Black waters in Caley Valley Wetlands – An eco-bomb in the Great Barrier Reef?

What a coincidence that our due date (04/Jun) is the same day as the world ocean festival, or was it set to on purpose? This reminds me to have put some contents about the ocean.
A couple weeks ago, a Uni colleague brought my attention to the black water incident at Caley Valley, and I then did some researches online.

Apparently the two satellite images below lead to accusations against Adani, the mining company owns and runs the Abbot Point Coal Terminal in north Queensland. Both images were supplied by the Queensland government, and the left one shows the wetlands before the waste water release, whilst the right picture was taken after the Cyclone Debbie hit, in which the wetlands have obviously turned black.
 Before Waste Water Release
After Cyclone Debbie Hit

Most people got shocked by the change and debates have been focused on the following topics: 1. Is the water black or only appears to be black on the satellite image? 2. Is it a coal spill to the wetland or anything else such as magnetite? 3. Was it a natural wetland or a man-made swamp for duck hunting?
Although Adani has been arguing that the picture was simply because of different reflection, however the follow-up drone video clearly showed this was a lie. Adani then said the company had obtained the appropriate licence and there has been no breach to the conditions.
I have no idea on how the licence is set and under what regulation, but considering the already fragile eco-environment in the great barrier reef, shouldn’t more strict regulations be applied in this area? No matter it’s fault of Adeni or Debbie, coal or magnetite, dumping waste water to such an easily overflowed area is never a wise solution IMO.
