Australia is only covered by mobile phone signal across 30% of its landmass. If you're relying on Google Maps in the outback, you're relying on memory — and memory from a platform that's never physically driven those tracks.

In this episode of Off Grid Down Under, Steve sits down with Sam Hayward, Chairman of HEMA Maps, alongside MDC's Banksy and Vaughan, to dig into 40+ years of mapping Australia's most remote country. From the company's Dutch founders laminating marine charts in Queensland, to sending the entire HEMA staff into the desert in pairs to remap outback Australia, to the Map Patrol vehicles that are still out there collecting ground-truth data today — this one goes deep.

We cover why Google Maps and Apple Maps fall dangerously short in remote areas, how HEMA's maps are actually made, the difference between the Smart Navigator and the app on your phone, and what kit Sam would recommend to any family heading out on a big lap.

In this episode:

• How HEMA Maps started — founders Henry and Margaret's story
• The Great Desert Tracks expedition of 1998 that remapped outback Australia
• Why Google Maps can get you into serious trouble in remote areas
• Australia's mobile coverage problem (hint: it's not 98%)
• Map Patrol — why HEMA still physically drives every track
• The Alpha Program: 50+ volunteer travellers collecting data on the road
• Smart Navigator vs phone app — which one's right for you?
• The biggest mistakes people make planning remote trips
• Physical atlas vs digital navigation — does one replace the other?
• What's coming for HEMA: HEMA Cloud, turn-by-turn offline, and more
