Lots of down under types here who will help you out.
But you should really be looking at the US model as the exception, not the rule when it comes to EMS. Most other westernized systems, although having medical oversight and guidelines, do not have a doctor sitting at the end of a phone ready to tell the para what to do when they exhaust their SOPs. The para in the ambulance has the say in how they treat the patient, and is 100% accountable for their actions.
Those practitioners in NZ, Oz, UK, Holland, Canada, etc have their own license to practice. They do not work under a physicians license so treat as they see fit. There are guidelines which they follow, and there are restrictions and contraindications in treatment modalities like everywhere else, but are less protocol driven than the US. Many will use their guidelines as we use protocols - per the letter, but others can step outside them if they can justify their actions. Evidence based practice drives the practice of the modern day non-US para, and it is very progressive.
Those (damn) socialist countries also benefit from being able to utilize alternative clinical pathways for their patients. Not everyone who dials 911 needs a taxi ride to a hospital, and many times the patient can either be treated and left at home, or (at the ECP level) have prescriptions written for them for clinical imaging or other basic tests - wherein they can go to a doc-in-the-box center to follow up. No need for
mother may I at any time. It doesn't exist. The idea is to leave the emergency department for (shockingly enough) emergencies.
Education is also a major difference, and NZ has been the most recent of "other" places to adopt the bachelors degree for practice as a para. Yes, we can do that here if we want too, but our degrees are usually a hotch-potch of liberal arts and fire suppression stuff, which have little bearing on focused patient care. Talking of which, those other countries have EMS as a stand-alone entity, and have as much in common with fire fighting, as they do with horticulture. Masters degrees in EMS common these days, again with a focus on advance clinical practice. The money is also way ahead of the US. Here is a recent posting for a UK position:

Up to 80,000 Pounds per year - that's $126,000. I know some US paras can make that, but not for a 37 hour week. Before anyone chips in with taxation I have worked and paid tax in both countries for more than a decade in each - and under various governments. When all is said and done, there is little difference between the two.
But I digress...
In summary, there is no medical control in the countries you mention. It is a US thing.
I will link to the UK guidelines for you and will leave those funny-speaking types to do the same for their guidelines.
