time, we are part of the annual Australian “grey nomad” migration – moving from the chilly south in search of sunshine. Our van was dwarfed by huge B-double trucks on the highway. When they rushed past in the opposite direction, the backdraft pushed our extended mirrors backwards. First night was at Swan Hill on the Murray, Australia’s longest river. The Murray River provided an essential transport link to the inland in the nineteenth century, as paddle steamers carried wool south and supplies north-east. An evening riverside walk provided an opportunity to photograph the historic split bridge which opened to allow tall riverboats through.
