Concept Overview — Why It Matters in Australia
The NBN (National Broadband Network) connects over 12 million premises across Australia. Your plan’s speed tier directly affects how fast you can stream, download and work from home. Choosing the right speed means balancing cost and performance.
As of 2025, most major providers (Telstra, Optus, TPG, Aussie Broadband, etc.) offer four main residential tiers — NBN 25, NBN 50, NBN 100 and NBN 250. Some areas with fibre upgrades can access NBN 1000 (Gigabit), but it’s not yet universal.
