Aussiebum briefs and square cuts are perfectly suitable for any sports pool or beach so long as you go for medium to dark colours, the whites and ice blues are intentionally transparent when wet (buy some anyway). In the Uk if you buy from Aussibum directly you get charged customs and the Post Office charges a handling fee so buy a number of swimsuits, underwear and shorts in one go to avoid the same PO handling charge on each item. Have a look at Aussiebum jockstraps if you need to make up the size of a package.

Going to a remote beach gives you more space and freedom to wear something briefer than you would at the town beach full of board shorts. If you should meet someone at that remote beach the chances are that they too are after a bit of space and freedom to do as they choose too. As they approach don't hurriedly dress pretending you weren't naked or wearing something skimpy, they've already seen you and can guess. Position yourself and perhaps by using a towel or tee shirt cover the bits so they can't actually see anything as they pass. If they appear friendly and choose to stop and chat or to adopt a patch adjacent to you let the towel or tee shirt drop and let them know what there getting into, you were there first.
