What is a Network Engineer

A Network Engineer builds and manages the computer networks that connect people, devices and data across a business. If you love technical puzzles, this is a great path. You will work at the heart of digital systems, keeping data flowing and networks secure.

Every day looks different. You might set up a wireless system in the morning and track down a fault in the afternoon. You set up routers and switches, watch network traffic and put security measures in place to keep data safe.

Network Engineers work with IT teams, security staff and business managers to keep the network doing its job. Good communication matters just as much as technical know-how.

Demand for Network Engineers in Australia is strong and growing. Salaries start around $80,000 for entry-level roles and average about $120,000 a year (yourcareer.gov.au, 2025). Senior engineers and specialists can earn well above that.

Steps to become a Network Engineer

Step 1: Complete a relevant IT qualification

Most employers want a bachelor degree in IT, computer science or a related field. Common options include a Bachelor of Information Technology or Bachelor of Computer Science. These run for three years at universities across Australia. If you prefer a VET pathway, try the Diploma of Information Technology (Advanced Networking) ICT50220. It takes around 12 to 18 months full-time at a TAFE or RTO. Both pathways cover network design, security, routing and switching.

Step 2: Build hands-on experience in IT support or networking

Look for entry-level roles in IT helpdesk, technical support or junior network admin. Many employers value real-world experience as much as formal qualifications. Internships, part-time roles and volunteer IT work all count. Aim to spend at least 12 months in a support role before moving into network engineering work.

Step 3: Earn your first networking certification

Get your Cisco Certified Network Associate (CCNA) certification. This is the most widely recognised entry-level networking credential in Australia. Study takes around 3 to 6 months using online resources, self-study guides or structured courses. CompTIA Network+ is another solid starting point if you want a vendor-neutral option first.

Step 4: Choose a specialist area and pursue advanced certifications

As you gain experience, choose a focus: network security, cloud networking, wireless systems or large-scale networks. Relevant advanced certifications include the Cisco Certified Network Professional (CCNP). For cloud networking, consider the AWS Certified Advanced Networking or the Microsoft Certified: Azure Network Engineer Associate. These typically take 6 to 12 months of study beyond the CCNA level.

Step 5: Join a professional association and keep learning

Become a member of the Australian Computer Society (ACS). Membership gives you access to professional development events, peer networks and CPD resources. Staying current with new technologies like SDN and zero-trust security is key to career growth. These skills open the door to senior engineer and architect roles.

What does a Network Engineer do?

As a Network Engineer, your day is full of hands-on problem-solving. You design and build networks, set up routers and switches, and watch traffic to keep things running smoothly. If something breaks, you track it down and fix it. You also put security measures in place to keep data safe. Much of the job is team-based. You work with IT teams, security staff and business managers to make sure the network does what the business needs.

Tasks

Network Engineers keep businesses connected, secure and productive. From building new network systems to tracking down faults, the work is varied and hands-on. Here is what a typical week might look like.

  • Network Design: Planning network systems to meet the needs of the business.
  • Installation and Configuration: Setting up hardware and software to build network connections.
  • Network Monitoring: Using tools to track traffic and performance and spot issues early.
  • Troubleshooting: Finding and fixing network problems to keep downtime to a minimum.
  • Security Management: Setting up access controls and protections against cyber threats.
  • Documentation: Keeping accurate records of network layouts, settings and changes.
  • Collaboration: Working with IT and business teams to integrate network solutions.
  • Systems Upgrading: Rolling out new technologies to improve speed and reliability.

Skills for Success

To thrive as a Network Engineer, you need a good mix of tech skills and people skills. You should understand networking protocols, routing and switching, and how to set up firewalls and VPNs. Knowing how to use network monitoring tools and work with cloud systems will also put you ahead.

Strong problem-solving is a must, since no two network faults are the same. You will also need to explain technical issues clearly to teammates and managers who may not have a technical background. The best Network Engineers stay curious, keep learning and adapt quickly when new technology arrives.
