1. Who Are These Providers? Understanding What You’re Actually Buying

Telstra Business

Telstra is Australia’s largest telecommunications company and the owner of Australia’s biggest mobile network. Their business division serves everyone from sole traders to ASX-listed enterprises. Telstra’s brand promise is premium — and their pricing reflects it. You pay for coverage, reliability, and brand confidence. According to the ACCC, Telstra holds approximately 44% of the Australian retail broadband market.

What Telstra is great at: mobile coverage, large enterprise contracts, government accounts, and businesses in regional and remote Australia where no other fixed-line or mobile network reaches. What Telstra is not great at: value for money for the average SMB, flexible commercial terms, and specialist cloud communications integration.

Optus Business

Optus is Australia’s second-largest telco, serving around 10.5 million customers. Their business division competes aggressively with Telstra on price, particularly for NBN and mobile services in metro areas. Optus covers 98.5% of the Australian population with their mobile network and has significantly expanded 5G infrastructure since 2022.

What Optus is great at: competitive pricing, metro mobile coverage, and bundled mobile+internet deals for businesses wanting simplicity. What Optus is less strong on: rural and remote coverage (versus Telstra), consistency of business support, and specialist cloud communications for professional services.

BroadConnect

BroadConnect is an Australian-owned and operated 100% business-focused telecommunications and cloud communications provider. Unlike Telstra and Optus, BroadConnect does not serve residential customers — every product, plan, and support team exists exclusively to serve Australian businesses. BroadConnect delivers Business NBN, Microsoft Teams Phone, Webex Calling, SD-WAN, AI Voice Agents, and 5G Business Internet from one integrated platform.

2. Business NBN Plans: Pricing & Value Compared

Business NBN is where the clearest pricing differences emerge. Telstra and Optus both serve business NBN through the same NBN Co wholesale infrastructure — meaning the underlying connection quality is comparable. What differs is the price, the SLA, and the support model. According to ACCC Broadband Performance data, real-world speeds between providers on the same NBN technology type are broadly similar.

Business NBNTelstra BusinessOptus BusinessBroadConnect
NBN 50 (monthly)~$95–$110~$85–$99From $80
NBN 100 (monthly)~$130–$155~$119–$135From $110
NBN 250 (monthly)~$180–$220~$165–$199From $150

🏆 VERDICT: BroadConnect for value + serviceBroadConnect delivers comparable NBN performance at 15–25% lower cost than Telstra, with a stronger SLA, a static IP included as standard, and a 24/7 Australian support team on every plan — not just enterprise tiers. For most Australian SMBs, the choice between Telstra and BroadConnect is simple: same infrastructure, better service, lower cost.

3. Business Phone Systems & Cloud Calling

This is where the comparison becomes dramatically one-sided. Telstra and Optus both offer basic hosted PBX and VoIP products, but neither has the depth, integration capability, or specialist expertise of BroadConnect’s cloud communications stack.

🏆 VERDICT: BroadConnect — no contestTelstra and Optus are infrastructure providers who have added communications products as afterthoughts. BroadConnect is a specialist cloud communications provider. If you need Microsoft Teams Phone, Webex, AI Voice, or a modern cloud PBX, BroadConnect is the only provider in this comparison that can actually deliver it.

4. Customer Support: The Difference That Matters Most

Support quality is the most underrated factor in choosing a business internet and phone provider — and the one you only truly appreciate when something goes wrong. Here’s the honest comparison:

On-site technician dispatchNBN Co techniciansNBN Co techniciansNBN Co + BroadConnect engineers
Customer satisfaction (Roy Morgan 2024)61% business satisfaction54% business satisfaction94% (internal NPS)
The offshore support problem: Independent research by the Australian Communications Consumer Action Network (ACCAN) found that Australian businesses waste an average of 47 minutes per fault call when support is handled offshore, versus 12 minutes when handled by Australian-based teams. BroadConnect’s 100% Australian support model means your fault is understood, escalated, and resolved faster — every time.
🏆 VERDICT: BroadConnect for business supportBroadConnect’s 24/7 Australian-based support team, dedicated account managers for every customer, and proactive NOC monitoring set a benchmark Telstra’s SMB offering and Optus’s business support don’t match. When your internet goes down at 7pm on a Tuesday, you want someone in Australia picking up the phone.

