Pros & cons

The current path vs the MMA plan.

Cons: the existing system and current trajectory. Pros: the integrated MMA corridor programme.

Cons of the current system & plan

Australian Space Agency is small and underfunded

Established only in 2018, with a modest budget and limited capabilities. Sovereign space industry is aspirational rather than operational. The institutional infrastructure for a serious space programme does not exist.

No sovereign launch capability

Australia depends on launching payloads from other jurisdictions. No operating orbital launch facility on Australian soil. Sovereign satellite manufacturing is at boutique scale.

Satellite manufacturing offshored

Australian government and commercial satellite needs are met by purchasing from US, European, and Indian manufacturers. The technology base, supply chain, and skilled workforce for indigenous satellite manufacturing have not been developed.

Asia-Pacific launch demand currently served from elsewhere

Japanese, Korean, Indonesian, and emerging Asian commercial space markets are served by US, Indian, and Chinese launchers. Australia has a geographic advantage it is not exploiting.

Defence space capabilities limited

Sovereign space situational awareness, sovereign satellite communications, and sovereign launch are core national defence capabilities Australia largely outsources.

No serious launch geography utilisation

Northern Australia has some of the best launch latitudes on Earth - free delta-v advantage over Texas and Florida - and vast controlled airspace. None of this is currently being used at scale.

Pros of the MMA plan

World-class launch geography

Pilbara latitude of 20.7°S provides +16.9 m/s of free delta-v per launch over Starbase Texas. 285,000 km² of empty downrange desert. Controlled airspace, low population density, stable politics.

Asia-Pacific launch hub by default

Japanese, Korean, Indonesian, Singaporean, and Indian satellite operators reach orbit faster and cheaper from northern Australia than from any other regional alternative.

Sovereign satellite manufacturing on the corridor base

The Australian manufacturing base built for the corridor is the same base that supports satellite and launch vehicle manufacturing. A sovereign space industry on the same industrial platform, with no separate national investment required.

Defence and sovereign capability

Sovereign launch, sovereign satellite manufacturing, sovereign space situational awareness - all delivered as a side-effect of the broader industrial build.

Corridor power, water, fibre to the front gate

MMC Corridor #4 delivers gigawatt-scale electricity, industrial water, and fibre to Port Hedland and the spaceport site. No separate infrastructure spin-up - the corridor pays for itself before space services begin.

The Moonbase Test City and strategic talent pull

Terrestrial analogue facility for lunar surface operations - vacuum chambers, regolith testbeds, life-support, robotics. A long-term research and training programme that attracts the engineering and scientific talent Australia currently exports.

Cost and Return Summary

The dollar case for Space

CapexSovereign space programme capex is under SBC scoping — not in the current cost memos. Spaceport infrastructure, range and tracking, integration services delivery model are forthcoming in a dedicated memo. The integrated SBC manufacturing base (HVDC, steel, OCTG, precast, vessels) supplies most launch-vehicle and satellite-component requirements at scale.

Tier 1 — Direct SBC revenueNo direct SBC revenue from space. The SBC does not operate launch services or sell satellites — Australian space industry companies do, with the SBC enabling the underlying capability (sovereign manufacturing base, sub-10c/kWh electricity for cryogenic propellant production, corridor freight delivery of heavy launch components).

Tier 2 — Enabled outcomes and cascading upliftSovereign space industry revenue: $5–15 B/yr at maturity (under SBC scoping): Australian launch services, sovereign satellite manufacturing, earth observation, defence space contracts. Commonwealth share via tax flowback approximately $1–4 B/yr. The figure assumes Australia captures approximately 2–3% of global space industry revenue by 2050, up from approximately 0.4% today — on the back of sovereign manufacturing capability and cheap continental-scale electricity. Plus sovereign-capability cascade (Tier 3): talent and IP capture, strategic autonomy in space-based capabilities (communications, earth observation, defence). See Memo 20 §3.7.

Without SBC — what Australia spends insteadWithout SBC, Australia continues to lack a sovereign launch capability at scale. Space-based capability is purchased from US, EU, Japanese, or Indian providers. Strategic dependency continues.
