"Malone greatly improved the arrangements at the post, including creating the terraces as sleeping areas for close support troops. "From this time Quinn's Post, which was a vital position on which the whole Anzac defence depended, was regarded as fairly secure."
The terraces were just metres from the front line.
This year the survey team also recovered more than 100 artefacts depicting life on the battlefields, including three water bottles with bullet holes, medical bottles, a tin pannikin, tin food containers, expended ammunition, glass shards, shrapnel and barbed wire fragments.
These have been handed to the Maritime Museum at Canakkale, Turkey, for preservation.
The survey was a tri-nation undertaking set up after an agreement between the prime ministers of New Zealand, Australia and Turkey in 2005.
