"She's a nice lady, and she looks after me very well," he said.
"She looks after the apprentices like a son, so I am enjoying living with Paul and Leanne."
Prastiyou worked for leading Malaysian trainer Richard Lines, who often had up to 90 horses in work at his operation in Kuala Lumpur.
"When my boss sent me over, he said I had a bright opportunity here," Prastiyou said. "The opportunity only comes one time, so I'm going to ride as best as I can."
Prastiyou begins his engagements with the Alex Freeman-trained Alfie's Belle, who led and won at the Wingatui jumpouts on September 11.
"It seems like the horse has got plenty of speed from the gates, so 1000m will suit him, as will 3kg off the back, so he will run well,"
Aint No Lollygagga (R8) was scratched from Saturday in preference to today, when she takes on a rating 65 field over 1335m.
"It's a nice rating and standard for her so she should be all right," he said.
Prastiyou has established a good rapport with the No Excuse Needed mare, riding her in work, and guiding her to victory at Ashburton in July.
"She's a very 'on-the-bit' horse and she works really well - a wet track will suit her."
Ascot Park trainer Kelly Thompson has engaged Prastiyou for two rides, and he is keen on Ima Geegee (R7), who provided him with his second career win in October last year.
"She's got plenty of speed from the gates, so you don't have to hunt her out. You can just sit and get cover."
