The Monument Airport (PHQ)

The Monument Airport (PHQ), also known as Phosphate Hill Airport, is a private domestic aviation facility located in northwest Queensland, Australia. The airport primarily serves the Phosphate Hill phosphate mine and fertilizer plant operated by Southern Cross Fertilisers. It functions as a specialized 'Fly-In Fly-Out' (FIFO) hub, connecting the remote mining site to major coastal cities like Townsville and Brisbane via contracted charter operations.

The terminal infrastructure is functional and focused on the rapid processing of industrial personnel, featuring a single-story building with a sheltered waiting area and dedicated check-in modules for authorized staff. Because the facility is private and company-owned, it does not offer standard commercial amenities such as retail shops, public dining, or luxury lounges. Access to the airfield is strictly regulated, requiring Prior Permission Required (PPR) from the operator, and there are no public passenger services available on-site.

Operationally, the airport features a substantial 6,234-foot (1,900m) asphalt runway (14/32) capable of accommodating medium-sized jet aircraft used for corporate transport. Ground transportation to the nearby mine site and accommodation village is pre-arranged and managed by the mining company, with the regional center of Mount Isa located approximately 84 miles (135 km) to the northwest. Travelers should note that the airport is not a public entry point, and all logistics must be coordinated through the site's administrative office.
