At the Tollcross pool in Glasgow, Brisbane sisters Cate and Bronte Campbell, Melanie Schlanger and Emma McKeon, shaved almost three quarters of a second off the previous world record to win the 4 x 100m women’s freestyle relay.
“To quote Muhummad Ali, ‘we are the greatest'”, Cate Campbell told the Ten Network after the race.
“Not only a world record, a supersuits world record. This is the stuff dreams are made of,” she told Fairfax Media.
It was 20-year-old Emma McKeon’s second gold medal having already broken the Games record for the 200m freestyle.
McKeon is being called the new ironwoman in the pool as she qualified fourth-fastest for Friday night’s 100m butterfly final as well.
In the velodrome, flag-bearer Anna Meares, 30, broke another Games record to win the 500-metre time trial.
Her training partner, Stephanie Morton won silver – one of three silver medals for Australia on the opening day. The team also collected seven bronze medals.
In the men’s events, two gold medals were won with cyclists Luke Bobridge, Luke Davison, Alex Edmondson and Glenn O’Shea pipping England in the 4000m Team Pursuit and sixteen-year-old Rowan Crothers setting a new world record in the S9 100m Freestyle.
