Southern Phone broadband | ADSL and NBN plans

Providing NBN, ADSL, mobile voice and mobile broadband services, Southern Phone Broadband can offer you a deal with the lot.


Southern Phone Broadband is a Moruya-based Internet provider focused on supplying NBN, ADSL and mobile services across Australia. It offers broadband via all the standard NBN access technologies excluding HFC cable. With a choice of contract lengths, there are also the options to sign up for a copper or VoIP phone line and even add in Southern Phone's mobile service in a "triple bundle".

Southern Phone NBN plans

Southern Phone Broadband's NBN plans support most standard NBN access technologies: fibre to the premises (FTTP), fibre to the node (FTTN), fibre to the building (FTTB), fixed wireless and satellite but not hybrid-fibre coaxial (HFC).

Depending on the technology, all four main NBN speed tiers are available: Basic (nbn12), Standard (nbn25), Standard Plus (nbn50) and Premium (nbn100). As for data allowances, Southern Phone Broadband's range of NBN plans vary from 100GB p/m (or 70GB p/m on satellite) up to unlimited data. Satellite aside, on a Basic 12Mbps connection this gives you a choice between the following five plans:

  • Small, which includes 100GB of data for $45 a month
  • Medium, which includes 200GB of data for $50 a month
  • Large, which includes 500GB of data for $55 a month
  • X-Large, which includes 1000GB of data for $60 a month
  • XX-Large, which includes unlimited of data for $65 a month

Boosting your download speed to Standard will cost you an extra $10 p/m, while upgrading to a Standard Plus connection will set you back an extra $20 p/m. A Premium connection will cost you an additional $30 p/m. The only exception to this is the XX-Large unlimited plans which are only available at Basic and Standard speeds.

While the monthly pricing is identical regardless of contract length – 1, 12 or 24 months – the initial set-up fees are not. On a month-to-month contract, you'll need to pay an upfront fee of $200, but this drops to $100 on a 12-month contract or $0 on a 24-month contract.

As you'd expect, there are penalties for breaking your contract. Under a 24-month deal, the Early Termination Fee (ETF) is $20 multiplied by the number of months remaining on the contract. Under a 12-month deal, the ETF for cancellation at any time within the contract term is $50.

A Wi-Fi modem and delivery is included with a 24-month contract. You can purchase a NetComm Wi-Fi router from Southern Phone Broadband or bring your own.

At least you won't have to worry about any excess data charges with Southern Phone Broadband, although the throttling is rather brutal. Going over your monthly data cap will see your speed slowed to a draconian 64kbps for the rest of the current billing cycle, whereas more providers throttle you to 256kbps.

Southern Phone ADSL plans

Southern Phone Broadband offers a choice of download limits on ADSL, although confusingly the tiers offer different data allowances to its NBN plans.

  • Small, which includes 200GB of data for $50 per month
  • Medium, which includes 500GB of data for $60 per month
  • Large, which includes 1000GB of data for $70 per month
  • Unlimited, which includes unlimited data for $80 per month

Like its NBN plans, Southern Phone Broadband's ADSL plans are available on a month-to-month, 12 or 24-month contract.

On a month-to-month contract, you'll need to pay an upfront fee of $200, but this drops to $100 on a 12-month contract or $0 on a 24-month contract. There are penalties for breaking your contract. Under a 24-month contract, the Early Termination Fee (ETF) is $20 multiplied by the number of months remaining on the contract. Under a 12-month contract, the ETF for cancellation at any time within the contract term is $50.

A NetComm NF10WV Wi-Fi router modem and delivery is included with a 24-month contract, otherwise you can upgrade to a NetComm NF18ACV Wi-Fi router for $149 unless you intend to bring your own.

Things become more complicated if you want to bundle a home phone line, with a choice of a standard copper line or a VoIP service. There are also "triple bundles" which add a mobile phone service. If you're looking at a bundle, keep in mind that the data allowances differ from those above and start at a lowly 50GB p/m.

Southern Phone mobile broadband plans

Along with mobile voice services, Southern Phone Broadband also offers data-only mobile broadband services with a choice of using Telstra or Optus' 3G/4G mobile network – labelled "Orange" and "Green" plans respectively.

As you'd expect, the Optus deals offer better value for money but Telstra tends to provide wider coverage, so it pays to do your homework before signing up, especially if you live outside the major cities or in a known metro black spot.

Optus deals range from $22 p/m for 8GB to $85 p/m for 90GB. Meanwhile, Telstra deals range from $30 p/m for 5GB to $85 p/m for 30GB. All plans are on 12-month contracts, but the fine print varies depending on the network provider.

With Optus, if you exceed your monthly data allowance you'll be automatically charged $10 for each addition 1GB, up to a maximum of 3GB over your cap in one month. After that you're charged 15 cents per MB, which works out as a hefty $150 per GB. There is also a $10 p/m early termination fee.

With Telstra there are no $10 data boosts. Instead, if you exceed your monthly data allowance then you're immediately slugged 15 cents per MB of usage. On the upside, there's no early termination fee if you break your contract.

With either telco you can purchase a mobile Wi-Fi hotspot outright for $99, or else just take a SIM card and bring your own hotspot.

It's worth noting that data-only mobile broadband services aren't included in the "triple bundle" service, only mobile voice/data services.

