Melbourne Cup-winning jockey Mark Zahra says it is "unbelievable" that he guided Gold Trip to victory.

Zahra rode brilliantly to guide the French stayer to victory, less than three weeks after it finished second in the Caulfield Cup.

"I can't [put this into words]. I feel like crying. It's unbelievable. What a day," he said.

"He's a horse that when you go, you don't give him a chance to think about it. I was hoping no-one would come near me."

Emissary finished second and High Emocean came third.

Favourite Deauville Legend finished strongly, but could only manage fourth.

An emotional Zahra spoke of the difference between 2022 and last year, when he was suspended and lost the ride on eventual winner Verry Elleegant.

"This time last year [I was] in Byron Bay and I was getting told off for drinking too much and it could have been my ride," he told Channel 10.

Zahra said his wife was asking him not to drink too much after the race.

"I said, 'What do you want me to do? My horse just won the Melbourne Cup?' For today, to come today and I've got good mates in the horse and it's unbelievable."

More to come.
