CompTIA Network+ (N10-009) is the vendor-neutral certification that validates the networking knowledge required for network administrator, network support, and cloud networking roles in Australia. It is the logical progression after CompTIA A+ for IT support professionals building toward more specialised technology careers — particularly cloud computing, cybersecurity, and systems administration.
Network+ covers TCP/IP in depth, wireless networking, network security, troubleshooting methodology, and the networking concepts underlying cloud and virtualisation platforms. It is a single exam (unlike A+'s two) and sits at the intersection of IT support and infrastructure roles.
IT support professionals with A+ or equivalent experience who want to move into networking or infrastructure roles. Career changers with a technical background in telecommunications or broadband support who want formal certification. Anyone targeting Network Administrator, Junior Network Engineer, or Cloud Support roles in Australian ISPs, telecommunications companies, managed service providers, or large enterprise IT teams.
Network models — OSI and TCP/IP layers in practical troubleshooting context. IP addressing — subnetting (IPv4 and IPv6), CIDR notation. Switching — VLANs, STP, port security. Routing — static routing, OSPF, BGP basics. Wireless networking — 802.11 standards, WPA3, site surveys. Network security — firewalls, IDS/IPS, VPNs, NAC. Cloud and virtualisation networking. Network monitoring and troubleshooting tools — Wireshark, ping, traceroute, nslookup. Documentation and network diagrams.
Network Administrators in Australia earn $80,000–$110,000 AUD. Network Engineers earn $100,000–$140,000 AUD. Network+ is also a formal prerequisite for several advanced networking certifications including CCNA, which opens even higher-paid infrastructure roles.
Exam fee: approximately USD $358 (~$545 AUD). Free study: Professor Messer's free Network+ course (YouTube). Udemy practice exam: $15–$25 AUD on sale. Total cost: approximately $565–$580 AUD. Study time: six to twelve weeks at five to eight hours per week.
Pros: Vendor-neutral — applies across Cisco, Juniper, and cloud networking environments. Clear pathway to CCNA and cloud networking certifications. Single exam unlike A+. Cons: Subnetting is genuinely challenging for people with no networking background — dedicate real time to this topic.
Do I need A+ before Network+? CompTIA recommends A+ first but does not require it. If you already have solid IT or networking experience, you can go directly to Network+. If you are a complete beginner, do A+ first.
