From the Queensland Fire Department https://www.fire.qld.gov.au/prepare/bushfire/stop-bushfire-arson?

Bushfire arson is a crime, and a major threat to our community.

The devastation which can occur affects whole communities, and recovery is never quick or easy. Records show that up to 50% of all bushfires across Australia are deliberately lit, or start under suspicious circumstances. This comes at a cost of $1.6 billion to the Australian public annually.

Our new Qld Premier Crissafulli has promised "adult time for adult crime". Let's hope that applies to young firebugs and as for adults who put lives at risk in this way, lock them up and throw away the key!
