Many operators have minimum contractual requirements such as 250 on type for an FO or 500 on type for a Captain with ex amount of command. These are usually set by the big mining companies as most of the regional work supports it (Skippers, Network, Alliance, Airnorth, Skywest, Cobham etc).
Unless the operator has RPT routes to build you up, then they need to look elsewhere.
In the past two weeks I have had 5 operators offer me interviews. Some I sent resumes last year and never updated.
I know for a fact that most of the regional operators are ringing around desperately trying to get candidates to interviews and sim assessments.
Give HR a call and see what would make you attractive for an interview.
