Appears to be a pretty good price for these headphones for us down under. Amazon sells these for $140. Did some research and found these to be really good ANC headphones at a fraction of the price compared to notable headphones such as the Sony XM4 and the Bose QC35ii/700. Reviews suggest that they have really good ANC, about 80% as good as the XM4s, similar in blocking low noise but not as good in the highs. Rated 60 hours of battery life without ANC and 40 hours with ANC on which is far superior than anything on the market. Reviews on YouTube have been promising. Here's one: https://www.youtube.com/watch?v=ymJQmO77_1Y
An important factor for me when looking for headphones is in the "heatup of the ear" department, the Sony XM4s get pretty warm to my ears after only a short time of listening (20 mins). The Bose QC 35ii do a better job with this and heats up around 30 mins, and the best performing as far as ANC headphones go is the AirPods Max (I've yet to experience ear fatigue). Can only tell how these Q30s will do once I receive them.
Edit: Additional sale at $93.87 (ex GST) tomorrow. I purchased these a few days back for $102 delivered from AliExpress.
