Oh yes.
Rosters also depend on fleet/base. Right now the Sydney guys are getting flogged. In Melbourne on the classic fleet we've got it pretty cruisy. In Cairns as an FO on the classic you're bored to death!
New Eastern EBA is now in line with the Sunstate EBA of: 8 or 9 days off per roster. Typical shift is a 5-and-3 overnight. There are some variations of this (e.g. Sydney also has day shifts and Mildura only has overnight shifts on the weekends).
DIVOSH!
