OK it takes more than that idea, based on winds first. NE wind Bondi. Facing south NE handles well several board hires, not a classic beach over crowded with a zoo of tourists, with no idea of surf etiquette.
Maroubra catches different swell, and has a north end for shelter from the NE. Lots of different peaks less crowds but a strong local crew. I'll post this and give you a surf report.
A 4 to 6 ft SE swell, winds variable, I'd suggest Maroubra if they are reasonable surfers........ tell them about not surfing in the flagged areas, btw parking is easier at The bra.
They should have been there yesterday

If you consider the northern beaches Long Reef could be the go! Or on the Manly Stretch you can adapt to different wind conditions at the appropriate end board hire there.
I've taken up troll hunting just for fun, instead of a rifle I'll just use a pun! 冲浪爷爷
