Sister ferry Queenscliff returned to service last November after two new 2.5-metre wide propellors were installed during its dry-docking at Garden Island, joining the Freshwater on the Manly route.
The state government is spending $71 million on extensive refurbishments of three of the four Freshwater-class ferries, which covers the cost of dry docking.
Action for Public Transport spokesman Graeme Taylor said the navy had overreacted, and could have allowed the Narrabeen to be dry-docked because HMAS Supply did not need to be out of the water for the entirety of the repair process at Garden Island.
“It is a kneejerk response. You can refloat HMAS Supply while you’re awaiting delivery of parts,” he said. “The risk is that this whole process could go on and on, and the Narrabeen might not return to the harbour until October or November next year.”

A spokesperson for Transport Minister Jo Haylen said it was disappointing the Narrabeen could not enter dry dock this month but the needs of the navy and national defence “always come first”.
Two weeks ago, a Senate estimates hearing was told that HMAS Supply could be stuck at Garden Island for another year after spending the past 14 months tied up there for repairs.
Senior navy officials described the latest problem with a 19-tonne shaft in HMAS Supply as a “complex defect”, which was discovered during repairs to the warship over the past year.
A Defence spokesperson did not answer specific questions about HMAS Supply’s repairs at Garden Island, confirming only that her sister ship HMAS Stalwart is also in port in Darwin for an extended period due to engine defects.

As part of a $1.34 billion project, Spanish company Navantia built the two warships, which were commissioned in 2021. They carry fuel, dry cargo, ammunition and other supplies and equipment.
The youngest of the four large Manly ferries, called the Collaroy, was pulled from service indefinitely last September, and is almost certain to be retired because its operational and maintenance requirements are different to the other three Freshwater-class vessels.
Transport for NSW said it expected a decision within the next few months on the Collaroy, which is tied up at Cockatoo Island alongside the Narrabeen.
