The final two corridors completing the continental grid. 20,000km total. Every resource centre, every capital, every coastal port connected. Design A full service stack. The Mega Factory cost curve reaches $6M/km.
~1,800km Western Australian north-south spine. Links the Kimberley to the Great Southern. Agricultural freight, mineral export, coastal tourism connectivity.
~2,700km. Crosses the continent at the resource belt. Links Queensland mineral wealth to Fremantle export. The final inland connection completing the continental grid.
Phase 3 corridors use Design A — the full service stack — built at Mega Factory maturity.
