Freshly escaped from our double encounter with the dinosaurs, we at East Coast Car Rentals figured that it would be prudent to head back to the present day and leave T-Rex and his chums alone for a while.
That doesn't mean that we're quitting our intrepid trek across Australia in discovery of the weird and wonderful, so leap into your hire car and set your satellite navigation system to 'strange.'
The Burning Mountain, Wingen, New South Wales
There is a fire that never goes out, and it can be found at the the Burning Mountain, near the town of Wingen. For over 6,000 years, a coal seam fire has been frying its way through the mountain at a rate of one metre per year, covering nearly 7 kilometres since it was ignited by what was thought to be a lightning strike all those years ago.
Coal seam fires are very common, but when they are discovered they are usually put out within a matter of a few days. Because these kinds of fires don't tend to last for a particularly long time, the Burning Mountain is something of a phenomenon, almost like a volcano without the attendant molten lava.
SS Ayrfield, Homebush Bay, New South Wales
Many moons ago, Homebush Bay was once the hub of Sydney's industrial heart. But that was before the dumping of toxic waste barrels underground caused the area to become unsafe, with fears that the chemicals such as Agent Orange could contaminate drinking water and the surrounding land.
The SS Ayrfield didn't collapse and sink as others did – it stayed upright, floating aimlessly like a phantom vessel across the still waters.
As the area was abandoned, so too were the commercial freighters that were used to transport goods to and from across the port. One of these was the SS Ayrfield, a ship built in 1911 but left to rot once the industrialists had left.
However, the Ayrfield didn't collapse and sink as others did – it stayed upright, floating aimlessly like a phantom vessel across the still waters.
The really incredible thing about the SS Ayrfield though isn't that it remains afloat after been neglected for the best part of half a century. No – it's more the fact that she has grown a miniature forest of mangrove tree across her decks with branches and leaves sprouting from every nook and cranny that they can find.
Eventually, though, the trees will be the undoing of the SS Ayrfield. The roots are digging further and further into the ship's hull, slowly breaking it down. In due time, the hull will collapse, causing the ship to finally sink. Or will it?
