For HD streaming (1080p), 25 Mbps is sufficient for a single stream. For 4K Ultra HD, Netflix recommends 25 Mbps per stream. If you have multiple people streaming simultaneously, we recommend 50/20 Mbps (Go Quick) for 2-3 streams or 100/20 Mbps (Go Mega) for 4+ streams. This ensures buffer-free viewing even during peak hours.

Buffering usually happens for three reasons: (1) Your plan speed is too low for the number of simultaneous activities, (2) Wi-Fi issues between your router and device, or (3) Peak hour congestion on lower-tier plans. If you’re on 25/10 and have multiple devices active, consider upgrading. Also check your router placement – walls and distance significantly impact Wi-Fi performance.

Each 4K stream needs about 25 Mbps. With Go Quick (50/20), you can reliably run 1-2 4K streams. Go Mega (100/20) handles 3-4 4K streams. For households with 5+ TVs all streaming in 4K, consider 250/100 Mbps or higher. Remember, other devices (phones, tablets, smart home) also use bandwidth.

Absolutely. YouTube TV, Kayo, Foxtel Now, and all live streaming services work well on NBN. Live services are more demanding than on-demand because they can’t buffer ahead as effectively. We recommend at least 50/20 Mbps for reliable live streaming, especially if other people in the household are also online.

Yes, significantly. A 5GB movie takes about 30 minutes to download on 25/10, 15 minutes on 50/20, 7 minutes on 100/20, and under 2 minutes on 500/50. If you frequently download content for offline viewing (flights, commutes), faster speeds make a real difference to your preparation time.

The plan speed doesn’t change the maximum quality – that’s set by the streaming service. However, higher speed plans ensure you consistently get the maximum quality. Lower plans might drop to HD or SD during peak hours or when others are online. Higher plans maintain 4K quality reliably.
