Sharehouse NBN in Australia (2026): How to Pick the Plan, Split the Bill, and Stop the Bandwidth Hog

Last updated: 20 May 2026

Sharehouse internet has its own set of problems and nobody writes guides for them. The “best NBN plans” articles assume one person on the connection. Sharehouse internet is four or five people who don’t share a credit card, don’t all stream Netflix on the same account, can’t agree on whose name goes on the bill, and have at least one housemate who runs torrents at 11pm. The plan you pick matters less than how you set the connection up — and almost nobody covers that part.

This article walks the five specific problems sharehouses run into with their internet, with concrete fixes for each. Treat it as a diagnostic guide, not a “best plans” list — the right plan falls out of the right setup.

Problem #1 — Whose name goes on the bill?

Only one person can be the account holder for a residential NBN connection. That person is liable for the entire bill, gets the credit check, and has to chase housemates for payment if they leave the country with two months unpaid. It’s not a small risk — a $99/month plan abandoned by a housemate who’s flown to Bali becomes $1,200 chasing them through a debt collector.

The fix

Two real options. Option one — the longest tenured housemate takes the account, with explicit written agreement (a paragraph in your sharehouse group chat is enough) that the others pay their share by the 1st of every month, and that if anyone moves out they pay through to the end of that calendar month. Option two — sign up to a no-lock-in plan in the name of the housemate most likely to stay longest. Aussie Broadband, Superloop, MATE, Tangerine, and Belong are all month-to-month with no exit fees, so if the situation deteriorates the account-holder can cut the plan and the others can re-sign in their own name.

What not to do: don’t put it in the name of the housemate moving out in three months. Don’t open multiple accounts at the same address — it’s not possible on the same NBN service ID. Don’t pretend the bill belongs to “the house” with no human named.

Problem #2 — How do we split the bill fairly?

The fix

The three options above. Even split is the default, fairest in most cases, and the easiest to administer — Splitwise handles it in two taps. Take this unless someone in the house is using the connection clearly differently from everyone else.

The heavy-user surcharge is for the housemate running a video-editing business from their room, twitch-streaming all night, or downloading 50GB game updates weekly. They pay $10 to $15 more, the rest is split among everyone else. Have the conversation early — once a sharehouse has a “the heavy user pays more” rule, it stops being awkward.

The by bedroom size split applies if your rent is already split unevenly (master bedroom pays more, the small room pays less). Mirror that split for the internet. It feels weird at first but it’s actually the most defensible — everyone pays in proportion to what they pay for the house overall.

Tools that work: Splitwise (free, every sharehouse knows it), Beem (faster transfers, more visual), or a simple shared Google Sheet. Whatever you pick, set a calendar reminder for the 1st of each month — payment delay is the second-biggest cause of sharehouse internet drama.

Problem #3 — Someone is hogging all the bandwidth

This is the most common sharehouse internet complaint. At 8pm one housemate is downloading the new Call of Duty patch (180GB), one is streaming Netflix in 4K, and your Zoom call is frozen. The NBN plan tier matters less than the router’s ability to share bandwidth fairly across active users.

The fix

Turn on QoS (Quality of Service) on the router. Every router from 2020 onwards has it under a menu typically labelled QoS, Traffic Manager, or Bandwidth Control. The setup is three tiers as in the diagram above — high-priority devices always get bandwidth first, medium-priority devices get what’s left, low-priority background traffic is throttled to spare capacity only.

Specific router menus:

The second fix: get a router that can actually handle four to six people at once. The ISP-supplied modem is usually fine for a couple. For a sharehouse, a Wi-Fi 6 router (TP-Link AX3000 around $180, ASUS RT-AX86U around $300, or a two-node mesh kit at $250) handles concurrent devices far better than the default modem. Our BYO modem setup guide walks through the shortlist.

The third fix is the social one: a sharehouse rule that large downloads (game patches, OS updates, cloud backups) run after midnight. Schedule them in the app. It costs nothing and solves 80% of the bandwidth hog cases.

Problem #4 — Wi-Fi doesn’t reach the back bedrooms

Sharehouses tend to be older buildings, which means thick brick walls, longer floor plans, and the modem ending up in whatever room the NBN box happens to be in — usually the front lounge, sometimes a hallway cupboard. Result: the housemate in the back bedroom gets garbage Wi-Fi.

The fix

In order of cost and effort:

• Move the router 3 metres closer to the centre of the house. A long Ethernet cable from the NBN box to a more central spot costs $20. Try this first.
• A two-node mesh kit ($150 to $300) — one node where the existing router is, one in the hallway. Covers most sharehouses end-to-end.
• Ethernet drops to specific rooms if you’re going to be in the place for years and you have someone in the house who’s confident running cable. Each housemate plugs in directly to their bedroom and Wi-Fi becomes the secondary connection.
• Don’t use Wi-Fi extenders. They halve your speed and they make the situation worse for everyone except the immediate user. Skip.

Cost-sharing tip — if the mesh kit benefits the whole house, split it across all housemates the same way as the monthly bill. $250 across four housemates is $62.50 each, one-off.

Problem #5 — A housemate moves out, takes the account with them

The least obvious sharehouse problem, but the one that causes the most chaos. The housemate whose name was on the NBN account moves out, cancels the plan on their way out the door, and the rest of the house has no internet on day one of the new month.

The fix

Two parts. First, transfer the account before they leave — most retailers do this in a single phone call: the old housemate calls, says “I’m leaving the address, my housemate is taking over the account, can you transfer it.” The new housemate’s credit check happens, the plan transfers, no service interruption. Aussie Broadband, Superloop, MATE, and Tangerine all do this routinely. Telstra and Optus do it but take longer and may require both housemates on the same call.

Second, if a transfer falls through, a brand-new plan from a different no-lock-in retailer can usually activate within 1-2 business days because the connection already exists at the address. There’s a small risk of a service gap; 5G home wireless from Optus or TPG is the standard bridge — $79/month month-to-month, plug-and-play modem.

The sharehouse switching guide is at our how to switch NBN providers piece. The steps are the same as a normal switch, just with a transfer-of-name added.

The right plan for a sharehouse

Once you’ve got the setup right, the plan is the easy part. For 3 to 4 housemates, NBN 100 from Aussie Broadband, Superloop, MATE, or Tangerine — all month-to-month, all with honest evening speeds, all under $100 per month. For 5+ housemates or a house with a heavy user, jump to NBN 250. NBN 50 only works for sharehouses where most people are out during the day and Wi-Fi use is mostly nights and weekends.

A short glossary for sharehouse internet

• Account holder — the housemate whose name is on the NBN bill. Liable for the whole bill until the account is transferred or cancelled.
• QoS (Quality of Service) — router setting that prioritises certain devices’ traffic in peak hour. The fix for the bandwidth-hog problem.
• No lock-in — month-to-month plan with no exit fees. Essential for sharehouses because the housemate composition will change.
• Mesh kit — two or three Wi-Fi units that work together to cover a large house with consistent Wi-Fi. Different from a Wi-Fi extender, which only repeats one signal.
• Splitwise / Beem — apps that handle the monthly bill split. Free, used by every sharehouse in Australia.
• Account transfer — moving the NBN account from one housemate’s name to another’s without disconnecting service. Usually free, one phone call.

Run a speed test if your sharehouse internet feels slow

Before you change retailers or upgrade plans, run a speed test on the connection at 8pm on a weeknight. That’s when all four housemates are home and the network is most loaded. The result tells you whether the problem is the plan tier, the retailer, or the router — and the fix is different for each.
