Southern Phone Broadband Plans Review

Southern Phone started in 2002 as a not-for-profit telco serving regional and rural Australia. The Moruya-based company, owned by 15 local councils in southern NSW, sells NBN broadband, mobile plans, and home phone services. Revenue goes back into regional telecommunications projects instead of shareholder dividends.

Southern Phone competes with Telstra, Optus, Aussie Broadband, and Superloop on the NBN. The company markets itself on Australian-based customer support and straightforward plan structures. You can sign up from anywhere in Australia with NBN access, not from regional areas alone. The council ownership structure gives Southern Phone a unique position in the market: it operates like a commercial telco but reinvests profits into rural connectivity.

Southern Phone offers NBN plans across four speed tiers: NBN 25, NBN 50, NBN 100, and NBN 250. All plans run month-to-month with no lock-in contracts. The company includes a modem for $0 upfront on a 24-month agreement, or you can BYO a compatible router. If you take the included modem and leave before 24 months, Southern Phone charges an early termination fee proportional to the remaining months.

These prices sit in the mid-range of the Australian NBN market. Aussie Broadband charges $79/month for NBN 50, while Superloop undercuts at $69/month for the same tier. Southern Phone's $70 for NBN 50 lands between those two. The gap widens at higher tiers: TPG sells NBN 100 at $85/month versus Southern Phone's $90.

Southern Phone does not charge setup fees for standard NBN connections. If your address needs new NBN infrastructure (common in rural fixed wireless areas), NBN Co handles the installation at no cost for standard installs. Non-standard installations, such as those requiring trenching or extended conduit runs, may incur charges from NBN Co that Southern Phone passes through.

Southern Phone does not offer introductory or promotional pricing. The price you see when you sign up is the price you pay in month 12 and month 24. This contrasts with Tangerine Telecom and Spintel, which advertise low introductory rates that increase after six months. Customers who dislike price surprises will appreciate Southern Phone's flat pricing model.

Southern Phone purchases bandwidth from NBN Co through a wholesale arrangement called CVC (Connectivity Virtual Circuit). Every NBN retailer shares CVC capacity among its customers. The ACCC's Measuring Broadband Australia (MBA) program tests ISP speeds during the 7pm to 11pm evening peak. Southern Phone has appeared in MBA reports with typical evening speeds that track close to advertised rates, though the company does not feature in every quarterly report due to sample size limitations in the testing panel.

On NBN 50, Southern Phone advertises a typical evening speed of 45 Mbps. That number holds up for fibre-to-the-premises (FTTP) and fibre-to-the-node (FTTN) connections in areas with short copper lead-ins. FTTN connections with copper runs over 400 metres may not reach 50 Mbps at any time of day. This is an NBN infrastructure limitation, not a Southern Phone issue. You can check your connection type and line length through the NBN Co website by entering your address.

Fixed wireless NBN customers in regional areas should expect lower speeds. NBN fixed wireless delivers 25 to 75 Mbps depending on tower congestion and distance from the tower. Southern Phone sells NBN 25 and NBN 50 plans on fixed wireless. The company does not sell NBN 100 or NBN 250 on fixed wireless because the technology cannot sustain those speeds. Peak-hour congestion on popular fixed wireless towers can drag speeds below 20 Mbps. NBN Co has been upgrading fixed wireless towers to 5G technology since 2023, which improves capacity, but coverage remains patchy.

Upload speeds on Southern Phone plans follow NBN wholesale defaults. NBN 50 includes 20 Mbps upload. NBN 100 includes 20 Mbps upload unless you select a plan with 40 Mbps upload (Southern Phone offers this as an option at a higher price). Households with multiple people video-calling or uploading large files to cloud storage should check the upload speed before committing to a plan.

For gamers, Southern Phone does not advertise gaming-specific features like low-ping routing or dedicated gaming servers. Latency on FTTP and FTTC connections sits between 8ms and 15ms, which is standard across all NBN retailers. If you play competitive online games, your connection type matters more than your ISP. FTTP delivers the lowest and most consistent latency. HFC and FTTN add variability during peak hours.

Southern Phone runs its call centre from Moruya on the NSW South Coast. The company employs Australian-based support staff and does not outsource calls overseas. This matters to customers who have dealt with offshore call centres at Telstra, Optus, or TPG and found the experience frustrating. The Moruya team answers calls, handles fault reporting, and processes plan changes.

