Mobile speed cameras
The primary goal of speed cameras is to reduce speeding and make the roads safer. Our 2011 performance audit on speed cameras found that, in general, speed cameras change driver behaviour and have a positive impact on road safety.
Transport for NSW published the NSW Speed Camera Strategy in June 2012 in response to our audit. According to the Strategy, the main purpose of mobile speed cameras is to reduce speeding across the road network by providing a general deterrence through anywhere, anytime enforcement and by creating a perceived risk of detection across the road network. Fixed and red-light speed cameras aim to reduce speeding at specific locations.
Roads and Maritime Services and Transport for NSW deploy mobile speed cameras (MSCs) in consultation with NSW Police. The cameras are operated by contractors authorised by Roads and Maritime Services. MSC locations are stretches of road that can be more than 20 kilometres long. MSC sites are specific places within these locations that meet the requirements for a MSC vehicle to be able to operate there.
This audit assessed whether the mobile speed camera program is effectively managed to maximise road safety benefits across the NSW road network.
The mobile speed camera program requires improvements to key aspects of its management to maximise road safety benefits. While camera locations have been selected based on crash history, the limited number of locations restricts network coverage. It also makes enforcement more predictable, reducing the ability to provide a general deterrence. Implementation of the program has been consistent with government decisions to limit its hours of operation and use multiple warning signs. These factors limit the ability of the mobile speed camera program to effectively deliver a broad general network deterrence from speeding.
Many locations are needed to enable network-wide coverage and ensure MSC sessions are randomised and not predictable. However, there are insufficient locations available to operate MSCs that meet strict criteria for crash history, operator safety, signage and technical requirements. MSC performance would be improved if there were more locations.
A scheduling system is meant to randomise MSC location visits to ensure they are not predictable. However, a relatively small number of locations have been visited many times making their deployment more predictable in these places. The allocation of MSCs across the time of day, day of week and across regions is prioritised based on crash history but the frequency of location visits does not correspond with the crash risk for each location.
There is evidence of a reduction in fatal and serious crashes at the 30 best-performing MSC locations. However, there is limited evidence that the current MSC program in NSW has led to a behavioural change in drivers by creating a general network deterrence. While the overall reduction in serious injuries on roads has continued, fatalities have started to climb again. Compliance with speed limits has improved at the sites and locations that MSCs operate, but the results of overall network speed surveys vary, with recent improvements in some speed zones but not others.
There is no supporting justification for the number of hours of operation for the program. The rate of MSC enforcement (hours per capita) in NSW is less than Queensland and Victoria. The government decision to use multiple warning signs has made it harder to identify and maintain suitable MSC locations, and impeded their use for enforcement in both traffic directions and in school zones.

Progress and measurement of the Premier's Priorities
The Premier’s Implementation Unit uses a systematic approach to measuring and reporting progress towards the Premier’s Priorities performance targets, but public reporting needed to improve, according to a report released today by the Auditor-General of NSW, Margaret Crawford.
The Premier of New South Wales has established 12 Premier’s Priorities. These are key performance targets for government.

