Leather Offcut or Scrap (Strathfield)

A random request. I have a winter coat which has a faux leather collar. The faux leather has splits now and the collar is looking rather tatty. I'd like to replace the collar portion with real leather so I am in search of a small fabric piece of real leather. Must be soft thin leather normally used in clothing such as leather jackets or pants. I'm after a dark tan colour like a horse saddle please.
Any suggestions where I might be able to source this economically is also appreciated. Thanks.
