The cache is not at the posted coordinates!
Four Knights, SirSingle, SirFace, SirCumference, and SirFeet wish to tour the chess board. SirSingle hopes to find an eligble maiden to become LadySingle. The puzzle requires you to follow SirSingles journey from the circled 2 reading the coordinates as you go. Coordinates are in full dd mm.mmm form. and the cache is a mint tin. No horses were maltreated while creating this puzzle.
Edit 25th March 2025. Seems it is a little more difficult than I thought, so have changed the D rating to D4. Also, SirSingle remains on the right hand half of the board.
The Fassifern rail line opened from Ipswich to Harrisville in 1882 and extended in stages to Dugandan in 1887. A line to mount Edwards branched off at Munbilla in 1916 and closed in 1960.
The Boonah line closed past Churchill in 1964.
The Puzzle:

The Knight can move to one of eight squares, as long as it stays on the chess board as shown by the ticks here.

Many thanks to groewrs who did beta tested this puzzle, and logged it with Nutty the dog while he was in the area last week.
