Police collected the firearm and are now investigating who might have left it.
Gel blasters are illegal weapons in most states and territories in Australia or require a permit to be used, except for Queensland where owners do not require a licence.
In NSW, people cannot acquire permits for gel blasters or their ammunition.
NSW Police said on its website: “No genuine reason exists to possess or use a gel blaster in NSW.”
