600 km North of Canberra? Not Brisbane.

Geography check: You cannot reach Brisbane by traveling 600 km north from Canberra.

• Canberra (ACT) – inland southeast (~35°S, 149°E).
• Brisbane (QLD) – northeast coast (~27°S, 153°E).
• Direct distance: ~950 km (590 mi).
• Driving distance: ~1,000–1,100 km (10–12 hrs via Hume Hwy / Newell Hwy).

What IS ~600 km North of Canberra?

• Dubbo, NSW (~390 km NW).
• Bourke, NSW (~750 km NW).
• Tamworth, NSW (~550 km NNE).
• Armidale, NSW (~650 km NE).
• Coffs Harbour, NSW (~850 km NE).

Brisbane is nearly double that distance. The premise confuses latitude/longitude geometry—Canberra is south of Sydney; Brisbane is north of Sydney. North from Canberra goes to NSW central/northwest slopes, not Queensland coast.
