In Brief

A Flinders University study found that the growing popularity of caravans and campers in Australia is increasing the load on regional wastewater treatment systems due to chemicals in toilet systems, especially bronopol, which breaks down into formaldehyde.

A Flinders University study, published in the Journal of Environmental Management, has found that the increasing use of caravans and campers in Australia is placing additional strain on regional wastewater treatment systems. The cause is chemicals used in toilet systems.

A survey of 160 users revealed that 65% regularly use deodorants, cleaning agents, and disinfectants, with 83% following recommended dosages. The most popular products contain bronopol, which CAN break down into formaldehyde and other toxic compounds, disrupting the microorganisms in treatment plants.

During peak tourist seasons, the increased volume of chemically treated wastewater can reduce treatment efficiency and impact the environment.

Caravan toilet chemicals strain regional wastewater systems in Australia

A Flinders University study found that the surge in caravan and camper usage in Australia increases pressure on regional wastewater treatment plants due to chemicals in toilet systems. A survey of 160 caravan users showed that 65% regularly use detergent, deodorizer, and sanitizer products, with bronopol-based ones being most popular; bronopol can break down into formaldehyde and other toxic compounds. During peak holiday periods, higher volumes of chemically treated wastewater may reduce treatment efficiency and affect nearby environments.

The vehicle accommodated up to six people, with two convertible beds and an overcab bed, plus a small kitchen, toilet, and shower.

Major redesign proposed for holiday park on Sunshine Coast

A revised redevelopment plan for the former Golden Beach Holiday Park, closed in February 2026, has been submitted to Sunshine Coast Council. The proposal replaces an earlier single-tower concept with four residential buildings up to 18 meters (six stories) containing 220 two- and three-bedroom apartments. The plan would remove 55 campsites, which the applicant argues represents 2.7% of coastal tourist park supply in the region, with negligible impact. The project includes 20% of apartments (about 36) at below-market rent for 10 years and 25% (about 55) at 25% below market rent for 25 years. Public submissions close on June 9.
