Australia signed off from the pool on day one with a fifth gold medal in the water, winning the mixed 4x100m freestyle relay.
William Yang started things off before Kyle Chalmers swum an excellent second leg to take the lead. He handed over to Mollie O'Callaghan, who maintained Australia's advantage, before superstar Emma McKeon iced the race to finish ahead of England (silver) and Canada (bronze).
O'Callaghan's split was 52.62 seconds, while McKeon delivered a 52.21 split, which Ian Thorpe described in commentary for Channel 7 as "incredible".
Thorpe speculated McKeon was wearing a new necklace with charms for each gold medal but when quizzed about her bling on the pool deck by Cate Campbell post-race, the swimming superstar admitted she completely forgot to take it off before diving into the water.
"I forgot to take it off!" McKeon told Channel 7. "I forgot about it! You just reminded me."
