Is there any genuine growth left in the Australian B2B fixed market?

The market will expand at a 1.6% CAGR to reach $7.501 billion by FY30, a slight improvement over previous cycles. Growth is concentrated in network services, which will outperform the broader market with a 3.0% annual growth rate.

Which customer segments should we prioritize for investment?

The enterprise segment (200+ employees) is the primary growth engine, projected to reach $5.057 billion by FY30 at a 2.0% CAGR. SMB growth will remain constrained at 0.8% due to that segment's heavy reliance on declining legacy voice products.

How quickly are legacy services being phased out?

Legacy voice revenues are collapsing at an 8.0% CAGR as copper decommissioning continues. By FY30, the transition to modern infrastructure will be nearly complete, with IP voice accounting for 81% of all business voice revenue.

What is the outlook for traditional data and connectivity products?

The Data & Internet category is stagnant with a 0.7% CAGR as gains in Ethernet and Internet are neutralized by a -6.0% annual decline in IP-VPN revenues. Operators must pivot to managed network services to find meaningful margin expansion.
