Australia won gold on the very first night at Rio 2016. Thanks to Cate and Bronte Campbell, Australia broke the world record in the 4×100 metres freestyle final.

Even though the Campbell sisters made Australia proud by breaking the world record, they were not the one to secure the first gold for the country. It was Mack Horton who brought the first gold for Team Australia in the 400m freestyle.

The Campbell sisters, along with Brittany Elmslie and Emma McKeon, defended the title secured at the 2012 London Olympics. They created a new world record with 3:30.65, breaking the previous best of 3:30.98.

The earlier world record also belonged to Australia. The Campbell sisters were part of the world record at the Commonwealth Games in Glasgow 2014.

This was the fourth time Australia secured the title in the 4×100 metres freestyle category. The earlier wins came in 1956 and 2004.

More world records were broken on the first night at Rio 2016. Katinka Hosszu from Hungary broke the world record in women’s 400m individual medley final with a time of 4:26.36, ABC Online reported.

Another new world record came from Great Britain. Adam Peaty set a new world record in the men’s 100m breaststroke.

It was not easy for Team Australia to win gold in the 4×100 metres freestyle category, and the first 100 metres belonged to the United States. Simone Manuel was ahead of McKeon with a .05 advantage.

The second leg too belonged to the Americans who managed to establish a .61 advantage by the end of it. When Bronte took it from Elmslie, it was a different game altogether. At the 250-metre mark, Team Australia was trailing only by 0.07, thanks to the performance by the reigning world champion in 100m freestyle.

When Cate joined in, Australia was ahead with a .42 advantage. She secured the final 100 metres with excellence and won it for the country.

Rio 2016 saw Australia finish with a magnificent 1.24 advantage against the United States. Canada finished third with 3:32.89.
