Phase 0 is the Melbourne-to-Brisbane inland spine — 1,940km total. The new-build section is 465km from Western Sydney Airport — the SBC's proof of concept and the direct alternative to the government's HSRA tunnel. It runs from Western Sydney Airport north through Gulgong, Muswellbrook, and the Hunter Valley to the existing Newcastle infrastructure, and south from WSA through Canberra to the existing Melbourne network via Albury-Wodonga. Every metre is elevated on pylon beside the 168-year Main North freight railway — geology proven by 168 years of heavy freight, zero national parks disturbed, zero tunnelling risk.
Every Phase 0 pylon carries eleven parallel infrastructure systems. The compound value is the point — each service is more valuable because the others exist. HVDC pays for the corridor. The corridor makes freight viable. Freight makes the towns viable. The towns make maglev commercially sustainable.
| # | Service | What it is |
|---|---|---|
| 01 | HVDC POWER | 108GW at ±1,100kV. Six HVDC lines per corridor. Powers every city, town and mine site at 6c/kWh. |
| 02 | SOVEREIGN FIBRE | 96 fibre ducts. Gigabit broadband to every corridor town. Terabit backbone connecting Darwin to Singapore. |
| 03 | WATER CONDUIT | 1m community pipe (Phase 0) upgrading to full aqueduct (Phase 1). Spur connections to towns within 50km. |
| 04 | GAS + H₂ PIPELINE | H₂-ready X80 steel pipeline. Interlinks every Australian gas field plus PNG import. $6/GJ national gas price target. |
| 05 | FREIGHT RAIL ×3 | Three standard gauge electrified freight tracks. Double-stack hi-cube capable. 1,800m trains. |
| 06 | MAGLEV 500+km/h | Electromagnetic suspension. No contact, no friction, no track wear. Melbourne–Brisbane ~3hrs 53min. |
| 07 | HYPERLOOP SLOT | 6m structural slot built in at zero extra cost. Ready when hyperloop technology matures. |
| 08 | LPG PIPELINE | Liquefied petroleum gas distribution to every corridor town and industrial user along the route. |
No other infrastructure in Australian history generates revenue before it's finished. Phase 0 is self-funding by Year 3. The HSRA generates zero revenue until 2042.
⚠️ The CCN connection. The Sydney–Newcastle CCN line currently takes nearly 3 hours because passenger trains share track with freight. Remove the freight — send it inland on Phase 0's three dedicated electrified tracks — upgrade the CCN surface line to 200km/h, and Sydney–Newcastle drops to 60–65 minutes by 2028. No tunnel. Cost: ~$3–5B. The HSRA tunnel achieves 45 minutes by 2042 for $93B. The difference is 15–20 minutes, $88–90 billion, and 14 years. Phase 0 solves the Sydney–Newcastle problem as a side effect — the freight comes off the coast and goes inland, through Robertson.
These are structural facts, not preferences. The HSRA tunnel fails on cost, risk, timeline, services, and geography simultaneously.
| HSRA — Government Plan | SBC Phase 0 — MMP Plan | |
|---|---|---|
| Cost | $93B stated. BCR "not possible to assess" — Infrastructure Australia, Nov 2025. | $88B volume. BCR positive from Month 20. Revenue before completion. |
| Tunnelling | 115km continuous tunnel. Hawkesbury, Hornsby Plateau, 9 national parks. | Zero tunnels. Elevated pylon on proven 168-year freight corridor. |
| Services | 1 service: passengers only. No freight, no energy, no water, no gas, no fibre. | 8 services: freight ×3, maglev, HVDC, fibre, water, gas + H₂, LPG. |
| Opens | 2042 at earliest. HS2 ran 3×. Snowy 2.0 ran 10×. No upper bound given. | Planning now. Build target 2027+. Operational well before HSRA 2042. |
| Revenue | Zero until 2042. 16 years of interest accumulation on $93B. | $4–6B/yr HVDC from Month 24. Self-funding by Year 3. |
| Robertson | Does not come within 500km of Robertson. Zero benefit to Robertson or the Central Coast. | Phase 0 terminates at Newcastle. CCN upgraded separately $5–8B. $10 fare preserved. 90min Newcastle–Sydney. |
| Freight | Zero freight electrification. Not mentioned in HSRA proposal at all. | First electrified freight in Australian history. 70% cheaper to port. |
| Stations | Six coastal suburban stations. All Labor electorates. Zero inland. | Maitland, Singleton, Muswellbrook, Gulgong — Hunter Valley communities the HSRA ignores. |
| Sydney–Newcastle | $93B tunnel → 45min, opens 2042. 15min faster than a surface upgrade. | Remove freight → upgrade CCN surface → 60–65min by 2028. ~$3–5B. No tunnel. |
| Land | Compulsory acquisition. Farmers compensated once then removed. | Lease: 1,250 farmers paid $160–320K/yr permanently. They support it. |
| Cost risk | Flyvbjerg 50%+ overrun risk: $140B+. Snowy scale: $930B+ for 1 service. | Cost risk contained: no tunnelling, proven terrain, phased revenue offset. |
| Decision | 2028 FID locks it forever. No independent review. No comparison. | MMP demands independent review and parallel design program before 2028. |
