Origins of “Beyond the black stump”

The saying came about after a group of surveyors arrived on Astro station near
Blackall, in 1887. The surveyors used a blackened tree stump as the base for
their measuring equipment. The equipment was so large the tree stump was the
most secure base around. The surveyors were at Astro station to take
longitudinal and latitudinal observations, which were to be used in the accurate mapping of inland Australia. From there they were able to fix the position of all the major towns of southern Queensland.
The distance between Brisbane and Blackall is over 1000 km.

Where as the distance from Brisbane to Bourke is just over 920 km.

So, “beyond the black stump” is indeed further.
