The watercourse Splinter Creek from which the locality presumably takes its name enters the locality from the north (Cannindah / Ventnor) and forms the locality's north-western boundary before flowing south through the locality, then forming part of the south-western boundary, then flowing through the locality to the south, where it forms part of the southern boundary of the locality before exiting to the south-east (Tellebang).[3]
The land use is predominantly grazing on native vegetation with some crop growing.[7]
