Penguins drink any water they can get access to - fresh or salt. When ashore they will drink fresh water from pools and streams and can sometimes be seen drinking water preened off their backs during rain showers. At sea penguins must drink salt water and they are able to do this because they have special glands abound the eye sockets that extract excess salt from the blood. The excess salt is excreted as a salty fluid through the nasal passages.
They survive because their bodies, produce a chemical that filters the water that they drink +++ They don't. You cannot "filter" dissolved salt from water, but you can use osmosis, as do the penguins and other marine animals.
They get all their water through the things they eat.

Koalas rarely drink, but when they do, they drink only fresh water. No Australian marsupials can live on saltwater.