Southern Phone extras

If you don't have a compatible modem-router, an NBN connection isn't going to do you much good. Thankfully, Southern Phone Broadband offers the NetComm NF10WV Wi-Fi router modem – included with a 24-month contract – or you can upgrade to a NetComm NF18ACV Wi-Fi router which offers AC1600 wireless speeds and supports both the 2.4GHz and 5GHz bands.

Southern Phone Broadband also offers the option of a Voice over IP (VoIP) phone service alongside its NBN plans or standard phone service alongside its ADSL plans.

The bundles include the $10 p/m Medium voice deal which offers unlimited local and national calls along with 37c/min calls to mobiles. You can vary this by mixing and matching your own broadband and voice services rather than choosing from the pre-configured bundles.

Southern Phone Broadband also offers "Home Plus" bundles which include a home phone and mobile voice service. You can also opt for a "triple bundle" which includes NBN (12-month contract) or ADSL (24-month) broadband, a home phone line and mobile phone service. Once again, these pre-configured triple bundles don't offer every plan permutation so you might prefer to shop a la carte.

How does Southern Phone Broadband compare?

As with most Internet providers, Southern Phone Broadband keeps its monthly pricing consistent regardless of contract length and only changes the set-up fees. The below comparisons are all based on its more flexible month-to-month plans, but keep in mind that Southern Phone Broadband's data allowances can vary if you sign up for a bundle. Also remember that the compared plans may or may not include a phone service and set-up fees.


How do Southern Phone's fixed line NBN plans compare?

Not all providers offer allowances as low as 100GB per month, but if you're determined to opt for this low data allowance then Southern Phone Broadband's Small plan stacks up reasonably well. There are better deals around, however. You can save a few dollars elsewhere, or even double your data allowance from Teleron for the same price. Keep in mind all these rivals might not offer the convenience of double and triple bundles for keeping all your communications spend on the one bill.


Once you step up to unlimited plans Southern Phone Broadband's Unlimited plan falls far behind the competition in terms of value for money.


Southern Phone Broadband is generally on par with its rivals when it comes to opting for faster download speeds – offering the flexibility of all four NBN speed tiers. It's the data allowances which hamper its value for money, especially when you can't opt for unlimited downloads at Standard Plus or Premium speeds.

How do Southern Phone Broadband's fixed wireless NBN plans compare?

Thankfully, Southern Phone Broadband's fixed wireless NBN pricing and data allowances are the same as its fixed line NBN services, although depending on your location, you might not have access to all the speed tiers.

As such, its fixed wireless plans stack up against its rivals much the same as its fixed line plans. Things change at the faster tiers, as not all providers offer fixed wireless above Standard speeds but Southern Phone Broadband goes as high as Standard Plus.


If you only want 100GB per month then Southern Phone Broadband doesn't look too bad, but the picture gets worse as you dial up the data allowance – with Southern Phone Broadband's Unlimited plan falling behind the competition.

How do Southern Phone Broadband's phone packs compare?

This is where Southern Phone Broadband's bundling situation gets complicated. On the NBN, its VoIP bundles add $10 to the cost each month, but you only have a choice of 100GB, 200GB or unlimited plans. Not all speed tiers are visible until you enter your address and go to purchase a plan, keeping in mind that unlimited plans aren't available at the Standard Plus and Premium speed tiers.

These bundles entitle you to Southern Phone Broadband's Medium VoIP plan (see below). Alternatively you can sign up for an NBN and VoIP plan separately which gives you the choice of the following VoIP plans:

  • Small $5 p/m - 10c local, 25c/min national, 37c/min mobile
  • Medium $10 p/m - unlimited local, unlimited national, 37c/min mobile
  • Large $20 p/m - unlimited local, unlimited national, unlimited mobile
  • XL International $40 p/m - unlimited local, unlimited national, unlimited mobile, unlimited landline calls to some countries

On ADSL, bundles include a copper phone line service and require a 24-month contract. They come with a choice of 50GB for $70 p/m – offering the same call rates as the Medium VoIP plan – or else 200GB ($80 p/m) or unlimited data ($90 p/m) which offer the same call rates as the Large VoIP plan.

On top of this, Southern Phone Broadband also offers "triple bundles" which include broadband, a home phone line and mobile phone service. Below compares Southern Phone Broadband's NBN VoIP call packs with the competition.

How do Southern Phone Broadband's ADSL plans compare?

Southern Phone's ADSL plans start at a reasonably competitive price, but other providers still manage to undercut it. The plans become less competitive as you work up to the unlimited tier, and keep in mind that some providers might include a phone service in these prices, plus ADSL deals can vary between metro and country areas.

How do Southern Phone Broadband's mobile broadband plans compare?

Southern Phone's choice of using Optus or Telstra's mobile networks offers the best of both worlds – letting your save money if you're within range of the Optus network but offering the breadth of the Telstra footprint if you really need it.

At the budget end, getting 8GB for $22 per month on Optus is a great deal. Most telcos only offer 5GB at these prices, though Bendigo Telco currently undercuts Southern Phone thanks to its 3GB bonus offer on its 5GB plans.


As you increase your monthly data allowance, Southern Phone's Optus deals remain very competitive. A few telcos like Lebara Mobile and Kogan Mobile, which resell Vodafone's mobile broadband, slightly beat out Southern Phone with their 25GB plans.


Once you hit the 100GB mark, Optus resellers OVO and amaysim sneak ahead in terms of value.
