Releasing helium balloons to celebrate a wedding, birthday or memorial could soon become a thing of the past after legislation seeking to ban the practice statewide was introduced to WA Parliament this week.

WA Greens MP Robin Chapple introduced the amendment to the Litter Act 1979 (WA) in parliament on Tuesday.

The "balloon" amendment would make it illegal to "inflate a party balloon outdoors, have an inflated party balloon outdoors, or release or cause an inflated party balloon to be released outdoors".

It will also mean officers will be able to issue on-the-spot fines for offenders.
