In through the bottom hose, out through the top.
The direction of the flow in a toilet is determined by the design of the bowl and the direction of the water jets, rather than the Earth's rotation. Factors like the shape of the bowl and water flow patterns can influence the direction of the flow, not the location on Earth. The Coriolis effect, which impacts large-scale weather systems, is not significant enough to affect the direction of water flow in a small space like a toilet bowl.
Although the Coriolis Effect would tend to influence an opposite direction of flow, the actual effect is immeasurably small on the scale of household plumbing. Other, mostly random factors mean that the flow could be in either direction, or alternately in both.
Water flows in both directions regardless of hemisphere. In Physics, there is the Coriolis Effect that describes the flow/movement of water due to a variety of factors, and this is sometimes used to add validity to the myth, but the Coriolis Effect does not occur in small bodies of water such as a sink or toilet. The direction of water flow in a a sink or toilet depends on the direction that the water flows into the sink or toilet -- regardless of hemisphere. You can test this yourself by pouring a pitcher of water from the left side of a sink and then from the right side, you will see that the water will flow accordingly -- this experiment will have the same result in Sydney, Australia as it will in London, England.

In a river or stream, the flow of water is in one direction only.
In a river or stream, the flow of water is in one direction only.
Water flows in the direction of the open end of the pipe. You can visually observe the flow of water or use a flow indicator to see the direction of movement inside the copper pipe. Another way is to feel for the movement of water by placing your hand near the pipe to sense the flow direction.
