Norway's provider is
Avinor, and all though they are not actively in the foreign market, they are hiring. At the moment there are a staff shortage of about 100 in Norway (understaffed by 20-25%).
Recent employment of people from Denmark, Sweden, Iceland and Croatia is what I know about personally.
Sweden's
LFV has recently been accepting new staff from Norway to Malmo ACC, possible more.
What I heard from Denmark (
Naviair) is that they have too few positions to train on for student controllers, so a few of them actually now finish their education in Norway with an agreement with Avinor. If that also applies to experienced controllers, I don't know. Best way to find out is to send an email
hope that was some help.
