The Telstra Wholesale Mobile Network has predicted coverage areas in all Australian major cities, most outer-metro areas and larger regional centres, as well as many smaller towns and transport corridors. Check predicted coverage using the map below.

Predictive Mobile Network Coverage
Check our predicted 4G and 5G mobile coverage

These maps have been prepared in accordance with the Telecommunications (Mobile Network Coverage Maps) Industry Standard 2026 (Cth) (Standard) and show predicted outdoor mobile coverage based on predictive coverage modelling parameters prescribed by the Australian Communications and Media Authority (ACMA). Your actual experience and connectivity may vary.

Information and Guidance

Note: Our coverage maps indicate where outdoor mobile coverage is predicted to be available in accordance with the Standard and are intended as a guide. We’ve provided some tips on how to use the maps and what can affect your mobile experience.

 

Important! Coverage maps are a guide, not a guarantee. Mobile networks and signals are inherently variable.

 

While our maps give you a prediction of outdoor coverage in an area, your actual experience may differ because of:
 

  • Local conditions – buildings, trees, hills or other structures near you can obstruct the signal

  • Network load – lots of people using the network at the same time can slow it down

  • Your chosen phone – and some phones pick up the signal better than others

  • Being indoors or in a vehicle – the maps predict outdoor coverage only; when indoors or in a vehicle, coverage is highly variable, as building structures or vehicle bodies can reduce or even block the signal.

The nearer to the outer edges of the predicted coverage shown on the map, the more likely these factors will affect your experience. The predicted coverage applies to outdoor mobile network usage only.

 

For these reasons, we can’t guarantee a connection or a specific quality of service at every outdoor location shown on our maps.

How do I use the coverage maps?
Tips on how to use and understand the coverage maps

You can check predicted coverage by:

 

Find a location

  • Enter an address to check predicted coverage
  • You can also search using latitude and longitude
  • Or you can click anywhere on the map to view predicted coverage at that location

Move around the map

  • Zoom in and out using the +/- controls
  • Pan (move around) by dragging the map or using arrow keys 
     

View coverage types

  • Toggle between 5G and 4G to see different predicted coverage layers

 

Understand the map

  • Legend – shows Good / Moderate / Basic / No Coverage at the current zoom level (you can turn these layers on or off). 

  • Predicted Experience – shows the expected coverage level at the selected location for:
    • 4G
    • 5G

How do the coverage maps work?

The initial view shows predicted coverage for both 4G and 5G including all coverage levels.

You can use the legend to switch between 4G and 5G coverage by selecting ‘4G’ or ‘5G’.

To see more detail, or to:

 

  • Toggle specific coverage levels on or off; or
  • View whether 5G Standalone and/or 5G Non-Standalone is available at a location

Enter an address or zoom in and click on a specific location on the map.


What other details should I look for when searching a location?

  • Look for the text box on the left-hand side of the map. This will show the predicted coverage level for your searched location, along with a description on the expected user experience for that level.


What do the coverage maps show?

Our coverage maps show where outdoor mobile coverage is predicted to be available in accordance with the Standard and are a guide only. As coverage can vary, connectivity cannot be guaranteed at all locations where coverage is predicted.

What can affect my mobile experience

 

Coverage maps predict coverage based on factors such as tower locations and known large-scale obstructions (such as mountains and forests), but actual user experience may vary due to local conditions. Your mobile experience depends on both signal availability and signal quality, which may vary by location over time. 


Things that can impact your experience include:

  • Local conditions – buildings, trees, hills or road cuttings
  • Network load – how many people are using the network at the same time
  • Your chosen phone– and how you use your phone.


Because of these factors, your mobile experience may vary as you move around, as other users access the network, and depend on how you use your device. Variability is more likely near the outer edges of coverage areas.


Common factors affecting mobile experience and tips to help improve it

 

Factor

Tips to improve

Local conditions: Your signal could be obstructed if you are located near trees, a hill, building or other structures.  These obstacles can block or weaken the signal

Try moving to a different location, ideally to a more open area or away from the obstruction.

Indoors: Being inside a building reduces your mobile signal.  The impact depends on things like wall thickness, window size, metallic tinting and how far you are from the outside. 

Use Wi-Fi where available for data and enable Wi-Fi calling via your device settings.
Move to a better position, such as upper levels, near an open window, or outside if safe to do so.

Inside your vehicle: Your vehicle’s body can weaken mobile signals.  Phones placed below dashboard level (like on a wireless charger) can experience more signal loss than those near a window.  The impact also depends on factors like body materials, window size and metallic tinting. 

Mount your phone on the dashboard:  This helps keep it higher above the metal vehicle body and engine obstructions and closer to the window.

If you’re not driving:  Hold your phone near a window for better reception.

Your type of phone: Not all phones are created equal – some pick up signals better than others and not all devices support all features. Choosing the right phone can improve your signal strength.

Consider whether a device that has been designed for regional coverage would benefit you.

 

How you’re holding the phone: Your experience can vary depending on how you’re holding your phone.

Consider holding the phone away from your body or head. Most people naturally do this when scrolling or web-browsing but it can also be of benefit for voice calls – using speakerphone or a headset can make this easier.

Moving while on your phone: When you’re on the move you’re more likely to encounter obstructions that impact your signal quality (like those above) and your signal is also likely to be switching between towers as you move. For these reasons, your signal quality is likely to fluctuate.

Consider the tips above when you’re on the move, e.g. moving to a more open location or adjusting device position.

Crowds and traffic: Just like peak hour on the roads, mobile networks can slow down when lots of people are using them at the same time.  Even if you might otherwise have good signal quality, high traffic can affect overall experience.

Use Wi-Fi where available for data. Fixed networks may handle higher volumes and can have different peak demand times compared to mobile networks.
Device compatibility

These predicted coverage maps only apply to devices that are correctly configured and compatible with Australian mobile networks. However, we can’t guarantee compatibility for devices bought elsewhere. This is especially important if your device as bought second-hand or overseas.
