The Nullarbor gap got smaller

The Nullarbor gap got smaller. On the Eyre Highway the charger spacing is now in the 175-to-200-kilometre band for most legs. That’s the news — the road as an electrified corridor.

EV Roadside’s mid-2026 crossing guide and mid-year Driven colour say the historic black spots on the crossing closed through the WA EV Network and South Australia’s RAA Charge build-out. The Stuart Highway still carries a Katherine-to-Tennant Creek hole around 625 kilometres. Network matured on one national spine. Frontier maths on the other.

The Eyre Highway crossing is roughly 2,700 kilometres end to end toward Perth. For years the story of that run in an electric car was the empty stretch — roadhouses without DC, gaps that punished anything short of a long-range unicorn. As of 2026 the published spacing across the crossing is generally under 200 kilometres, with many legs landing nearer 175. EV Roadside still flags one longer stretch around 260 kilometres between Mundrabilla and Nullarbor. Distance, for a modern EV with about 400 kilometres of highway range, stopped being the primary villain. Reliability took the job.

Where it’s true: the network matured. Western Australia’s Synergy and Horizon Power programme finished the WA EV Network build on the western approaches. South Australia’s RAA Charge network covers the eastern half of the plain. NRMA has put fast metal at Nullarbor itself. CCS2 for DC and Type 2 for AC are the ordinary plugs. Crowdfunded AEVA sites at places like Balladonia and Cocklebiddy still show up in first-hand crossing notes as the stubbornly reliable backups when a flashier unit is sulking. You can now plan a Nullarbor EV crossing the way you plan a diesel one — stop by stop — instead of treating it as an expedition lottery.

The Driven’s mid-2026 Nullarbor file is the honesty brake. Chargers on the Eyre National Highway from Norseman toward the South Australian border have fought reliability and capacity problems since the 2025 installs. Off-grid stacks — solar, battery, diesel — black out. Shared units trickle. A Norseman DC bay sat out of order for weeks in the reporting. Standard-range cars have burned half a day in queues and slow fills across a 650-kilometre band. Canola-oil generators showed up as temporary rescue kit at Mundrabilla when the next unit failed. Maturity here means the pins exist on the map. It does not mean every pin is green on PlugShare every Tuesday.

Treat the highway as the product. A national highway that carries wheat, tourists, and time-critical freight cannot treat EV charging as a hobbyist overlay. When gaps close to about 175–200 kilometres, the corridor becomes usable for mainstream battery cars. When a single off-grid failure reopens an effective 150-kilometre-plus hole to the next live plug, the corridor is still only as strong as its maintenance contract. Horizon Power accountability, battery-buffered 160-kilowatt-class units of the sort Energy Policy WA has awarded elsewhere, and live status apps are the pavement-equivalent of resealing. Kilometres of bitumen without working electrons are a half-built road for an electric fleet.

Stuart Highway is the contrast that keeps the Nullarbor win honest. Darwin south along the country’s spine runs about 3,000 kilometres to the southern end of that corridor. NRMA fast chargers at Katherine, Tennant Creek, and Alice Springs fixed the town nodes. The holes between Territory towns did not vanish with the ribbon-cuttings. Katherine to Tennant Creek still sits around 625 kilometres on the mid-2026 maps — EV Roadside prints the same leg closer to 670. Tennant Creek to Alice Springs runs about 500. Those are not 175-kilometre hops. Intermediate roadhouse DC is still being argued into existence under Driving the Nation and related programmes. Until those mid-corridor plugs are live and reliable, the Stuart remains a frontier crossing you verify charger-by-charger, not a Nullarbor-style under-200 pattern.

Australian Electric Vehicle Association crossing notes from 2026 rhyme with The Driven: decide your fast stops in advance; assume Plan B at every rural bay; expect roughly 20 percent less range on coarse chip seal than on a Hume-smooth freeway; watch the wind. Distances under 200 kilometres mean range anxiety yields to downtime anxiety. That swap is what a maturing network feels like from the driver’s seat. You're no longer asking whether the next charger exists. You're asking whether it will take a cable at 7 a.m. after a night of desert cold and a software sulk.

Corridor facts on one card. Eyre crossing: about 2,700 kilometres toward Perth. Typical EV gap now: about 175–200 kilometres, one outlier near 260. Stuart town gap Katherine–Tennant Creek: about 625 kilometres (mid-600s on EV Roadside). Nullarbor roadhouses live or die on off-grid integrity. WA EV Network and RAA Charge are the named builders that closed the historic black spots in 2024–25 into a 2026 usable pattern. NRMA at Nullarbor is the east-west handshake pin.

Energy talk runs to generation. Motoring talk runs to WLTP stickers. The road question is whether a National Highway still functions when the fleet’s fuel is electrons. Closing Nullarbor gaps to the 175–200 band is a pavement-era achievement measured in kilometres between plugs. Leaving a 625-kilometre Stuart hole is the unfinished section on the same national map. Both can be true in the same week.

People are crossing the Nullarbor in ordinary EVs in 2026 with planning and a Plan B. That was a rarer sentence five years ago. The network matured enough to make the sentence normal. Maintenance and off-grid robustness are the next reseal cycle. The Stuart’s mid-600s gap is the next missing lane. The Driven mid-2026 and EV Roadside’s trip guides are the maps under this. The road stays the protagonist.

PlugShare and Chargefox are the live instruments now. Kilometres between green pins replaced kilometres between roadhouses as the working measure, and a red pin on the Nullarbor can add 150 kilometres to the working gap overnight. That is still a smaller problem than the old empty map — and it is still a maintenance problem, not a fantasy about range stickers. Keep the apps open. Keep the Plan B socket list. Keep driving the corridor as infrastructure.

Eyre Highway. Nullarbor. Gaps about 175–200 kilometres. One longer Mundrabilla–Nullarbor stretch. Stuart Highway Katherine–Tennant Creek still about 625 kilometres. Network matured on the plain. Frontier maths in the Territory. The gap got smaller where the plugs landed.
