Senator Quinn's comments on public transport were interesting. The level of investment by the Government in national motorway projects is extraordinary, particularly in light of the under-investment in public transport. The strategic rail review has still not been published and I am beginning to understand why, particularly when one considers the recently published correspondence between the Ministers for Transport and Finance. It is clear that a major tussle is going on at Cabinet regarding the cost of investment in rail infrastructure and the commitments made to it and already made public by the Minister for Transport. With every week that passes and the failure to publish the strategic rail review, it becomes clearer that a battle is being lost by the Department of Transport. I will be curious to see the final publication of that review, how it differs from the leaks and what will be the bottom line, namely, whether funding will be provided to upgrade rail infrastructure.
