I am curious about what this bug is called. It is on my compost bin in sydney, Australia.
Could you please let me know? If I need to remove it or whether it is fine for it to be around the compost bin.
Thank you in advance.

These are the larvae of Black Soldier Flies, Hermetia illucens, and they are frequently found in compost piles where they are beneficial, helping to break down organic substances. According to BugGuide: “Wide ranging in Western Hemisphere, also in Australasia, Africa, Japan, Europe. Commercially distributed for composting” because “larvae compete with house flies in manure, compost piles, etc., and may thus be beneficial. Adults are harmless and not known to carry any human disease.”
