Stefaans Brümmer, South Africais an experienced investigative journalist.

He co-founded the amaBhungane Centre for Investigative Journalism, South Africa's only fully-fledged investigative non-profit, in 2010.

At amaBhungane (isiZulu for 'the dung beetles'), Brümmer divides his time between the demands of media bureaucracy (which he detests), coaching members of the amaBhungane team, and his first love, digging for dung.

He has co-authored exposés including the turn-of-the-century Arms Deal scandal, Oilgate, the Selebi affair and Chancellor House. Of late, his passion has been the #GuptaLeaks, a 2017 leak of a huge trove implicating South Africa's president, ministers and an immigrant family.

A politics and journalism graduate, he cut his reporting teeth at The Argus in Cape Town during the tumultuous early 1990s; then joined the uppity weekly Mail & Guardian as democracy dawned in April 1994.
