AussieBum Waltzing Matilda Worldwide underwear and swimwear billboards...

The skies of L.A. are certainly heating up for Summer, thanks in no small part to the latest beefcake-packed billboards from Australian swimwear, underwear and leisurewear brand, AussieBum.

These hunky outdoor ads from Down Under have been absent from the skyline of West Hollywood for far too long, so it's nice to see their return with some fine bodied specimens modeling their briefs and trunks.

Their new slogan embraces Australia's infamous bush ballad, 'Waltzing Matilda', and we're sure many you wouldn't mind bumping into these buff guys if you were wandering the outback or traveling the globe.

The red hot underwear billboard was first spied along Santa Monica Boulevard in West Hollywood on December 31, 2014, whilst the cool blue swimwear billboard was snapped in the same Boys Town location on April 30, 2015.

If you're a fan of the underwear and swimwear brand, be sure to also check out these AussieBum billboards from years past.

Enjoy this early Mother's Day present, and let's hope these won't be the last billboards AussieBum has to offer this year.
