It all depends Centurion'
If it was for the Cadetship, I'd say yes. If it was for direct entry, and you do not have, or are not close to the min Multi for command, then I would say yes.
If you do have, or are very close to the min requirements for command, then I would say give it your best shot. REX are going to need more upgradeble F/O's in the near future. A lot more. Promotion is running at approx 7 months, where at one stage not too long ago it was around 6-7 years!
If you read these threads carefully you will see a common theme. Flying for REX is in itself a rewarding and often challenging job. And therein lies the problem. For REX to be free of it's serious crewing issues the job needs to become a career in it's own right. LKH and his cronies say they cannot compete with the major airlines on the open pilot labour market. Bullsh!t! They choose not to compete because they are under the deluded opinion that this shortage of pilots will somehow turn around as quickly as it started. Well here's the news. This "shortage" has been coming for 10 years, and unless the airline operators (DJ, VA, and Jetstar included) start paying pilots what they are really worth, then this whole phenomenon will be with us untill they do!
