By bringing them to North America though, you are creating a bottle neck, and the breed will diverge from the originals in some way. The Siberian for example does not look or work exactly like the first imports did if you look at modern racing or show lines. The ones that are most like those are the ones working in a way as close to the original as possible.
Registries available for information and record keeping on this breed:
.Koolie Club of Australia
.Working Koolie Club
.Aus. Coolie Council
.International GC Society & Registry Aus.branch
.International GC Society & Registry USA branch
They all have a code of ethics and a breed standard (some differ from others), records of dogs and kennels. German Coolies have had a record kept of them in Aus and overseas by the IGCS&R.
I can't find a standard at the Koolie Club of Aus. There is no web presence for the Aus. Coolie Council or the Working Coolie Club.
You say they DO have a standard, yet, from the Koolie Club of Australia,
For this reason we have not laid down a 'breed standard' at this time as we accept that the different styles of Koolies suit the many and varied jobs they undertake. We also feel that we need to give the breed time to evolve a little before trying to mould the physical attributes to a 'standard'.
They do however, list this:

The Key Features of the Koolie
There are both key features and discretional features of the breed. I consider the
following to be the essential features: -
• A strong herding instinct.
• Sound temperament.
• Speed and agility.
• Stamina.
• Good sensory function - vision, hearing and ‘nose’.
• Appropriate conformation.
Which is laughably imprecise, except they go on to describe a standard. It includes:
(h) Eyes:
The eyes should be rounded and obvious, showing an intelligent and eager
expression. A strong stare of the eyes is important in maintaining the attention of the
animals being herded.
So there is no standard, except for one saying you should breed for an eager expression. You have what seems to be a breed club saying the breed must evolve, yet much of the membership is quite against this, at least from a non-herding perspective.
