When the lower Murray River was part of the ocean, some few million years ago, sea levels were 70 metres higher and atmospheric carbon dioxide levels very much higher.
Much of this is information worth reading and thinking about multiple times. In many coastal regions, fresh water and salt water alternates as being dominate. When dams or barriers of whatever nature are built, some traditional ecosystems are destroyed. Shrimp in the oceans, or Salmon, for only a couple examples, come into coastal estuaries or upstream in rivers to promote the next generation of their species. For flooding, dams can capture and release water to reduce flooding. Dams also have captured too much water causing more flooding upstream and then did emergency release of water that caused too much flooding down stream. CO2 does not control temperature and CO2 does not control sea level, we must study and understand the actual factors that are more important.
Some of the time frames are a bit of a guess. I think its plausible to suggest that the draining of Noahs flood off of Australia as responsible for most of the limestone cliffs.

For what it's worth, the Millenium drought began at the peak of solar cycle 23 and broke at the minimum between cycle 23 and 24.
