To be fair Barrow is near to everywhere in the UK compared to Adelaide in AU, the difference in scale between the distances is immense.
For example, the nearest city to Adelaide is Melbourne which is 725km. The distance from Barrow to London, let alone anywhere inbetween is just 350Km. From Adelaide to Perth is 2100Km. That’s the distance between Barrow and Rome.
Adelaide has to be a metropolis containing a bit of everything, Barrow does not.
Though if I had my time over and had to chose….. it would be Adelaide.
