Telstra vs Optus vs Vodafone: Getting Better Phone Signal at a Rural Property in Australia
Published
Weak signal on the farm or acreage? How to test outdoor signal, pick the strongest of Telstra, Optus and Vodafone at your address, use Wi-Fi calling, place an external antenna and size a booster kit.
Short answer
At a rural property, the best fix starts outside. Walk the property with Wi-Fi off and note the signal in dBm for Telstra, Optus and Vodafone, because the strongest network can change from one farm to the next. Use the carrier with the best outdoor reading, turn on Wi-Fi calling if your carrier and phone support it, and if there is usable signal outside, mount an external antenna high and facing the tower, then pick a kit sized to the floor area you need to cover.
Why rural properties struggle for signal
Out of town, the nearest tower can be many kilometres away, and hills, gullies, tree lines and sheds all get in the way. Inside, Colorbond roofs, steel sheds, insulation with foil backing and low-E glass block a lot of what does reach you. The result is familiar: a couple of bars standing by the ute, and dropped calls at the kitchen table or in the office.
The good news is that if your phone works somewhere outside, there is signal to work with. The job is to find the best network, the best spot and the right equipment to bring that signal indoors.
Step 1: test the outdoor signal properly
Bars are not reliable, so measure in dBm. On iPhone you can use the field test mode, and on Android the signal strength figure under the phone's status or SIM settings, or a free signal app. Turn Wi-Fi off, then walk around the house, the sheds and any higher ground. Values closer to zero are stronger: around -80 dBm is good, -100 dBm is weak but usable, and below about -110 dBm calls tend to drop.
Note the reading, the network and whether you see 4G or 5G at each spot. Check the roofline or the top of a ladder if it is safe to do so, because a few metres of height can make a big difference in open country.
Step 2: pick the strongest carrier at your address
Coverage from Telstra, Optus and Vodafone can differ a lot in regional areas. Check each carrier's coverage map for your exact address, then trust real readings over the map. Ask neighbours which network works for them, and consider a prepaid SIM on another network for a week to test it at the house.
If one network is clearly stronger outside, moving to it, or to a provider that uses that network, may be the cheapest fix of all, and it also gives any booster a better signal to start from.
Step 3: try Wi-Fi calling
If you have a reliable internet connection, such as NBN fixed wireless, satellite or a fixed-line service, Wi-Fi calling can route calls and texts over that connection instead of the mobile network. Check whether your carrier supports Wi-Fi calling on your plan and phone, then switch it on in the phone's settings.
Wi-Fi calling helps with calls inside the house, but it does not improve mobile data, and it only works where your Wi-Fi reaches. For sheds, offices and visitors on other networks, a booster is often the better all-round answer.
Step 4: place the external antenna in the right spot
The external antenna is the most important part of the install. Mount it at the spot where you measured the strongest, steadiest reading, as high as practical, on a pole, gable or chimney bracket, and point it towards the tower. Keep it clear of trees, water tanks and large metal surfaces.
Keep plenty of distance between the outdoor and indoor antennas, ideally with the roof between them, to avoid feedback. Use the shortest practical cable run, seal any entry point against water and dust, and fit a surge protector on exposed rural installs. If outdoor signal is only two or three bars, a directional Yagi antenna aimed at the tower usually gives better results than a standard panel antenna.
Step 5: choose the right kit size
Size the kit to the floor area you want covered, not the size of the block. Our Universal kits list 700, 800, 900, 1800, 2100 and 2600 MHz, so check which band your carrier uses at your property before you choose, which suits households where people use different networks.
A 300 m² kit suits a typical homestead with reasonable outdoor signal. The 500 m² kit is a good fit for larger homes, a house plus an attached office, or weaker outdoor signal. For big sheds, workshops or several buildings, look at the 1,000 m² or 5,000 m² kits, or contact us with your readings. Real coverage depends on outdoor signal, building materials and installation.

Frequently asked questions
Which is best in the bush: Telstra, Optus or Vodafone?
It depends on your address. Check each coverage map, then test real signal outside with a SIM on each network before deciding.
What signal reading do I need for a booster?
Some usable signal outside, ideally around -100 dBm or better at the antenna spot. With no usable signal outside, a booster cannot help.
Does one kit work with all three networks?
Our Universal kits list 700, 800, 900, 1800, 2100 and 2600 MHz; check which band your carrier uses at your property before you choose. Send us your readings if you want your bands checked.
Where should the outdoor antenna go?
At the strongest spot you measured, as high as practical, pointed towards the tower and well away from the indoor antenna.
Can I return the kit if it does not work?
We offer 30-day returns. Send us photos or videos of the install first so we can help troubleshoot.
