"The track was pretty rough the other day and I have always believed she is better on top of the ground. I think the improved track conditions will suit her as well."
Moroney gave speedy 3-year-old She's A Thief a pass mark in her first start in Australia when sixth in the Listed Queensland Day Plate (1350m), but he has opted to make some gear changes ahead of today's Helen Coughlan Stakes (1200m).
"She is really good. I gave her a little jump out on Tuesday with blinkers and a tongue tie on, so she will have that change of gear to try and spark her up a bit," Moroney said.
"As a 2-year-old she had a lot of speed and she seems to have lost that a bit, so we are going to have a gear change to see if that is going to help her."
The main aim for She's A Thief is the Listed Gai Waterhouse Classic Fillies & Mares (1350m) at Ipswich on June 15.
On The Rocks represents the stable in the Group 2 PJ O'Shea Stakes (2200m) and Moroney believes the 4-year-old entire will strip much fitter after finishing towards the tail of the field in both the Group 2 Easter Handicap (1600m) and the Group 1 Doomben Cup (2000m).
"Being a stallion, he has got pretty strong and I think he just needed a bit of work. We had a lot of rain here [at the Sunshine Coast] and they didn't open the course proper.
"The all-weather track, which has serviced them well for a long time, is reasonably ripped up and not that good at the moment. They are just about to put a polytrack in instead.
"We didn't really have anywhere to have a decent gallop and I think he badly needed one going into his last start. We are hoping that run has tidied him up."
Moroney said his trio of runners were likely to stay in Australia and race in the spring before heading back to New Zealand for summer racing.
Meanwhile, Moroney has confirmed progressive stayer Gundown has joined his stable in Melbourne.
The winner of three of 18 starts for Murray Baker and Andrew Forsman, Gundown placed at Group 2 and Group 3 level as a 3-year-old.
The son of High Chaparral finished sixth behind Glory Days in the Group 1 Auckland Cup (3200m) at his most recent outing.
"We really think he is a country cups horse," Moroney said. "It has got a bit more difficult now there are a lot of imports but those sort of stayers are pretty easy to place in Australia.
"Strangely enough New Zealand doesn't have as many staying races. There are plenty of opportunities over here in Australia and I think things have slowed down as far as bringing the imports out."
