In this global map of the geoid (Geoid99), the area in red in the South Pacific just north of Australia indicates a region where the Earth's gravitational pull is stronger. Here, the mean sea level is higher because the hypothetical ocean has been pulled towards this area where gravity is stronger. In fact, if you stood at sea level in the area near India (where the Earth's gravity is weaker) you would be a little bit lighter than if you stood at sea level just north of Australia in the South Pacific where the Earth's gravitational force is stronger.
