Key takeaways
- On 25 June 2026 Transport for NSW replaced the TCAWS Technical Manual Issue 6.1 with the standard TS 05492:1.0 Traffic Control at Work Sites.
- The new standard adds requirements on end-of-queue management, crash attenuators and temporary speed zoning.
- Some supporting checklists and templates were still being developed at release, so check Transport for NSW for the current versions.
- Councils, utilities and older contracts may still reference TCAWS or other documents, so confirm which document each project specifies.
- Update your SWMS, TGS templates, inspection forms and crew briefings so they reference the right document.
Traffic control at work sites in NSW is now governed, for Transport for NSW work, by the standard TS 05492:1.0 Traffic Control at Work Sites. It replaced the TCAWS Technical Manual Issue 6.1 on 25 June 2026 and adds requirements on end-of-queue management, crash attenuators and temporary speed zoning. Other projects follow whatever document their contract specifies.
If you run crews, design traffic guidance schemes or manage road projects in NSW, this is the biggest document change in years. The good news is that the fundamentals have not been thrown out. The less good news is that a lot of paperwork across the industry still says "TCAWS 6.1" at the top, and some of it now needs to change.
This article explains what changed, what didn't, who it applies to, and a practical checklist for updating your systems. It is general information. Read the standard itself and confirm details with Transport for NSW before relying on any summary, including this one.
What was TCAWS and why was it replaced?
The Traffic Control at Work Sites Technical Manual, known across the industry as TCAWS, was the NSW reference for temporary traffic management for many years. Issue 6.1 was the version in use when it was replaced, and it had been amended after release.
Transport for NSW has now moved that content into its standards framework as TS 05492:1.0. The standard covers how temporary traffic management is planned, implemented, operated, inspected and reviewed on public roads in NSW. It brings earlier amendments into one document and updates the requirements in a few important areas.
Nationally, the Austroads Guide to Temporary Traffic Management (AGTTM) remains the common guide. NSW references it but applies its own standard, so TS 05492 is not simply "AGTTM with a NSW cover page".
What changed: TCAWS 6.1 vs TS 05492:1.0
Transport for NSW identified three headline areas of new or expanded requirements. The table summarises them at a high level. The detail sits in the standard, and it is the detail that auditors check.
| Area | What changed | What to check on your jobs |
|---|---|---|
| Document type | Technical manual replaced by a Transport for NSW standard | References in contracts, TGS and SWMS |
| End-of-queue management | Requirements added | How queues are planned for and warned |
| Crash attenuators | Requirements added | When TMAs are used, operators and certification |
| Temporary speed zoning | Requirements added or updated | Speed zone signs, approvals and records |
| Earlier amendments | Brought into the one document | Old amendment notices in your files |
| Supporting forms | Some still being developed at release | Current checklists and templates from Transport for NSW |
End-of-queue management
Queues that build back from a work site create their own crash risk, especially where drivers come over a crest or around a bend at speed and meet stopped traffic. The new standard puts more focus on planning for where queues will form and how approaching drivers are warned. In practice, expect TGS designers to think harder about queue length, advance warning, and whether devices such as VMS boards are needed. Our guide to VMS boards covers how they are commonly used.
Crash attenuators
Truck-mounted attenuators protect workers and stopped vehicles from errant vehicles. The standard adds requirements on their use. Whether a TMA is needed still depends on factors such as speed, traffic volume and the TGS. Operators need appropriate traffic control training plus the correct heavy-vehicle licence, and units must be inspected and certified as required and after any impact. See our guide to truck-mounted attenuators for the operational side.
Temporary speed zoning
Reduced speed limits at work sites only work if drivers believe them. The standard updates requirements for temporary speed zones, and Transport for NSW notes it reflects amended rules on road work speed limit signs. We explain the practical side in our article on work zone speed limits in NSW. Do not assume old speed zone practices still apply; check the standard and your approvals.
What hasn't changed
A lot of day-to-day practice carries over. The hierarchy of controls still applies: eliminate the risk where possible, then separate, reduce speed, warn, and use PPE last. A TGS still needs to be prepared by a suitably qualified person. Crews still need to set up to the approved plan, brief before starting, and record changes.
Inspections remain central. In NSW practice, work-site traffic control is inspected at the start and end of every shift and at suitable intervals during it, plus weekly and after-care inspections, all recorded on the project's forms. Older TCAWS guidance set at least two inspections per shift with two-hourly recommended; check what the standard and your contract now require and record accordingly.
Worker licensing is separate from the standard. SafeWork NSW issues Traffic Control Work Training cards under the WHS Regulation 2025 (NSW), and an employer must not direct a worker to do traffic control work without the right card. A change of technical standard does not change that duty.
Who does TS 05492 apply to?
