The Government and indeed its predecessor have developed an integrated transport network that when completed will transform our lives, particularly in this region. When the current work programme is completed we will have a first class transport network that will compare favourably to the best in the world. It has not been without difficulties along the way, however, as Senator McDowell has indicated and Senator Tuffy has talked about; there is a level of inconvenience. There will always be inconvenience associated with development and construction. It is difficult for commuters and residents to sit through the construction phase of these many projects. It is largely due to the fact that the current network has reached saturation point and therefore there is not the extra capacity to allow for an unhindered existence through the period of construction and expansion of the relevant projects. This is clearly due to lack of investment by successive Governments. Senators on this side of the House must share in the responsibility as do Senators on the other side. Regardless of that, the importance of investment in our infrastructure must be recognised. I am proud of the achievements of the current Government and its predecessor, and in particular the commitment to our transport network at a time of relative constraint in our economic circumstances.
