In the Southern Hemisphere, this happens when our side of Earth is tilted closest to the sun. As a result, the sun's rays hit the Earth more directly, leading to extended daylight hours and the sun appearing higher in the sky.
At the same time, the Northern Hemisphere will experience the winter solstice, due to the North Pole being at its farthest tilt away from the Sun.
The exact timing of the summer solstice varies by time zone.
So today Australia will bask in between 13 and 15 hours of daylight depending where you live.
