Cate Campbell, her sister Bronte, Emma McKeon and Melanie Schlanger smashed the world record in the 4x100m world record in a time of three minutes and 30.98 seconds.
The Olympic gold medallists were a class above their Commonwealth competition and even greater than the great Dutch team of Inge Dekker, Ranomi Kromowidjojo, Frederike Heemskerk and Marleen Veldhuis who swam 3:31.72 in now-banned super suits at Rome.
England were in the Aussies’ wake with 3:35.72 and Canada in third almost 10 seconds behind with 3:40.00.
Earlier, McKeon won the individual 200m freestyle and Rowan Crothers set the world record for the men’s para-sport 100m freestyle.
The last time Australia held the world record for the 100m relay was at the Athens Olympics in 2004 with Alice Mills, Libby Lenton, Petria Thomas and Jodie Henry.
