Australian cyber security firm AUCyber has merged with Aussie telco 5G Networks, promising “expanded IT, cloud, and cyber security expertise”.
Australian sovereign cyber security provider AUCyber has announced a merger with telecommunications carrier 5G Networks (5GN), completing a process that began almost 12 months ago.
“We’re excited to share that AUCyber and 5G Networks have officially merged, bringing together two Australian technology leaders with one shared vision: to strengthen how we protect, connect, and empower Australian businesses,” AUCyber said in a 20 October announcement.
The company said the merger would help boost its capacity to support its customers, combining AUCyber’s security expertise with 5GN’s nationwide network of data centres.
“You’ll continue working with the same AUCyber team, now backed by the national scale and infrastructure of 5G Networks,” AUCyber said.
“Together, we’re strengthening how we protect, connect and empower Australian businesses.”
5G Networks’ ownership of AUCyber increased to 90.2 per cent in early September, following the release of AUCyber’s Annual Report the month before. AUCyber noted in a 4 September ASX announcement that 5GN now had six months to “exercise its general compulsory acquisition power” under the Corporations Act.
AUCyber was advised at the time that 5GN’s board had not yet determined that it would exercise its power of acquisition.
Speaking to Cyber Daily about the merger, Ernie Hug - Group Executive, MSP & Information Security Services Sales - said the move provides a "powerful new dimension for AUCyber customers".
"It will provide deep managed IT capability complimenting the sovereign cybersecurity portfolio enabling us to deliver secure, scalable infrastructure and end-to-end support across Australia. From cloud hosting to endpoint protection, we now offer clients a unified experience that blends operational reliability with cyber resilience," Hug said.
"With 5G Networks’ managed IT muscle now part of AUCyber, we’re delivering operational and cyber resilience at scale, secure infrastructure, seamless support, and national reach."
5G Networks first acquired a controlling interest in AUCyber in February 2025 after a takeover bid that began in December 2024. Earlier that month, AUCyber’s CEO, Peter Maloney, resigned from the company following dire financial performance in the months leading up to the end of the year.
“Whilst the four-way merger of AUCloud, PCG Cyber, Venn IT and Arado businesses have recently been integrated, the performance of the newly formed group is unfortunately below expectations,” the company said at the time.
“Revenues in the cyber security, cloud solutions and managed services businesses have all fallen short of expectations, principally due to slower than expected new customer uptake during the period of integration, in addition to recent customer churn.”
The company’s unaudited revenue between July and October was down 29 per cent of AUCyber’s budget for the 2025 financial year.
The company’s share price had fallen from $0.14 at the beginning of 2025 to $0.08 as of 17 October.
