saltwater

Desalination is a widely used method to produce potable water, however an energy-intensive process is required to separate the dissolved salt in saltwater.

The huge saltwater crocodile lived in the sanctuary on an island off the coast of Queensland since being caught in Australia's Northern Territory in the 1980s.

Its icy crust is up to 25km thick, and sloshing beneath, there could be a vast saltwater ocean.

Scientists believe Europa has liquid water in the form of a large saltwater ocean beneath its icy crust.

The new rules bring the NT in in line with every other state and territory in Australia - except, oddly, Victoria, which is well outside of the comfortable climate of a saltwater crocodile.
