Between 2004 and 2006, the number of signalling failures, signalling downtime and the number of trains delayed as a result of signal failures all fell. RailCorp’s on-time running performance improved over the same period. The fall in failures is a clear indication of improved performance. Changes in the definition of on-time and to the timetable during 2005 and 2006 however make it difficult to determine whether improvements in response downtime and signalling delays are due to a true performance improvement. To build upon this strong base, RailCorp needs to determine with more confidence the number and duration of signalling failures the network can tolerate without impacting on service levels.

In our opinion the Government’s ‘no net cost to government’ requirement was a legitimate (but not the only possible) basis for the tunnel bid process. The Government was entitled to decide that tunnel users meet the tunnel costs. Structuring the bid process on the basis of an upfront reimbursement of costs incurred (or to be incurred) by the Roads and Traffic Authority (RTA) was therefore appropriate.

In our opinion, however, the Government, Treasury and the RTA did not sufficiently consider the implications of an upfront payment involving more than simple project cost reimbursement (i.e. the ‘Business Consideration Fee’ component). In addition, the RTA was wrong to change the toll escalation factor late in 2002 to compensate the tunnel operator, Cross City Motorway Pty Ltd, for additional costs.

The Audit Office is of the opinion that, while agencies are aware of the need to manage risk, their risk management falls short of better practice. Many agencies do not consider their risk management to be adequate. The survey suggests that some agencies, mainly those in the Public Trading Enterprise Sector have approached risk management in a systematic way and in accordance with the principles of better practice standards. Others, mainly departments not subject to commercial imperatives, have yet to progress the management of risk beyond the traditional response of insuring against the more common types of risk. Thus there is a danger that with a number of agencies, risk may not be managed adequately, especially in the General Government Sector.
