"There were some teething problems and it was a bit difficult at first in selecting the right horses because of the different weather conditions up there compared to the Downs.
"But, we got it right on Saturday and I flew home on Saturday night a happy man."
Hatch's four winners put him at the head of the Queensland trainers' list after the first Saturday meeting of the new season.
"I had a good season the one just finished with 66 winners and finished fourth in the provincial list," Hatch said
"We've got a team going to Mackay on Saturday, where I won the Cup a couple of years with Sayl, and then there's the Cairns carnival over the following two Saturdays."
Two of Hatch's winners on Saturday were piloted by Lacey Morrison, one by Justin Stanley and the other by Justin Huxtable.
Hatch rates Morrison as the best jockey in North Queensland.
Also on the program, Morrison ticked off the last remaining item on her bucket list of winning a Cleveland Bay Handicap.