This is the question that causes the most confusion on site.
| Type of work | Which document to follow |
|---|---|
| Works for or on behalf of Transport for NSW | TS 05492:1.0, as specified in the contract |
| Works on a state road under a road occupancy licence | The ROL conditions and the documents they reference |
| Council works or works on local roads | Whatever the council's permit or contract specifies |
| Utility or private developer works | The client contract plus the road authority's conditions |
| Events on roads | The event approval and the road authority's requirements |
Councils, utilities and older contracts may still reference TCAWS or other documents. If a contract signed before the change names TCAWS 6.1, ask the client in writing which document they want applied. Don't guess, and don't mix the two on one TGS.
What TS 05492 means for each role
The change lands differently depending on where you sit in the chain. This is a starting point for conversations inside your business, not a substitute for reading the standard.
| Role | What to do now |
|---|---|
| Client or project manager | Name TS 05492:1.0 (or the intended document) in new contracts and tender documents |
| TGS designer | Check queue, attenuator and speed zone arrangements against the standard before reusing layouts |
| Operations manager | Update templates, SWMS and forms; plan toolbox talks |
| Supervisor or ITCP holder | Know which document each job uses and run inspections to it |
| Traffic controller | Attend the briefing and ask if anything on site differs from what you were shown |
| TMA operator | Confirm your training, licence class and the unit's certification are current |
For clients, the practical effect may show up in quotes. If a TGS now calls for more end-of-queue warning or an attenuator where an older layout did not, the equipment and crew list changes. Ask your traffic control company to explain any differences rather than assuming the price has simply gone up.
Checklist: updating your business for TS 05492
Use this as a working list. Tick each item off with a date and the name of whoever did it.
- Templates: update TGS and TMP templates to reference TS 05492:1.0 where it applies, and keep a version for projects still on older documents.
- SWMS: review your traffic control SWMS for end-of-queue, crash attenuator and speed zone controls, and remove superseded references.
- Inspection forms: check Transport for NSW for current checklists and templates; some were still being developed when the standard was released.
- Speed zone records: make sure crews record when temporary speed zone signs go up, are covered and come down.
- TMA procedures: confirm operator qualifications, licence classes, unit certification and post-impact inspection processes.
- Crew briefing: run a toolbox talk on what changed, and record attendance.
- Job sheets: list the governing document and version on every job sheet.
- Client communication: tell regular clients how you will handle projects that still specify TCAWS.
Practical tips from the field
Most problems after a document change are not about the standard. They are about people working from memory.
- Write the governing document at the top of the pre-start. It takes ten seconds and settles arguments.
- Don't let old laminated sheets live in the ute. Collect superseded checklists and replace them.
- Brief supervisors first. ITCP holders run the set-up and inspections; if they understand the change, the crew follows.
- Watch the queue, not just the taper. With more emphasis on end-of-queue risk, have someone check how far traffic is backing up during peak periods and report it.
- Record everything that changes. If the set-up is adjusted, note what, when, why and who approved it.
Next steps
Read the standard, check Transport for NSW for updated templates, and work through the checklist above with your supervisors. For legal duties under WHS law, SafeWork NSW is the regulator. If you manage multiple crews, the TrafWise platform can help keep SWMS sign-offs, card checks and digital dockets current across every job.
Frequently asked questions
What replaced the TCAWS manual in NSW?
Transport for NSW replaced the Traffic Control at Work Sites Technical Manual Issue 6.1 with the standard TS 05492:1.0 Traffic Control at Work Sites on 25 June 2026. It covers how temporary traffic management is planned, implemented, operated, inspected and reviewed. Check the Transport for NSW website for the current version and supporting documents.
What are the main changes in TS 05492?
Transport for NSW has highlighted new requirements on end-of-queue management, crash attenuators and temporary speed zoning. The standard also brings earlier amendments into one document. Read the standard itself and the Transport for NSW summary material rather than relying on secondhand lists, because the detail matters for design and on-site practice.
Is TCAWS 6.1 still valid?
For Transport for NSW work, TCAWS Issue 6.1 has been superseded by TS 05492:1.0. Some councils, utilities and older contracts may still reference TCAWS or other documents. The document named in your contract, road occupancy licence or permit conditions is the one to follow, so check it and ask the client if unclear.
Do I need a new traffic control ticket because of TS 05492?
The change of standard does not by itself replace SafeWork NSW Traffic Control Work Training cards. Workers still need the right card for the work they are directed to do, and refresher training if they have not done traffic control work for two years. Check with SafeWork NSW or an RTO for current requirements.
Does TS 05492 apply to council roads?
It applies to works delivered by or for Transport for NSW and is widely used as best-practice guidance. Councils and other road authorities may adopt it or specify their own requirements in permits and contracts. Ask the council or road authority which document applies to your works before you prepare plans.
