A permit is not required from Council if you are only burning dry vegetation for domestic purposes such as yard maintenance. A responsible person does need to tend to the fire at all times. You should also consider your neighbours so any smoke does not cause them a nuisance. A minimum of 24 hours notice is required.
Commercial operators, however will not be granted consent to burn waste that's a by product of there business, for example tree surgeons. You are encouraged to recycle, mulch or dispose of your waste to a licenced waste facility.
A permit to burn is always required from these agencies during the bushfire danger period
ie 1st September to 31st March
People who burn anything by open fire, or an incinerator have a legal responsibility to prevent or minimise air pollution.
