Yes... like the worlds best subs !!
Collins-class submarine
*** The submarines have been the subject of incidents and technical problems since the design phase, including accusations of foul play and bias during the design selection, improper handling of design changes during construction, major capability deficiencies in the first submarines, and ongoing technical problems throughout the early life of the class. These problems have been compounded by the inability of the RAN to retain sufficient personnel to operate the submarines—by 2008, only three could be manned, and between 2009 and 2012, on average two or fewer were fully operational. The resulting negative press has led to a poor public perception of the Collins class.
The Collins class is expected to remain in service until the 2020s. Planning for a replacement class of up to 12 vessels commenced in 2007. The new boats are predicted to enter service from 2025, and be active until the 2070s

Despite the intense political debate over procurement of submarines in Australia, former US military naval adviser and submarine expert Bryan Clark said he had not been contacted by Government officials here.
The Federal Government is planning to build a fleet of 12 new submarines, thought to be worth tens of billions of dollars.
