1871 Census, Perth area. Anyone have access to it?

I really need some help to find a George Young, wife Mary, daughter Annie, age about 21 at the time, son William age about 18 at the time. Dont know of any more children.
I am sure they lived in Perth . George was a mason.
The 1851 census would be of interest also if it is available.I would really appreciate some help on this as I do not live near any center that would have these films to peruse.
