Yeah sorry nonikkers,
I was also told about the sea snakes but forgot to mention them. Sea snakes are actually the most venemous snakes in the world, far deadlier than the Taipan and king browns. One tiny bit would definately be fatal. Good news is they have tiny mouths and the fangs are actually towards the back of their jaw not on the front like a land based snake, so it is impossible to bit you anywhere but the webbing between your fingers on your hands.
Blue Ringed Occies are a real bastard and are quite tiny. I used to see a few in Botany Bay. One actually attached itself to the underside of my board one time whilst I left it in the shallows and went to land my kite. I picked up the board and it looked like a limpid until inspected more closely.
BR Occies are usually smaller than 5cm in diameter with legs outstretched and are a mottled darkish brown. They grow their electric blue rings when pissed off. They normally hang out in rock pools and under shells and stuff around the edge of the water. My ex wife picked up a large shell from the bottom whilst beach combing and it had a BR Occie under it. It was a miracle she wasn't bitten. They have a sharp single beak in the middle underneath so dont let em latch onto you or your screwed without hospitalisation.
Port Hedland sounds like a hoot, what with Large Tiger Sharks, Blue Ringed Occies, Stonefish, Stinging jellies, crocs and sea snakes. Fark! All of which can jump 6m and go for the throat

Perth sounds good, wind or no wind!
Good winds to you, you'll be right, just harden the f@#k up!
