In it, the buff 30-year-old channels Tom in his infamous Risky Business dance scene, wearing only his underwear, a shirt and a pair of pink sock for The McGrath Foundtion.

He captioned the clip: Challenge accepted Tom Cruise! Deadset think I tore a hammy though... 'Risky Business' this is (see what I did there)!"

The bulding manager also added: " Now there's a reason I'm dressed like a pork chop and doing my best rendition of Tom Cruise in Risky Business and that's to raise much needed funds for the McGrath Foundation!"

The foundation, which was started by cricketer Glenn McGrath's wife Jane who sadly passed away from breast cancer in 2008, aims to provide home care nurses for those battling the illness.
