"I had always had an NBN 50 plan because I didn't want the risk of slow internet, but when I moved apartments recently I tried out the NBN 25. I'm 1 person who mostly works from the office, so I just use it for streaming music, TV and occasionally gaming or the odd Zoom call if I'm working from home. It's been totally fine, except for a few occasions when I've had friends staying and the quality of video calls drops out. Definitely not a big enough problem for me to go up to NBN 50, but you should consider your own usage."
