The moon was at the closest point to Earth in its orbit, making it appear about 7% larger and 15% brighter than normal.
The May full moon is known as the Flower Moon as it occurs when spring flowers are in bloom.
This Super Flower Moon will also feature the first total lunar eclipse in more than two years, during which the moon will pass through the Earth's shadow. It will appear red, which is known as a blood moon, because light is scattered through the Earth's atmosphere, much like during a sunset.
The eclipse will be seen in Sydney when the moon is much higher in the sky.
The eclipse was due to take place in the early morning hours in western North America, with people in Alaska and Hawaii poised to get the best views. It will also be visible in southern Chile and Argentina.
