Sent the will by email, however, if you use the link in Alan's post above for the Public Record Office Victoria page, you can see it there for free and there maybe more details in the original. After you search James Mathew and get his listing up, click on one of the links below that is highlighted. The files are all different sizes from 14,179 kb down to 1674 kb. I didn't open any of them because I'm on dial-up and it would be some day next week before that first file finished downloading!
Also, if you just search Mathew, no date, you will get listings for James and a George Mathew d. 1860 and Hannibel Mathew d. 1877.
Good hunting!
