Even more food for thought is the fact that RAN just shoved its first task group on patrol since most people in this forum were born. The last was Indian Ocean Deployment 1980, when a mate of mine went for an unscheduled swim from his Skyhawk when the carrier catapult went u/s.
Now we have Indo Pacific Endeavour 2017.

Six ships (one LHD, one tanker, four frigates), approx 1200 pers.

Due home at end of November.
