I'm not sure if this Thomas Lee was an Australian local, that's what it sounds like. Maybe he's not my man. There was a few articles relating to him from the source you quoted (thanks for that) and they relate to general theft pre dating the Oct 1861 Horse theft...............
Thanks for the census details.
I see that Anc***ry gives a suggested record to New South Wales, Australia, Police Gazettes, 1854-1930 for a Thomas Lee 24 Oct 1861 for left.
A newspaper article has these details -
Bathurst Free Press and Mining Journal
HORSE STEALING.
Thomas Lee was indicted for stealing, on the 23rd October 1861, one horse, the property of
William Pearce.
Plea — Guilty.
Sentence — Five years hard labour on the public works of the Colony.
Unfortunately the above article make no reference to it being the Thomas Lee you are researching.
