"Te Akau Shark will most likely kick-off in an open sprint [at Te Rapa] here in New Zealand, and Melody Belle will probably have a few trials at home with a view to starting her off in the Futurity Stakes [group one, 1400m] at Caulfield."
Richards is looking forward to campaigning his stable stars in Australia in the new year.
"Melody Belle is a proven Group One performer and the Shark has plenty of x-factor, so we're very excited about their autumn campaigns," he said.
"Both horses did us proud during the Spring Racing Carnival.
"We would like to think they now have enough fans both here and in Australia to get into the top 10," he added.
"It's a great reflection of New Zealand racing that we have three high-profile horses entered for The All-Star Mile, and if they got there I'm sure all three would have a great chance of winning the race.
"Catalyst looks the real deal, he's head and shoulders above every other three-year-old over here, so I'm looking forward to seeing how he'll measure up in Australia," he said.
Nominations for the 2020 edition will close at noon (AEST) on January 9, with the voting period scheduled to open one week later on January 16.
