Why do you see mustering as a step into ag. Why not just go and do your ag rating. The 5 hours dual for a mustering endorsement is only going to give you limited training for low level ops. If you want to get into ag then I would suggest you find a job mixing or loading for an ag operator. That way you are learning about the ag industry and at the same time you can be networking. That is not going to happen if you are on an isolated pastoral property.
Go for it.
