When passengers on a passing Sydney ferry waved the crew of submarine HMAS COLLINS really knew they were back "down under."

Near to an end was a voyage which began on June 6 and took CMDR Peter Scott and his 42 personnel as far north as Alaska.

On the way the lead boat of the Collins class was put to the test…and did indeed impress.

Patches of brilliant sunshine bathed the 3,350 tonne submarine when she traversed the Sydney Heads on Monday, November 20, and went to No 2 Buoy to be cleared by Customs.

After a short stay she moved on to Fleet Base East.

COLLINS's real welcome home will come when she reaches her homeport, HMAS STIRLING before Christmas.
