All proceeds from the Bandcamp release will be donated to Palestine Australia Relief and Action (PARA) para.org.au
As noted by @tombruzzo@aussie.zone in the comments Bandcamp Fridays (where Bandcamp waives their revenue share and pass the funds directly to artists & labels) starts at 5pm AEST Friday Oct 4 and goes for 24 hours is on. If someone knows exactly when it ends I can update this post.
Updated post again because of ambiguity (also I couldn’t find more details online).
