When humans first arrived in Australia, sea level was much lower than it is now. People could have taken the Northern route through Sulawesi, island hopping across the sea, then reaching Papua New Guinea which was joined to Australia. It is the most logical path because land could always be seen in the distance in times of good weather. The southern route is much more difficult in terms of resources and energy. It involves travel across large islands of the Indonesian archipelago from Sumatra to Timor then a considerably long sea journey to the northern part of Australia. Early arrivals obviously did not plan their journey, so using the easiest and most effective route was not an issue. They just moved east to new pastures as resources were depleted with new people moving into inhabited regions. It is possible that Australia was reached by travel along both routes. Artifacts in the rock shelter at Madjedbebe in Australia have been dated at 65,000 years before the present. Not much ar...

The common Sydney octopus does not look like a happy chappy, but he always looks gloomy. It is just the way he is. Not doing so well in the sea around New South Wales he has moved down to the cooler waters off Tasmania. Because they increased in number from a few early arrivals their genetic diversity is less than those on the east coast. More are arriving from NSW and Victoria so things are improving. The exodus began in the mid-2000s. A joint project between James Cook University, the Centre for Marine Socioecology (CMS) at the University of Tasmania and the Institute for Marine and Antarctic Studies (IMAS) is researching the genetics of the species. Gloomy octopuses have been found as far south as the waters near Hobart. A new study, published in the journal Scientific Reports, suggests the species is thriving in Tasmanian waters with a healthy mix of genes from local and interstate populations. The species, also referred to as the common Sydney octopus, or octopus ...

As fertile land becomes "all used up" with increasing demand for food we will rely more on the sea for nourishment, after we experiment with eating insects of course. Marine-based industries care little about the consequences of their actions at the moment. This has to change to make the oceans a renewable resource. Australia has the third largest controlled ocean territory in the world. This country has more responsibility than most countries. We allow nations to fish our waters but foreign fishing fleets seldom stay within the rules that are set. Overfishing is common. The Great Barrier Reef and Ningaloo are World Heritage Areas. We will have to protect and regulate more region around the coast of this vast continent. This may be selfish as we have a low population that enjoys to swim, dive, surf, sail and fish on an individual basis. However, with control comes responsibility. Australia's marine industry will rise from about A$40 billion to A$100 ...
