ON THE ROAD— Until 2007 there were no speed limits on highways in the Northern Territory outside built-up areas . Motorists were expected to “drive to conditions”. But in 2007 a 130kph speed limit was imposed to bring road rules more into consistency with states. Soon after it as elected, the conservative Country-Liberal Government reinstated open speed limits for a 200km section of the Stuart Highway between Barrow Creek and Alice Springs in January 2014. Later another section of 76km was added.

ON THE ROAD — The core elements of this stone cottage on the Fleurieu Peninsular were constructed about 150 years ago. The thick stone walls keep the building cool in summer and warm in winter. Just when the stylish copper wind vane was added to the chimney remains a mystery. The cottage is about 90 minutes drive from Adelaide and only a short drive from the ferry that connects Kangaroo Island to the mainland.

ON THE ROAD— Late afternoon and an unusual skyscape above the Arid Lands Botanic Gardens at Port Augusta, about 300km north of Adelaide. The afternoon was very hot and very humid and it looked like a storm might eventuate overnight. No storm, just rotten weather for sleeping brought on by the build up to full heatwave conditions the next day.

ON THE ROAD — Big trees and a little camper. We took delivery of our tear drop camper in Adelaide and yesterday we stopped for lunch at Poocher Swamp just out of Bordertown, near the South Australian/Victorian state borders. The trees are Red River Gums (Eucalyptus camaldulensis) and these are the dominant species at the swamp. These are not the biggest of their species at Poocher. One appeared in a news report in 1966 as measuring 10.5m in circumference and another was said to have a diameter at breast height (DBH) of 3.34m. The hydrology of Poocher Swamp is unusual and signs warn of the dangers of “runaway holes”. After good seasons Tatiara Creek quickly refills Poocher swamp and when it reaches a sufficient level it starts to flow quickly underground down these “runaway holes” which deliver surface water to aquifers. Some holes are permanent, but others can appear at random. When the flow is too much for these to absorb, outflow from the swamp goes downstream to Scown’s Runaway Hole. In floods in 1981 this hole was taking in water at a rate of 4,500 litres per hour.

ON THE ROAD — The Spiny or Jewel Spider (Austracantha minax) is found throughout Australia and exists in a variety of coloured forms, but always with a shiny, enamelled look. It’s only a small spider (females 10mm and males 3mm) but is common in brush and low scrub, anchoring webs between neighbouring bushes to snag passing insects. Each individual builds its own web but they often build close together so the webs are more or less inter-connected.

ON THE ROAD — on the way from Adelaide to Melbourne we took a little detour to visit the Ngarkat National Park which sits on the South Australian/Victoria border. Very few plants were in flower — we’d missed the nectar laden stems of the yakka grass tree and Banksia ornata was just coming into flower. We did see this white-eared honeyeater (Lichenostomus leucatis) waiting for better times. The flowering cones of Banksia ornata are a major food source for the two species of pigmy possums to be found at Ngarkat.
