During part of the year the earth is aligned with the sun so that the Northern Hemisphere (the top half of the earth) is tilted closer inward towards the sun. As the earth continues moving around the sun the Southern Hemisphere is tilted inward, closer towards the sun.

Hope that helped.

Because India lies in Northern hemisphere and Australia in the southern Hemisphere.Due to the tilt of the eath's axis ,both experience opposite seasons at a particular time.
