HMAS Kanimbla was a Kanimbla-class landing platform amphibious ship operated by the Royal Australian Navy (RAN). Originally built for the United States Navy (USN) as the Newport-class tank landing ship USS Saginaw (LST-1188), the ship was decommissioned in 1994 and sold to the RAN.

The 2005 Nias–Simeulue earthquake occurred on 28 March off the west coast of northern Sumatra, Indonesia. At least 915 people were killed, mostly on the island of Nias. The event caused panic in the region, which had already been devastated by the massive tsunami triggered by the 2004 Indian Ocean earthquake, but this earthquake generated a relatively small tsunami that caused limited damage. It was the third most powerful earthquake since 1965 in Indonesia.
