About
the New South Wales Topographical Maps - As a rough guide the maps of
the following areas and east of them are nearly all at a scale
of 1:25,000, Tenterfield, Bingara, Boggabri, Gulgong, Mudgee, Orange,
Goulburn, Brindabella and Kosciusko.
Those that are west of these areas roughly up to and including Geera,
Condobolin, Hillston, Oxley, Swan Hill and up along the Murray River
are just about all at a scale of 1:50,000 and west of that are all
1:100,000.
The reference map shows these different scale bands very clearly -
