Does the water swirl differently in Australia than America or any other northern hemispheric country?

The Coriolis effect is a force that acts on objects moving in a rotating reference frame. In fluids, the Coriolis effect causes a swirling motion called a vortex. The direction of the vortex depends on the direction of the rotation and the hemisphere in which the fluid is located.

In the Northern Hemisphere, the Coriolis effect causes the water in a draining sink or toilet to swirl counterclockwise. In the Southern Hemisphere, the water swirls clockwise. This is because the Earth is rotating counterclockwise around its axis, and the Coriolis effect is a force that deflects objects to the right in the Northern Hemisphere and the left in the Southern Hemisphere.

The Coriolis effect also affects the direction of winds and ocean currents. In the Northern Hemisphere, winds and ocean currents tend to move in a counterclockwise direction, while in the Southern Hemisphere they tend to move in a clockwise direction.
