Big-race jockey Glen Boss is fed up with limited opportunities in Sydney and will kick-off a fulltime move to Melbourne at Moonee Valley on Saturday.

Boss, who returned from Hong Kong earlier this year, said the Sydney racing landscape changed dramatically during his time abroad.

"We've got the dominance of a couple of really big stables here and a lot of jockeys and only small fields and very limited opportunities," Boss told Sky Channel.

"I've come home from a year in Hong Kong and have just been bewildered by the lack of opportunities and lack of response from NSW racing that I have received.

"I'd say over the last 10 years that I have been nearly the most successful jockey in Australia.

"But I've got one ride at Wyong (on Tuesday) and one at Warwick Farm (Wednesday) and there wasn't much lined up for me at Randwick on Saturday either.

"My hand has been forced because I can't get a ride here."

Boss is most famous for his three Melbourne Cup victories aboard champion mare Makybe Diva and was a star of the autumn carnival with wins in two of Sydney's most prestigious races, the Golden Slipper on Sebring and Doncaster Handicap on Triple Honour.

"There's no sour grapes with anyone here, it's just the landscape of NSW racing and I needed to make a decision for me and my family," Boss said.

And while he is disappointed with Sydney racing, Boss is looking forward to starting a new chapter in his career.

"I've already spoken to the top 10 stables in Melbourne and I have been amazed with the response," Boss said.

"I think Victorian racing is in a healthy spot at the moment and it's only going to get better.

"I'm struggling to come to terms with what's going on here but I'm not somebody who sits on their hands and wonders `what if' and what could have been.

"As you saw when I decided to ride that filly (Samantha Miss) at 47.5kg in the Cox Plate, when I do something I do it well and when I make a decision I make it and give it 120 per cent when I do."

Boss said he would ride work regularly at both Caulfield and Flemington.
