Early morning reflections on a Kimberley cruise.

One of the best times on a Kimberley cruise is early morning on deck.  The rest of the world has not yet awoken.  There is a special satisfaction in strolling the upper deck whilst others are sleeping in. 
This is one of the simple highlights of cruising, taking in the soft tropical air before the heat of the day has commenced. 
At this hour of day, the emerging sun has a distinctive sparkle as another day begins.  I gazed at the far horizon, imagining that the early explorer Phillip Parker King may have perhaps felt the same way, centuries ago as he voyaged up this untamed coast.

A sudden movement on the starboard side caught my eye this morning as I was at the rail.  Looking down, I saw a large shape  surfacing.  On closer inspection I identified it as a large grey shark.  It had what appeared to be a very long tail.  We looked at each other for a moment, the shark seemingly surprised as I was at this unexpected encounter.

Then the creature vanished, off in search of an early breakfast I suppose.

But not before I took a quick photo to record this  strange dawn rendez-vous.  The idea of an early breakfast seemed a good one to me too, so I set off for the buffet, satisfied that I had seen an unusual inhabitant of the depths.  It would make a good story to tell my fellow passengers around the breakfast table. And the shark of course, would grow larger in my imagination as I recounted my sighting. .

Stowaway discovered on Kimberley cruise

Ships Log, Oceanic Discoverer 0600 hours.  I was taking an early stroll on the promenade deck this morning.  To my great surprise, I discovered the ship had gained another passenger during the night, lounging on the deck railing. 
To my inexperienced eye, it looked like some form of tropical mantis.  All the more remarkable as we were about ten miles off the Kimberley coast. A long way for a mere arthropod to fly. No wonder he felt like a rest !
Later when I reviewed my photo of the hitch-hiking insect, it didn't appear to have the large eyes of a praying mantis. The ordinary garden mantis as you may know, has quite bulbous eyes, which go red at night, and pink during the day.
If you look closely at the second photo, you'll see Arthur ( for want of a better name) has two ET style eyes, very small.  Other suggestions as to what species he could be, include a goliath stick insect ( eurycnema goloioth) or even a Giant Phasmid ( diapherodes gigantea). If the latter is correct, Arthur is probably aptly named, as the male phasmid is a bit smaller than the female.
What do you think Arthur is ?  Could he be a new species perhaps ?  Would be interested to know, and any feedback appreciated.
