Auxiliary Oiler HMAS Sirius has reached a significant capability headmark, conducting her 500th replenishment at-sea on 7 September.
HMAS Melbourne had the privilege of the milestone refuelling, in an operation that also saw HMA Ships Parramatta and Toowoomba refuelled in a triple replenishment operation.
As a part of the multi-ship Indo-Pacific Endeavour deployment, Sirius is providing support for the largest Australian task group deployed in over 40 years.
Within a 24-hour period, the crew of Sirius reinforced their reputation for great service when they replenished HMA Ships Adelaide, Darwin, Parramatta, Melbourne and Toowoomba.
The activity as well as conducting two personnel transfers via helicopter, demonstrating its newly reinstated capability of aircraft operations for the first time in seven years.
To mark the occasion a handcrafted 500 flag was flown from the recovery line.
Midshipman Niamh Reading, who is currently embarked on Sirius and is completing her Naval Officer Year One engineering familiarisation, said the hard work was worth the experience she has gained.
“The 500th replenishment at-sea was an incredible moment to participate in, and a once in a lifetime opportunity for many sailors onboard,” she said.
“Having only posted to Sirius in the past month, I feel honoured to be a part of this achievement and I look forward to contributing to reaching various other objectives with the crew while deployed.”
Sirius will next head to the Indo-Pacific region as a part of the Australian Task Group which will work to provide support and enhance interoperability with regional nations, including the Republic of Korea, Japan, the Federated States of Micronesia, Malaysia, Singapore, Indonesia, Thailand, Timor Leste, India, Cambodia, Brunei and the Philippines.
