Is anywhere in the Brisbane area more than 45 minutes from a cold body of water suitable for swimming in? I don't think there are crocodiles near Brisbane.
In the context of needing to cool down for survival reasons, during a heat wave + power outage + 100% humidity, I suppose it doesn't matter whether the beach you have access to is rocky or not.
I took the original message as being, if you're near the sea, the air around you is cooler so the environment it's self is less harsh.
Though I can guarantee on a hot day, 2.5 million people aren't making their way to beaches or water holes to cool off. And Brisbane is a sweaty place in Summer.
