For the past 12 months, Horner has been training in partnership with his father Darryl but has now branched out on his own.

He has 15 horses in work including recent stable addition Liberty Heights, a lightly raced three-year-old by Statue Of Liberty.

Liberty Heights made her Tasmanian debut at Mowbray four weeks ago when third to Havana Stash and Incum Coming in the Magic Millions 3YO Classic.

She was only narrowly beaten and drops back sharply in grade to contest tonight's Tasbonus 3YO Maiden.

Horner, who is also a horse dentist, is hoping to build on his stable numbers as he develops his private training facilities not far from the Spreyton track.

"We've got a treadmill, walker and our own training track which is cinders at the moment but we will put sand on it," Horner said.

"We can definitely cater for more horses."

Horner also has recent Mowbray winner Yellow Tagh, Five Star General, Cool Partner and Yasir engaged at the meeting.

In tonight's main race, the Carlton Draught (Bm78) Handicap, smart mare Terra Amata will be having her last start in Tasmania.

The four-year-old is to continue her career in New South Wales with trainer Kris Lees.

Terra Amata has raced 17 times for the Charlie Goggin - Luella Meaburn stable, recording five wins and eight placings.

Part-owner Joe O'Neill said he expected the mare to do well in Sydney, after first going for a spell.

"She hasn't been far behind the good mares in the Bow Mistress and Vamos Stakes at her past two starts," O'Neill said.

"Charlie and Luella have done a great job with her but there are more opportunities for her interstate."

Terra Amata comes up against a small but select field, with Just A Beach, Difrent, Devil's Tears and Ladali all recent Mowbray winners.
