The modem stats are fine yeah, theres nothing wrong with those.
The issue im having is a drastic difference between download speed (measured in megabits) compared to my sync speed (also measured in megabits for consistency)
I'd expect something like 15mbps off of a 18mbps sync, not the 4mbps im currently getting.
I have performed isolation tests and my SNR looks fine based on the stats.
If its congestion theres nothing I can really do about it until telstra updates their hardware (fat chance on that).
