November is always a funny time around the Sydney Swans headquarters - out of nowhere, players who look neat and tidy and completely respectable for 11 months of the year, begin to look a little unruly.

This November has been no exception, with several players sporting hilarious moustaches all in the name of charity.

Movember is an annual, month-long celebration of the moustache, highlighting men’s health issues, specifically prostate cancer and depression in men.

Mo Bros, supported by their Mo Sistas, start Movember (November 1st) clean shaven and then have the remainder of the month to grow and groom their moustache. During Movember, Mo Bros raise essential funds and awareness for Movember’s men’s health partners - The Prostate Cancer Foundation of Australia and beyondblue - the national depression initiative.
