"What about the Leave, is it easy to get what you generally want?"
Generally yes, particularly if you apply early enough. And any days off required should not be a problem if the rosters have not been issued. The rosters are generally issued around the middle of the month, for the month after next i.e July roster issued by middle of May (don't think too many can beat that).
Rostering team considered to be pretty much the best in the business, constrained only by the numbers they have to work with.
