No. The Great Barrier Reef is a marine biome, located in the Coral Sea, which is an arm of the Pacific Ocean. Freshwater runoff from floods is one of the dangers occasionally faced by the Great Barrier Reef.
yes
No. The snakehead fish is a freshwater fish.

you destroy it by attacking it and eventually it will break
No, platypuses live in inland freshwater environments in mainland Australia, not in the ocean.
Australia has two species of crocodiles: Estuarine, or saltwater crocodiles, and freshwater crocodiles. Both species are restricted to Australia's tropical north. The Estuarine crocodile is found across northern Australia, from near Broome in northwest Western Australia, across the Top End of the Northern Territory, to the Gulf country and Cape York of north Queensland. It can be found along beaches, around offshore islands (including those in Torres Strait and in the Great Barrier Reef), and in tidal estuaries and rivers, but it is not restricted to saltwater habitats. It has also been found in freshwater lagoons, rivers, and swamps hundreds of kilometres inland from the coast. The freshwater crocodile is also restricted to northern Australia, where it is found in inland waterways. Although usually a freshwater-dwelling creature, as it name suggests, it can live in the tidal reaches of some rivers. There are no crocodiles in either the Murray River or the Darling River, despite popular myth; nor are they found as far south as Brisbane or the Sunshine Coast.

As an island sinks, the fringing reef gradually becomes a barrier reef. If the island continues to sink, the barrier reef eventually becomes a signature atoll.
It is thought that the water that evaporates the fastest is fresh, with tap and saltwater right behind it. The salt is seen as a barrier to quick evaporation, which is why it is considered slower to evaporate.
