Where "Bombora" Comes From
"Bombora" comes from the Aboriginal language of the Sydney basin, most likely Dharug, possibly referring originally to a specific stretch of water off Dobroyd Head in Sydney Harbour.
The term generalised over time to describe any submerged reef or rock shelf that creates a distinctive, often dangerous, wave formation offshore — a feature prized by experienced big-wave surfers and feared by unwary boaties.
"The surfers paddled out to the bombora for the bigger swell."
How Aussies Actually Use It
"Bombora," often shortened to "bommie," is standard vocabulary among surfers and fishers describing a specific kind of offshore wave break.
It carries a note of respect and caution, since bomboras can be hazardous to boats that don't know they're there, even in otherwise calm conditions.
