Murray Rose Pool in Double Bay is closed after it has been declared unsuitable for swimming as part of widespread water quality warnings across Sydney following this week’s heavy rainfall.
The harbourside swimming enclosure is currently listed as a “red flag” location by Beachwatch NSW due to likely contamination. The nearby Rose Bay Beach is also affected by the pollution warning.
According to Beachwatch NSW’s online monitoring system, the contamination primarily impacts Sydney Harbour swimming spots, with both Murray Rose Pool and Rose Bay Beach showing elevated pollution risks.
UNSW research fellow Dr. Jasmin Martino explains that rainfall is a major driver of ocean pollution, as stormwater runoff can introduce contaminants including E. coli into waterways. Harbour swimming spots are particularly susceptible due to limited tidal flushing compared to ocean beaches.
The timing of these pollution warnings coincides with peak bull shark season in Sydney Harbour, which typically occurs during January and February. Dr. Martino notes that bull sharks are most active when water temperatures are warm and after high rainfall or floods.
Beachwatch NSW continues to monitor water quality and advises checking their website before swimming. The general recommendation is to avoid harbour swimming for at least three days following heavy rainfall.
