is it an offence to leave a dog in a car

Yes—across Australia it’s an offence to leave a dog in a car if it causes distress, suffering, or risk of harm, and on a warm day that can happen frighteningly fast. Animal welfare laws (think state Prevention of Cruelty to Animals Acts) allow fines in the thousands, and serious cases can lead to prosecution. Police, council rangers or RSPCA inspectors can lawfully enter a vehicle to rescue an animal in danger. “But the window’s cracked!” isn’t a defence; cars turn into ovens.

If you see a dog in distress, call 000 if it’s life‑threatening or contact your state RSPCA for guidance—don’t put yourself at risk. Best practice: take your mate with you, or leave them at home with water and shade.
