Hosted PBX Phone Systems for Australian Businesses
A Hosted PBX gives your business a full-featured, professionally managed phone system without the cost or complexity of on-premises hardware. Your provider hosts and manages the system — you simply connect and use it.

What is a Hosted PBX?
A Hosted PBX (Private Branch Exchange) is a business phone system where the PBX — the central switching system that manages your calls — is hosted and operated by a third-party provider at their facility, rather than installed on your premises. Your business connects to it via the internet or a dedicated data connection, accessing the full feature set of a PBX without owning or maintaining any of the underlying hardware.
Hosted PBX is closely related to Cloud PBX — both describe off-premises PBX delivery. The distinction is largely generational: traditional Hosted PBX often referred to legacy PBX hardware hosted in a data centre, while Cloud PBX describes modern software-native systems. Most providers today use the terms interchangeably.
The PBX is hosted by your provider — no server room, no hardware to purchase or maintain, no IT resources required to keep the system running.
Auto attendant, hunt groups, call queuing, call recording, voicemail, conferencing and advanced routing — all delivered as a hosted service without enterprise hardware costs.
System maintenance, software updates, security patches and infrastructure management are all handled by your hosted PBX provider — not your internal IT team.
Connect multiple office locations, remote workers and mobile staff on a single unified phone system — with seamless internal extensions and consistent call handling rules across all sites.
Hosted PBX is typically priced per user per month — converting what would be a capital expenditure into an operating expense with no surprise maintenance costs.
Add users, extensions or features through your provider portal without hardware changes — suited to growing businesses or those with variable headcount.
Who Should Consider a Hosted PBX?
- Businesses replacing ageing on-premises PBX: The end of PSTN infrastructure in Australia and the cost of maintaining legacy PBX hardware are both strong triggers for migration to a hosted solution.
- Multi-site businesses: A single Hosted PBX connects all locations on one system — simpler to manage and more cost-effective than separate phone systems at each site.
- Businesses with remote or hybrid workers: Hosted PBX works from any internet-connected device, making it ideal for teams split across office and home environments.
- Growing businesses: No hardware investment means you can add users as you grow without lead times or capital approval processes.
- Businesses without internal IT: Provider-managed infrastructure removes the burden of PBX maintenance from your team entirely.
With Telstra progressively retiring copper network infrastructure across Australia, businesses still operating on traditional on-premises PBX systems connected via PSTN lines should plan their migration. Contact a Hosted PBX supplier below for migration advice specific to your situation.
