A resident has collected debris littered along the Busselton Jetty following the recent fireworks and raised concerns about the environmental impacts to marine life.
The debris included fireworks casings, packaging and electrical wiring, among other items were fishing lines and rubbish.
One piece of a firework was collected in August 2019, months after the event had taken place, another freezer bag contained rubbish from the morning after the recent fireworks.
Resident Lesley Perry questioned how long the debris had been there.
"The debris I picked up in 2019 had not broken down, it could have come from fireworks in any of the previous years," she said.
"The other bag was collected from the cruise ship platform to the second part of the skeleton jetty near the first shelter.
"Perhaps it's time we thought about more environmentally sound entertainment such as a laser light show so we do not cause harm to the environment and marine life."
City of Busselton mayor Grant Henley said if the impact associated with fireworks was proven to be detrimental to the environment the city might reconsider future use.
"However, in this instance we are not talking about a vast quantity of waste and a significant amount of the content of the freezer bag would appear to be unrelated litter," he said.
Mr Henley said the use of laser lights had not been explored in depth, but previous enquiries indicated it would be cost prohibited.
