Full Coverage of the Telstra Prepaid Mobile Network
To check predicted coverage at a specific location, see our coverage map.
- Enter an address to check predicted outdoor coverage in your area
- Click on the map to view predicted outdoor mobile coverage at a specific location
- Use the arrow keys to pan and the +/- keys to zoom in and out.
No address? You can also search using latitude (e.g. -32.00000, 150.00000’).
Our predictive coverage maps show where outdoor mobile coverage is predicted to be available in accordance with the Telecommunications (Mobile Network Coverage Maps) Industry Standard 2026 and are a guide only. As coverage can vary, connectivity cannot be guaranteed at all locations where coverage is predicted.
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 Telstra mobile 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 car – the maps predict outdoor coverage only; when indoors or in a car, coverage is highly variable, as building structures or cars can reduce or even block the signal.
The nearer to the outer edges of our 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.
You can check predicted outdoor coverage by:
Find a location:
- Enter an address in the search box;
- You can also search using latitude and longitude (e.g., ‘-32.00000, 150.00000’).
- 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 the arrow keys
View coverage types
- Toggle between 5G and 4G to see different predicted coverage layers
The initial view shows predicted coverage for both 4G and 5G across all coverage levels.
You can use the legend to switch between 4G and 5G by selecting ‘4G’ or ‘5G’. To see more detail, enter an address, zoom in and click on a specific location on the map.
Coverage levels
Once you have selected an area, a text box will appear on the left-hand side of the map. This shows the predicted coverage level for your selected location, along with a description of the expected user experience.
Coverage Levels: Indicate 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

Important Information
Click on the Important Information link for more details on the predictive coverage maps, including information about coverage levels, and the limitations of predictive coverage maps.
Predictive 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 predicted coverage areas.
Here are some common factors affecting coverage 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 | Consider moving to a different spot – ideally away from the obstruction or to a more open area. |
| 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: If Wi-Fi is available, connect to it for your data needs, and enable Wi-Fi calling via your device settings. Move to a better spot: Try going upstairs, closer to an open window, or step outside if it’s safe. |
| Inside a car: Your cars body material, window size and metallic tinting can weaken mobile signals. | 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 Blue Tick device would benefit you. These phones have been tested by Telstra for enhanced antenna sensitivity, helping improve performance in weaker signal conditions and your overall mobile experience. Learn more about Blue Tick devices on the Telstra website. |
| 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 help with 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. |
| 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: If you have Wi-Fi available connect to it for data. Fixed networks can handle higher volumes and often experience different peak times than mobile networks. |
All Boost Mobile Prepaid plans include access to Telstra’s 5G non-standalone (5G NSA) network.
To access 5G, you’ll need:
- A 5G compatible device; and
- To be in a 5G coverage area.
