Frog Buttress is a cliff on the north-west side of Mount French, in the Moogerah Peaks National Park near the town of Boonah in Queensland, Australia.
A good strategy is to get in a morning climb, and then head off to the Dugandan Pub, about 9 kilometres away in Boonah, for food and beer.
The name "Frog Buttress" refers to some condom packets they found at the top - at the time "French Letters" was a common euphemism.
John Allen and Tobin Sorenson visited in the late 1970s, and made some typically bold ascents.
A striking aspect of Frog is that there are some climbs done there that are so incredibly hard and bold (read: death-falls) that they will only ever get ascents once in a blue moon if they ever do.
