Where is Chile in relation to Australia?

Answer 1

Chile is on the other side of the Pacific Ocean to Australia and at about the same range of latitudes north and south.

If your question relates to the volcanic ash plume coming from the volcano erupting in Chile but affecting air travel in Australia and New Zealand now, the ash has actually travelled from Chile not just straight across the Pacific Ocean but actually around the world in the opposite direction going the long way across Argentina, The Atlantic Ocean, Africa, The Indian ocean and then to Australia.
