This map is one of the few on-line resources that allows a user to display standard Grid references as used by the RFS.

Click onto NSW, and then zoom into the Mt Wilson region. The centre cross-hairs are very useful for pin pointing a specific location before zooming in ot a lower level.

When you arrive at a satifactory level of resolution, select UTM grid On/off from the Menu section in the top right hand corner.

To derive the RFS format for a working Grid Reference, please see above.
