How did you see the talent pool they are hiring from if you were helping someone look for a job and not helping someone hire for a job?
Did you ask companies to see their applicant lists and CVs or something?
Any of the meetups I've been to in Australia are mostly employed people(half only there to try and find other devs), recruiters and uni students or recent grads. Which meetups did you go to it would likely be worth adding them to my list for next time I'm in Melbourne.
