Hello Nina,
I just googled for “Oman William” and this came up. (large download)
www.australian-history.com/samplers/AU7100-1860s.pdf
Index to the Victoria Government Gazette, 1860, Page 20.
Oman, William, deceased, administration to, applied for, 2012.
I suppose it means page 2012 of the 1860 series of Gazettes. I’ve no idea what sort of information the Gazette would contain. It might just be some sort of advertisement of the fact that the estate is under administration.
Better have a good read of this Public Record Office Victoria document. I think it is saying that the Administration record may be available online but first you have to get a number from the Victorian Probate Index available at the State and some local libraries etc. I couldn’t see anything about it costing anything.

I don’t know anything about Streatham and couldn’t find out much about it. I don’t think it would have been much of a place in 1860. Someone who died then in a fairly isolated farming area might have been buried on the farm if there was no organised cemetery. Did the Death Certificate give a clue?
I suppose it would depend on when the cemetery was established and whether records were kept for whatever they made do with before that. The Streatham database looks a bit like M.I.s rather than a record of burials, Coverage before 1900 looks very sparse with about 3 for the 1870s.
One of the Historical Societies at the top of the Streatham Cemetery page might know more (maybe Hamilton?). Or you could try Streatham Cemetery Trust, Mr. G Brown Secretary Box 18 Streatham 3351, 5350 7573 according to
