Melb does have its fair share of longshots.
I mean 20/1+ when I stay longshot.

I think those avgs for brisbane are distorted by short priced horses - even money etc.

Melb probably has more in the $10-20 range, but it seems Brisbane has more in the $20+ range, with $2 winners distorting the avg.

Anyway, if one can get onto a few of these, it don't matter where they are.
