This time of year, many Australians are kicking back on a beach, soaking up the last lazy holiday moments before normal life resumes. But even an innocent visit to the beach, it seems, is not immune to controversy.

Debate erupted this week over the growing number of beach tents, or “cabanas”, proliferating on Australian beaches. Prime Minister Anthony Albanese weighed in, declaring it was “not on” for beachgoers to erect a cabana, then leave it vacant for hours. Others say cabanas are an eyesore or obstruct the views of lifeguards.

Samuel Cornell, a member of the UNSW Beach Safety Research Group, offers five tips to strike the right balance between personal convenience and public safety when using a cabana.

On the topic of beaches, Nathan Brooks English and Robert Muir urge us not to take seashells home (as many of us do) because they provide important shelter and other benefits for marine wildlife.

“Taking that beautiful snail shell could increase the cost of housing for a hermit crab or the small shrimp that needs it next,” they write. “The beautiful conch shell that calls to you is actually an octopus caravan.”

And if you’ve ever wondered about the colourful, iconic beach shacks that line our shores, Anna Clark unpacks their complex history.

Due to their isolation, these shacks are now sometimes seen as privileged spaces. But as Clark writes, many were once the homes of marginalised people pushed to the fringes of society after colonisation.
