The ON 1 survey marker on the
Hunt Oil Road marks where a Graded Line crosses the
Hunt Oil Road in a general east-west direction. The line is largely overgrown but the marker is clearly visible beside the track embedded in a concrete block with a star picket as a visual marker. The graded line is approximately 22 kilometres south of the Gunbarrel Intersection. The Graded Line tracks west at 293 degrees meeting the Gunbarrel after 12 kilometres. While terribly overgrown with no real track to follow, by keeping a look out for the small mounds of stone pushed to the sides by the initial grade of the track back whenever, and by taking visual lines, it remains fairly easy to navigate and maintain a straight line. The last several km of the line were heavily wooded forcing a winding route to finally reach the Gunbarrel. This Shortcut saves approximately 32 kilometres if travelling west on the Gunbarrel. From the
Gunbarrel Highway west, the
cleared line is used as an access track to the
Mungilli Outstation on the
Eagle Highway.
