Could someone in Australia try it and let us know please?

FYI: In the Northern hemisphere, it drains counter clockwise

Barry is right. Here, read it for yourself:

It's a total myth started by a radio station DJ.

Basically to get an effect would require an enourmous pool or pond; spanning enough of the globe to pick up the speed difference. If you look at a map of the world (all of us look with north at the top) you will see that the world spins from west to east. Surface speed at the equator is greater than any speed at higher or lower latitudes. Draw a circle for the earth with an arrow on the equator going from left to right. Now draw two rotating arrows that are 'driven' by the left to right arrow (think of them as wheels). The upper arrow will spin anticlockwise and the lower will spin clock wise Corriolis. This is exactly what happens with a tornado they tend to spin anticlockwise in north and clockwise in south.
But for the size of a bath it is probably more to do with the shape of drain and pure chance. If you swirl it the other way it will keep going that way.

The Coriolis effect which may well be in play if it have been greater desirable could reason all flows to be CCW interior the north and CW interior the south. despite the fact that, the main reason that bathroom water swirls is that it extremely is directed that thank you to greater helpful save the bowl sparkling. Water swirling in any draining pool or tub is a function of the graceful (as a results of fact the struggle by using an orifice is risky) stability of the flow out in the process the drain hollow and the geometry of the hollow with its bumps, screw heads, or in spite of else protrudes into the process the flowing water. it extremely is those disturbances which confirm which way the water flows out of a drain, no longer the Coriolis effect.

This is a serious answer, I'm not just here for the 2 points. Did you know that if you move your finger in the water you can make the water spin the other way? Try it next time you flush, then wash your hands and you can try it again.

The direction of drainage depends on local initial conditions and is not related to the hemisphere. Coriolus forces are much too weak to have any effect. This "myth" has been busted many times.

The opposite of Northern Hemisphere, which I can't remember the last time when I flushed... hmmm now I got something fun to think about next trip to the john.

You watched that Simpsons episode didn't you . . . actually though, I heard somewhere that water actually drains the same direction down there that it does in the Northern hemisphere.

This whole clockwise/counterclockwise thing is a load of garbage and has been proved to be so.
I can't believe it still survives despite being killed many times.

Barry is right. It's an urban legend. Maybe if you moved to a super-fast planet, rotating in one second instead of 24 hours, you would notice a difference.

Water flows counterclockwise in the southern hemisphere, as well as storm systems, whirlpools, and the toilet.
It called the corriolis (SP?) effect.
