[52] Mr Matters assessed the outlays anticipated from 1 December 2005 to the conclusion of trial. Mr Hartwell challenged the preparation for trial costs for senior counsel and suggested that the costs should be limited to 12 hours of conferencing with the six lay witnesses and 30 hours of conferencing with the five expert witnesses. He noted the further experts' reports fees which he describes as "at the higher end". The expert fees for conferring and preparing the reports are in the vicinity of $18,000-$20,000 each. In Mr Hartwell's opinion they should lie between $6,000 and $12,000 for each expert. Mr Matters' figures include conferring with those experts. The total of these outlays is $160,687.50. The total of those costs of $497,420.41. This includes the $300,000 which the plaintiffs have offered as security for the costs of the trial. Mr Matters' total, including those costs, is $836,293.76.