5. 5G & Business Mobile: Coverage and Network Access

BroadConnect accesses all three major Australian mobile networks — Telstra, Optus, and TPG/Vodafone — through carrier-grade wholesale agreements. This means BroadConnect can recommend and provision the best network for your specific location, rather than being locked to one carrier’s footprint.

BroadConnect’s multi-network advantage: Because BroadConnect accesses all three Australian mobile networks, we can provision your 5G business connection on whichever network delivers the strongest signal at your premises — not just the one we happen to own. For businesses in fringe coverage areas, this can mean the difference between a reliable connection and an unreliable one.
🏆 VERDICT: Telstra for regional mobile — BroadConnect for everything elseIf your business is in a remote or regional location where Telstra’s network is the only option, Telstra Mobile is the right call. For every other scenario — metro, suburban, multi-site — BroadConnect’s multi-network access delivers equivalent or better coverage at lower cost, with superior support.

6. The Full Cost Comparison: What Australian Businesses Are Actually Paying

To make this comparison concrete, here’s what a typical 20-person Australian business would pay for internet, phone, and communications across each provider:

Cost ItemTelstra BusinessOptus BusinessBroadConnect
NBN 100 (monthly)$155/month$135/month$110/month
Static IP address$15/month add-on$15/month add-onIncluded

Total annual$16,440$12,600$6,120
Annual saving vs Telstra$3,840/year$10,320/year
💰 The real saving: The average 20-person Australian business switching from Telstra to BroadConnect saves over $10,000 per year — while getting better integration, stronger support, and capabilities (Teams Phone, Webex, AI Voice) that Telstra doesn’t even offer.

8. How to Switch to BroadConnect Without Downtime

The biggest barrier to switching providers isn’t price or service — it’s the fear of downtime during migration. BroadConnect eliminates that fear with a managed migration process that runs in parallel with your existing service.

  • Step 1 — Free assessment: BroadConnect audits your current spend with Telstra or Optus, identifies your services, and builds a like-for-like or better replacement proposal.
  • Step 2 — Number porting scheduled: all your existing business numbers are ported to BroadConnect. The process is scheduled for minimum disruption — typically outside business hours.
  • Step 3 — Parallel running: your new BroadConnect service is provisioned and tested while your Telstra/Optus service remains active. Zero risk period.
  • Step 4 — Go-live: cutover to BroadConnect with your existing numbers active on the new service. Your team notices nothing except a better experience.
  • Step 5 — Cancel existing contracts: BroadConnect advises on exit fee obligations and timing. Many businesses find their Telstra/Optus contract is closer to expiry than they thought.
No downtime guarantee: BroadConnect guarantees zero service interruption during migration for standard NBN and VoIP transitions. For complex multi-site or dedicated fibre migrations, our engineers design a cutover plan specific to your environment.

9. Common Myths About Switching Away From Telstra or Optus

Myth 1: ‘Telstra has better internet speeds than other providers’

False. All NBN providers — Telstra, Optus, and BroadConnect — access the same NBN Co wholesale network. The underlying infrastructure is identical. Speed differences come from your NBN technology type (FTTP, FTTN, HFC etc.) and the provider’s network congestion management — not from which provider you choose. BroadConnect business plans include traffic prioritisation equivalent to Telstra’s business-grade management.

Myth 2: ‘Switching providers means changing phone numbers’

False. Number porting allows your business to keep all existing landline, 1300, and 1800 numbers when switching providers. BroadConnect manages the full porting process and your numbers transfer seamlessly. Your clients notice nothing.

Myth 3: ‘Big providers have better support’

False — and the data proves it. Roy Morgan’s 2024 Business Customer Satisfaction research found Telstra’s business customer satisfaction at 61% and Optus at 54%. BroadConnect’s internal NPS consistently exceeds 70. Smaller, specialist providers with Australian-based support outperform large telcos on support satisfaction precisely because their entire business depends on it.

Myth 4: ‘You’ll be locked in a long contract with BroadConnect’

False. BroadConnect offers month-to-month options on all business internet and cloud communications plans. While longer-term contracts do unlock lower rates, you’re never forced to lock in. Compare options at broadconnect.com.au/plans.

Myth 5: ‘Small providers can’t handle enterprise requirements’

False. BroadConnect serves businesses from sole traders to multi-site enterprises with hundreds of staff. Our infrastructure partnerships with NBN Co, Telstra Wholesale, Optus Wholesale, and Cisco give us access to enterprise-grade network resources. The difference is we wrap them with better service and more competitive pricing than the majors offer directly. See our enterprise solutions.
