AirNorth appear from the outside to have enough E jet pilots to operate that part of their schedule, so it would seem like the "gentlemen's agreement" is being honoured. I suppose a big question those crews might ask themselves is: should you jump to Alliance when the Qantas flying is currently a 3 year deal, especially if you don't want to move away from Darwin at the end of it? Lots of variables for an individual of course.
I probably should have been clearer, Alliance are advertising for type rated & vaccinated crew on their website. No idea if they're getting any yet. Lots of younger Australians in the USA flying E jets who might be ready to come home, former VA crews or miscellaneous others with the requirements and work rights for Australia.
