How many times has Australia hosted the Summer Olympic Games as of 2026?

Explanation

Australia has hosted the Olympic Games twice. The first time was the Melbourne 1956 Olympics, where the distance to the rest of the world was truly felt. Travel costs and acclimatization caused major problems, so the number of participants dropped drastically and many countries did not show up at all. The next time was the Sydney Olympics in the year 2000, which had in advance gained a positive reputation as 'the best Games ever'. However, the topic of conversation later turned to the many positive doping tests, where, among others, the Bulgarian and Romanian weightlifting teams were penalized and sent home.
