NSW apprentice Shayleigh Inglese will be sidelined for five weeks after being caught with her mobile phone in the jockeys room.

Her master, Dubbo-based trainer Brett Robb, has also been penalised for knowingly contacting his apprentice while she was in the jockeys' room on at least two occasions including at Warren on June 2 and again at Gulgong on June 8, the day Inglese was found to have a phone in her possession by Racing NSW stewards.

Inglese and Robb both pleaded guilty to their respective charges.

She was suspended for two weeks, with one suspended for a period of two years, and a six-week ban, reduced to four weeks, due to mitigating circumstances.

The penalties, which rule her out of the saddle for five weeks in total, will commence after a careless riding suspension is served.

Robb, meanwhile, was fined $1000 for his indiscretions, of which $500 has been suspended for two years.