Each Premier’s Priority has a lead agency and minister responsible for achieving the performance target.
The Premier’s Implementation Unit (PIU) was established within the Department of Premier and Cabinet (DPC) in 2015. The PIU is a delivery unit that supports agencies to measure and monitor performance, make progress toward the Premier’s Priorities targets, and report progress to the Premier, key ministers and the public.
This audit assessed how effectively the NSW Government is progressing and reporting on the Premier's Priorities.
The Premier’s Implementation Unit (PIU) is effective in assisting agencies to make progress against the Premier’s Priorities targets. Progress reporting is regular but transparency to the public is weakened by the lack of information about specific measurement limitations and lack of clarity about the relationship of the targets to broader government objectives.The PIU promotes a systematic approach to measuring performance and reporting progress towards the Premier’s Priorities’ performance targets. Public reporting would be improved with additional information about the rationale for choosing specific targets to report on broader government objectives.
The PIU provides a systematic approach to measuring performance and reporting progress towards the Premier's Priorities performance targets. Public reporting would be improved with additional information about the rationale for choosing specific targets to report on broader government objectives. The data used to measure the Premier’s Priorities comes from a variety of government and external datasets, some of which have known limitations. These limitations are not revealed in public reporting, and only some are revealed in progress reported to the Premier and ministers. This limits the transparency of reporting.
The PIU assists agencies to avoid unintended outcomes that can arise from prioritising particular performance measures over other areas of activity. The PIU has adopted a collaborative approach to assisting agencies to analyse performance using data, and helping them work across organisational silos to achieve the Premier’s Priorities targets.
Data used to measure progress for some of the Premier’s Priorities has limitations which are not made clear when progress is reported. This reduces transparency about the reported progress. Public reporting would also be improved with additional information about the relationship between specific performance measures and broader government objectives.
The PIU is responsible for reporting progress to the Premier, key ministers and the public. Agencies provide performance data and some play a role in preparing progress reports for the Premier and ministers. For 11 of the Premier's Priorities, progress is reported against measurable and time-related performance targets. For the infrastructure priority, progress is reported against project milestones.
Progress of some Priorities is measured using data that has known limitations, which should be noted wherever progress is reported. For example, the data used to report on housing completions does not take housing demolitions into account, and is therefore overstating the contribution of this performance measure to housing supply. This known limitation is not explained in progress reports or on the public website.
Data used to measure progress is sourced from a mix of government and external datasets. Updated progress data for most Premier’s Priorities is published on the Premier’s Priorities website annually, although reported to the Premier and key ministers more frequently. The PIU reviews the data and validates it through fieldwork with front line agencies. The PIU also assists agencies to avoid unintended outcomes that can arise from prioritising single performance measures. Most, but not all, agencies use additional indicators to check for misuse of data or perverse outcomes.
We examined the reporting processes and controls for five of the Premier’s Priorities. We found that there is insufficient assurance over the accuracy of the data on housing approvals.
The relationships between performance measures and broader government objectives is not always clearly explained on the Premier’s Priority website, which is the key source of public information about the Premier’s Priorities. For example, the Premier’s Priority to reduce litter volumes is communicated as “Keeping our Environment Clean.” While the website explains why reducing litter is important, it does not clearly explain why that particular target has been chosen to measure progress in keeping the environment clean.
By December 2018, the Department of Premier and Cabinet should:
- improve transparency of public reporting by:
- providing information about limitations of reported data and associated performance
- clarifying the relationship between the Premier’s Priorities performance targets and broader government objectives.
- ensure that processes to check and verify data are in place for all agency data sources
- encourage agencies to develop and implement additional supporting indicators for all Premier’s Priority performance measures to prevent and detect unintended consequences or misuse of data.
The Premier's Implementation Unit is effective in supporting agencies to deliver progress towards the Premier’s Priority targets.
The PIU promotes a systematic approach to monitoring and reporting progress against a target, based on a methodology used in delivery units elsewhere in the world. The PIU undertakes internal self-evaluation, and commissions regular reviews of methodology implementation from the consultancy that owns the methodology and helped to establish the PIU. However, the unit lacks periodic independent reviews of their overall effectiveness. The PIU has adopted a collaborative approach and assists agencies to analyse performance using data, and work across organisational silos to achieve the Premier’s Priorities targets.
Agency representatives recognise the benefits of being responsible for a Premier's Priority and speak of the value of being held to account and having the attention of the Premier and senior ministers.
By June 2019, the Department of Premier and Cabinet should:
- establish routine collection of feedback about PIU performance including:
- independent assurance of PIU performance
- opportunity for agencies to provide confidential feedback.

Managing Overtime: RailCorp and Roads and Maritime Services
Overtime is a significant cost for RailCorp and Roads and Maritime Services, adding about ten per cent to the cost of regular salaries. RailCorp’s overtime cost was $133.7 million in 2010–11, and at Roads and Maritime Services it cost $49.3 million.

Signal failures on the metropolitan rail network
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.

Connecting with public transport
We see considerable potential for the Ministry of Transport to plan and manage interchanges more effectively, so as to make better use of our public transport network. We believe that the Ministry now needs to focus more on multi-modal transport planning and interchange performance. It needs to assign responsibility for the coordination and oversight of inter-modal operations to an entity resourced for the purpose. Without this it will continue to be very difficult to identify and address unmet needs, seek and secure stakeholder funding, and monitor and evaluate system performance.
