I found a set of photos in an album in the Memorabilia Room. On scanning them I can see it’s 22 Bty deploying to Tassie (traveling on C130 Hercs). The depot is 16 Bty in Launceston so the range would have been Stony Head Range on the NE coast of Tasmania. It would have been mid-late 1990’s.
No other details available at this time. Do you know anything more about this activity?
