In Australia electoral boundaries set by the Electoral Commissions. Officers of those commissions are by law required to be politically neutral. For example, because I have been a member of a political party, I am ineligible to work for them.
There's a modest amount of argy-bargy every time the boundaries are redrawn, but in general seats are contiguous and have shapes that follow the population distribution.
