The hull of the lead ship, HMAS Huon, was laid down during September 1994 at the Intermarine SpA Sarzana shipyard in Italy, and was transferred out to ADI's Newcastle facility as deck cargo, arriving on 31 August 1995.[5] Huon was completed in Newcastle in 1999, and the other five ships were constructed completely at the Australian shipyard, with 69% Australian content in the project.[5] All six were completed on schedule, with the last, HMAS Yarra, commissioning on 1 March 2003.[2][6]

So it took 9 years to build six minehunters...it does make one wonder if we have enough, and how to scale.

For comparison:
