He said his accountants had advised him to close his stables at the end of the financial year and not drag matters out.
"The costs here for rental, staff, superannuation, raceday fees and the like are too high to be compensated by the prize money level.
"I know they have announced the industry will be getting more prize money because of the wagering deal but I don't think it will flow through for at least another 12 months."
Treloar said stable rentals were a prime example of the difficulties trainers faced in Queensland compared with some other areas.
"I rent 32 boxes at Caloundra which roughly costs me A$10,000 a month. I had 40 boxes in Singapore and that cost me A$80, yes A$80, a month.
"I am about A$120,000 behind a year before I even get started by training here. The return here just isn't up to correcting that difference."
Treloar said another problem was that many Queenslanders who could afford to race horses had them with trainers in Sydney and Melbourne.
"You can't blame them. If they have a good horse you want to get the maximum return," he said.
Treloar said he would continue to be associated with racing and would stay on the Sunshine Coast until the end of the year.
