Kooingal Station, Queensland, Australia

city AU -24.529, 150.427

Coordinate is the site of Kooingal State School (opened 1931, Shire of Banana, ~12km SW of Biloela, Central Queensland) per Wikipedia's 'Prospect, Queensland' article — used as the best available anchor for the Kooingal locality name; the 1893 marriage predates the school by decades so this is an approximation, not a precise pin.
