I think i need to go back to basics. Let me check distances/driving times.
ok. Facts.
She's seen at 8.08am in Dalby on CCTV.
She's seen at 9.20am in Condamine BP on CCTV
Her Car is seen at 11.10am in Surat, heading south.\
Dalby to Surat, via Miles and Condamine is 3hrs 13min, not including the time taken to fill up. It's 1hr and 47min from Dalby to BP. She should arrive in Surat, no stops - at 11.21am

If we remove Miles; that's 2hr 49; again no stops; it's 1hr and 23 from Dalby to BP. Surat earliest would arrive is 10.57am.

This shows she likes to speed/high limit - because the earliest she should have been at the BP was 9.30am (1hr 23min from 8.08am Dalby, and if she went via Miles, it would have been 9.55am; a full 30min. And really, she's packing the car at 8.08am, so another few min there before leaving; then 50km roads in town etc.
Ok.I feel comfortable now that it's most likely she took the Kogan Condamine Rd, just based on time and distance and sighting.
I might self-delete parts of my post about her meeting foul play before Surat; I don't think there is any time. Thoughts?
