What ocean lies to the east of Australia?

The Pacific Ocean lies to the east of Australia, making it the correct answer. This extensive ocean is the largest in the world, covering a massive area that stretches from the Arctic in the north to the Southern Ocean in the south, and is bordered by many countries, including Australia. The proximity of Australia to the Pacific Ocean has significant impacts on its climate, culture, and economy, influencing everything from weather patterns to trade routes.

The other options refer to different bodies of water: the Indian Ocean is located to the west of Australia, while the Southern Ocean surrounds Australia to the south. The Atlantic Ocean is located much further away, on the opposite side of the globe. This spatial relationship helps clarify why the Pacific Ocean is the geographical feature that directly borders Australia on its eastern coast.
