Adrian, Torres Strait is very shallow (7 to 15 m water depth) and can only be traversed through two routes:
(a) Endeavour Strait (purple line on chart) for small vessels.
(b) Prince of Wales Channel: Larger ships transiting Torres Strait enter the Prince of Wales Channel from the West just north of ****y Island by way of the Gannet or Varzin Passages. The minimum depths for deep draught sThere have been 14 groundings of bulk carriers and cargo vessels since 1970 recorded by AMSA, and historically, hundreds of shipwrecks hipping in the Great Barrier Reef pilotage area are found here (10.3m Nov 2011). Shipping with a 12.2m static draught or less are permitted to transit the area.[18].
However, we were discussing water depth at the port, not water depth in Torres Strait. It is 10 m at present (not your 200 m or even your 200 feet, and less than the 12 m static draught permitted to traverse the area). And that is a major limitation, although without knowing the configuration of the port floor, I don't know what might be achieved by dredging.
A bit like the guy who drowned in an average of 2 inches of water. :lol:
Torres Strait is Australian waters, with the border with PNG only a few km off the PNG coast, the only PNG waters being extremely shallow coastal waters. The Australian mandatory vessel reporting system requires all vesselsincluding those on overseas, interstate or intrastate voyagesto identify themselves and what their intended passage is through the region. The vessel can then be tracked as it moves through the Great Barrier Reef and Torres Strait. The port at Daru is outside Torres Strait to the east.
The assumption is always that China's motives are military, but ships are no longer very effective weapons in these days of accurate missiles and drones, particularly in a strait only 150 km wide, and at any point only 10s of km from Australia's Torres Strait islands. Quite possibly the aim is efficient fishing and the need for somewhere for fishing boats to refuel (China has a lot of mouths to feed). Which also may not be desirable, but PNG has not really developed its fishing industry. The Torres Strait Treaty allows Papua New Guinean nationals to fish in Australian waters - the Torres Strait islanders are now asking the Australian government to review this treaty.
There I go, waffling again...
