Sheep were the basis of their wealth, and by 1850 there were more than 15 million head in Australia. Squatting was legitimized in 1836, after the British government recognized the impossibility of enforcing the original settlement restrictions.
When sugar is dissolved in water, the solution does not conduct electricity, because there are no ions in the solution. Some substances that are made of molecules form solutions that do conduct electricity. Ammonia is such a substance.
In solid ionic compounds, the ions are attracted to form a lattice and are unable to move freely and hence, they cannot conduct electricity. However, if you melt an ionic compound or dissolve it in water, these ions are now free to move around because the weak ionic bonds are now broken. The ions in these conditions are free to move and carry electrons between the anode and the cathode. As a result, the solution can be made to conduct electricity.
