Get a grip.
The OP image was Adealdie, Australia and the March 2013 picture could be southern hemisphere too. Skin cancer rates in Australia and New Zealand (probably South Africa too) are 2-4 times times higher than US, Canada and UK (depending on the source) as a result of ozone depleation and outdoor lifestyle factors. As a result many people do cover up on the beach including in garments like shown in the March 2013 image which are made of a fabric is designed to block ultra violet rays but be acceptably comfortable in the water. The amount of skin coverage in the OP image is unsuprising on beaches or anywhere outdooors in Australia, although the style of clothing might be uncommon on the beach.

Showing these images is a pretty responsible action by the WTS - even if they also feed into the body modesty ideas they promote.
