Port and industry already exist
Port Hedland is a working deep-water bulk port on the Pilbara coast. Heavy industry, rail, and a FIFO construction workforce are already there. That is not the same thing as a recovery architecture. Orientation of an existing industrial machine is the claim — not a greenfield city.

Western Sydney Aerotropolis is a working precinct
Western Sydney International (Nancy-Bird Walton) is a 24-hour airport at Badgerys Creek. The operator states passenger services from 25 October 2026. Bradfield City Centre and the Western Sydney Employment Area sit beside it. That is a surveyed precinct. A 150–250 MW compute / robotics load is not contracted and is not forwarded here as surveyed. No site inside the precinct is selected. Invitation, labelled Vision: Sydney Station.

Critical minerals, dated
Australia was the world's largest lithium producer in 2024 at roughly 36% of global mine output (Chile ~22%). The Pilbara also hosts iron ore at export scale and rare-earth feedstock (Mt Weld → Lynas). Minerals are a surveyed stock. Propellant and mid-stream processing are not automatic consequences.

Legal corridor is in force
The U.S.–Australia Technology Safeguards Agreement was signed 26 October 2023 and entered into force 23 July 2024. It is the treaty-level instrument for U.S. launch vehicles and related technology on Australian soil. AUKUS Pillar 2 sits alongside. The corridor exists. Access to it by an independent Australian entity is not evidenced.

Re-entry on Australian soil has been done
Varda's W-2 capsule — launched on a SpaceX rideshare — landed at the Koonibba Test Range, South Australia, on 28 February 2025: the first commercial spacecraft recovered on Australian soil, with further landings since. Approvals, range operations, and recovery logistics have been exercised. That is a range fact, not a Port Hedland berth.
belt: science
Dual-use sensing exists nearby
Space-domain sensing on the north-west coast (including the AUKUS-related radar at Exmouth) supports tracking and re-entry awareness. Earlier drafts placed DARC in the Pilbara; the correction is Exmouth. Sensing is not a crane that can lift a 52-metre stage.

Water is a constraint, not a backdrop
The Great Artesian Basin covers ~1.7 million km²; recharge is slow and localised. The Lake Eyre Basin covers ~1.2 million km² and is highly episodic. Any water-dependent pathway (process water, testbed, feedstock) must be engineered against these figures, not around them.

Free, Prior and Informed Consent is a hard door
No site selection, survey, construction, or testbed work proceeds over an identified sacred site or songline path without FPIC from the relevant Traditional Owners, in advance. Floor: Aboriginal Heritage Act 1972 (WA); Native Title Act 1993 (Cth); on the Sydney axis also Aboriginal Land Rights Act 1983 (NSW) and National Parks and Wildlife Act 1974 (NSW). FPIC is not the Native Title right to negotiate. Ceiling: higher than the legal minimum — Juukan Gorge (May 2020) is why. This brief names no specific sacred site.

Appin is named, not selected
Appin, Wollondilly, is Dharawal country (Cataract Gorge). On 17 April 1816 a camp was raided by the 46th Regiment; at least fourteen people were killed. The site was added to the NSW Heritage Register in 2022. On 24 July 1979 fourteen men died in the Appin colliery methane explosion. Aerotropolis West sits in the same south-west basin. That is not one nation claimed for all of Western Sydney, and it is not a site selection. It is why the unlit interior is not treated as empty. The dead are not a hook, and they are not forwarded as a Songline.

What this page does not claim
It does not select a site. It does not assert that Port Hedland is the optimal southern recovery port. It does not claim TerAustralis Incognita can operate a recovery berth. It does not claim a contracted megawatt load at Aerotropolis West. It does not claim a Telstra, Qantas, or Starlink partnership, an aviation install, native satellite voice, or 000 via Direct to Cell. Telstra Satellite Messaging (7 June 2025) and Select Satellite Apps (28 July 2026) are public. Qantas remaining off Starlink Aviation is public. CrystalCore as the layer when even that path is gone is Vision, held in document 08, and is not forwarded here as surveyed.
