Perth Racing managing director John Yovich said the best thing about the Ascot celebrations was the nine-race card on track once the Cup had run.
TAB revealed that on Monday morning, a racing fan - seemingly very content with their selection - laid down $50,000 on Cross Counter to win at $10 for a potential payout of $500,000.
Morrison admitted he thought Marmelo and Hugh Bowman had stolen a winning margin at the furlong and said the six-year-old was simply beaten by a talented horse with a significant 4kg weight swing.
Cross Counter won the Cup, the Charlie Appleby-trained stayer handing Australian jockey Kerrin McEvoy his third Cup triumph.
Starting a $9 chance, Cross Counter settled in the second half of the field but producing a stirring finish to overhaul Marmelo ($12) who was initially being hailed the victor for Hugh Bowman.
Sheets and a tent were immediately put up to protect the horse and the tragic scene from shocked spectators, with some sharing photos online following the tragedy.
English trainer Charlie Appleby was full of praise for McEvoy's ride.
"I know how much this race means to him - he's been trying to win if for a while and so I am so happy this horse has been able to do it for him".
It was a relief for McEvoy, who was blocked when Aidan O'Brien-trained Cliffsofmoher pulled up lame early in the race.
Marmelo claimed the lead inside the final furlong of the $7.3 million race but was grabbed late by the fast-finishing Cross Counter who won by a length, with a further two lengths to A Prince Of Arran in third. He's the one that's given us the encouragement to take the chances in what we do.
The Cup victory notched up 30 Group One wins for Godolphin worldwide in 2018.
Appleby said the Melbourne Cup had been on his "bucket list for a long time".
"People under pressure make rash decisions, I hope we're making the right decisions now".
