A substantial algal bloom affecting popular beaches in South Australia has raised alarms for holidaymakers during the Easter long weekend. Initially identified on the Fleurieu Peninsula last month, this bloom has since extended to areas including the southern Yorke Peninsula and Kangaroo Island, eliciting concerns regarding both public safety and marine health.
Authorities are urging beach visitors to remain cautious. Richard and Isabelle Alp, who visited Port Elliot, expressed hesitancy about entering the water, with Ms Alp emphasising the need to ensure safety before swimming. The South Australian Department of Primary Industries and Regions (PIRSA) has classified the event as “significant.”
Beachgoers are advised to be vigilant about discoloured water and foam, which are indicators of higher algae concentrations, as noted by Dr David Cunliffe, a principal water quality adviser at SA Health. While symptoms such as itchy eyes and breathing problems can occur, officials have reassured that there are no lasting effects from the algae on human health, although it poses a greater risk to marine ecosystems.
The Environmental Protection Authority (EPA) remains optimistic about ecological recovery, contingent upon the bloom’s duration. EPA principal marine scientist Sam Gaylard stated that recovery is expected, though it depends on rainfall to disperse the algae. In light of this situation, commercial pipi fishers near the Murray Mouth have been temporarily suspended to avoid potential food safety complications.
Experts continue to monitor the situation, providing guidance to minimise risk while acknowledging the need for significant weather changes to promote healing within the affected marine environments. Given the unpredictability of the bloom’s lifespan, visitors are encouraged to stay informed and cautious as conditions evolve.
