(1) I refer to the Government’s decision to re-route the Southern suburbs railway through South Perth-Como, and Salter Point and ask is it correct that the Ministerial briefing of the South Perth City Council emphasised that the compelling reason for the new route was to reduce the Mandurah-Perth travel time by 12 minutes?
(2) If so, what studies has the Government undertaken to determine the number of commuters who will use the daily service from Mandurah to Perth if the travel time is reduced?
(3) Will the Minister table such studies?

(2) Studies were undertaken for the original Master Plan, and further studies will be undertaken during preparation of the supplementary Master Plan. The relationship between improved journey times, frequency and patronage is well understood. The original demand modelling underpinning the patronage forecasts revealed that the elasticity of demand to changes in journey times is in the range of 0.54 - 0.63, in other words if there is an improvement in frequency and journey time of 10% there would be an increase in patronage of 5.4% to 6.3%. What is most important is the further modelling that is to be carried out in preparing the supplementary Master Plan for the Direct Route. (3) Yes - when the supplementary Master Plan is finished.
