Police have been forced to take action against three men for breaching the state-wide ban, and a child for committing an act of arson.
On Monday afternoon, a 27-year-old man allegedly lit a small campfire at Fowler Reserve, Wallacia, to boil water for cups of tea.
Police issued him with an on-the-spot $2200 infringement notice.
Later that night, police attend a home in Braidwood Drive, Prestons, following reports a man was burning fence palings in a cylindrical barbecue.
Embers from the fire fell to the ground and ignited palings, causing a second blaze.
The 35-year-old man was also issued with an infringement notice.
On Tuesday morning, a 46-year-old man was arrested after allegedly lighting a fire in a small coal barbecue at a home in Danny Road, Lalor Park.
In the latest incident, a small grass fire broke out in long grass behind Sullivan Street, Worrigee.
When police arrived, a nine-year-old boy, who was with a group of other children, made admissions to lighting the fire with a blowtorch.
The boy was issued a warning.
Anyone who sees suspicious or illegal behaviour is urged to contact police via Crime Stoppers on 1800 333 000.
