We've had a good year of public sex acts here at Asylum Australia, and today there's another contender for best of 2009. Leaving car antics to the beginners, here we discover a couple taking to a clock tower high above Sydney's Broadway shopping centre.

If you're unfamiliar with the area, this is very high above the street. And it is a very busy street. Quite the combo to deliver a mixture of highly public rumpy pumpy with little chance of being identified, plus a definite thrill factor where the girl is showing some serious trust not to fall to her death.

Well, we thought we'd seen it all earlier in the year. Now we don't know what to say. Should we expect a better spot of public woo hoo before the year is done? Is this the cream of the crop, so to speak? Or was one of the earlier couples doing a better job?
