SYDNEY (Reuters) - Former Wallabies lock Dan Vickerman was remembered as a "colossal" man who gave selflessly to rugby at an emotional public memorial in Sydney on Wednesday.

The South African-born forward died at home at the age of 37 last month, triggering mourning across the rugby world and shining the spotlight on the mental health of retired athletes.
