There is definitely a strong aspect of relationship with the barista/staff as has been mentioned.

In addition Australian's are known to be coffee snobs, anecdotally I've found even those that are not big coffee drinkers tend to be quite particular about the taste of their coffee.

If coffee roasting and preparation is held in high value and seen as somewhat of a craft it makes sense for Australian's to hold loyalty to particular roasters/baristas/cafe's. To draw a parallel, when getting a haircut many people will return to the same person if they are happy with the experience/result.

I'm particular as well, what I mean is there are a lot of high quality options rather than just one, which is great