Phone support operates Monday to Friday, 8am to 8pm AEST, and Saturday 9am to 5pm. No Sunday support. The company also offers online chat and email support through its website. Email responses take 24 to 48 hours during busy periods. Complaints go through a standard internal dispute process, with the Telecommunications Industry Ombudsman (TIO) available as an escalation point if the internal process fails to resolve the issue.

TIO complaint data from 2024/2025 shows Southern Phone receives fewer complaints per customer than Telstra, Optus, and Vodafone. Smaller ISPs tend to generate fewer TIO complaints, partly because their customer bases skew toward less price-sensitive users who stay longer. The low complaint rate also reflects Southern Phone's simpler product range: fewer add-ons and bundles means fewer billing disputes.

One gap in Southern Phone's support: the company does not offer a mobile app for account management. You manage your account through the website portal. Aussie Broadband and Telstra both offer apps that let you check usage, run speed tests, and contact support. If app-based management matters to you, this is a drawback.

Southern Phone sells mobile plans alongside broadband. Mobile plans use the Optus 4G/5G network, giving reasonable regional coverage in eastern Australia. Plans range from $15/month for 4GB to $45/month for 40GB data. All mobile plans run month-to-month. Bundling mobile and broadband does not unlock any discount. The company prices each service independently.

The Optus network suits eastern-seaboard regional areas. Customers in western NSW, outback Queensland, or remote Western Australia will find gaps in Optus coverage. Telstra's network reaches further into rural Australia. If mobile coverage is critical to your location, check the Optus coverage map for your address before signing up to a Southern Phone mobile plan.

Home phone service over NBN costs $10/month as an add-on to any broadband plan. Southern Phone includes unlimited local and national calls in the home phone add-on. International calls cost extra on a per-minute basis. If you use a home phone line for medical alarms or security systems, confirm compatibility with NBN voice before signing up. NBN voice services drop out during power outages unless you have a battery backup unit connected to your NBN equipment.

Southern Phone does not offer NBN enterprise or business-grade plans. Small business owners who need static IP addresses, enhanced SLAs, or priority fault restoration should look at Aussie Broadband's business plans or Telstra's Enterprise Ethernet product. Southern Phone's residential plans work for home offices and sole traders with standard connectivity needs.

Southern Phone works well for customers who value Australian-based support over the lowest possible price. The company charges $5 to $10 more per month than budget ISPs like Spintel and Tangerine on equivalent speed tiers. You pay that premium for local call centre staff, a not-for-profit structure, and consistent pricing without promotional jumps.

Regional customers on NBN fixed wireless benefit from Southern Phone's familiarity with rural connectivity issues. The support team handles fixed wireless troubleshooting without defaulting to scripts written for metropolitan fibre connections. Staff in Moruya understand that a customer in Bega or Merimbula faces different internet conditions than someone in Surry Hills. While reviewing your internet, also compare electricity rates in your state to reduce other household bills.

If price drives your decision above everything else, Superloop ($69/month for NBN 50) or Spintel ($59/month for NBN 50) will save you $120 to $130 per year over Southern Phone. Those ISPs also deliver competitive speeds. The trade-off lands on support quality and call centre location. Our guide on how to switch NBN providers covers the transfer process step by step.

Southern Phone delivers a solid mid-range NBN product with Australian support. You will not find the cheapest plans here. You will find reliable speeds, no lock-in contracts, and a support team that picks up the phone in Moruya. The not-for-profit structure means your monthly payment funds regional telecom infrastructure rather than shareholder returns.

For regional households on fixed wireless who want an ISP that understands rural Australia, Southern Phone earns a recommendation. The company's roots in regional council ownership give it a perspective that metro-focused ISPs lack. Metro customers chasing the lowest dollar amount should compare Superloop and Spintel first, then weigh whether the support difference matters enough to pay $5 to $10 more per month.

Households spending over $80/month should also consider Aussie Broadband. Aussie Broadband matches Southern Phone's Australian support commitment, offers a mobile app, and participates in ACCC speed monitoring with transparent results. At the NBN 100 tier, Aussie Broadband's pricing and feature set make it a strong competitor to Southern Phone's Premium plan.
