McCullum was handed a four month disqualification in August after being found guilty of providing false evidence during an inquiry.

The inquiry was in relation to a 'potential breach of Racing NSW COVID-19 policy.'

McCullum was only granted her trainers licence in June last year and had three runners who finished outside the placing before the disqualification.

She said it was a harsh lesson to learn so early in her fledgling training career.

"I did the wrong thing and it's probably the wake up call I needed that I have to take responsibility for my actions," McCullum said.

"But I've done my time now and paid the consequences and I won't be making any mistakes like that in the future.

"I will certainly be a lot more aware of my responsibilities as a trainer.

"I've got no hard feelings towards anybody and have already moved on.

"I'm just looking forward to getting back to the races.

"If anything, it's just made me more determined to succeed as a trainer."

Group one winning trainer Gordon Yorke was the caretaker trainer for Cloverlea Farm while McCullum served her disqualification.

Yorke enhanced his reputation as a master trainer with seven wins and 11 minor placings from 41 starters.

However, his comeback to the training ranks was brief after he handed back his licence in late December.

McCullum said she aspired to emulate Yorke.

"Gordon did a fantastic job and had a lot of success in a short time," she said.

"Hopefully I can keep up the good work and it would be unreal if I could get similar results.

"Probably the thing I learnt most from Gordon is to be patient and to place your horses in the right races."

McCullum has 10 horses in work and hopes to have several of the stables runners ready for a first-up assault over the Albury Gold Cup carnival commencing on March 18.

"It's only a month before the Albury cup on Friday so none of my horses will be ready to race before that," she said.
