Perth's leading apprentice Lucy Warwick is looking forward to riding in Melbourne but her parents are a little less enthusiastic.

The 17-year-old daughter of Perth trainer Justin Warwick joins the stables of Leon and Troy Corstens next week for a three-month stint.

She is in second place behind Willie Pike on WA's premiership table with 56 winners for the season, 32 in the metropolitan area and will start riding after January 20 when she finishes a careless riding ban.

Her father said he and his wife Carol were a little apprehensive about allowing their daughter to head to Melbourne but admitted the time was right while she was still able to use her claim.

"She's only got 31 or 32 winners left before she loses her claim," Warwick said.

"That should last most kids a year but's she's been winning two metropolitan races a week which gives her 15 weeks, so if she doesn't go now it would be too hard to get the chance as a 17-year-old with no claim.

"I think the worst case scenario is she will come back a better rider.

"I hope she goes over, does her three months and misses home terribly and comes home forever, but on the flipside I would like her to go and make the most of the opportunities."

Warwick only began riding in February last year and recently racked up her 100th career win.

The typical story of a young girl riding before she could walk fits Lucy who was basically born around horses.

Her mother was accomplished at show jumping, competing in World Cups, while Justin was a champion in harness racing before changing to thoroughbreds.

Lucy Warwick is excited about the impending trip and will head to Melbourne with no elaborate goals.

"I just want to ride winners and if I can't do that over there then all I want to do is come back here a better jockey," she said.
