Dean Mumm



Returning to Australia in 2015 following a stint with English Premiership side, the Exeter Chiefs, Dean Mumm made a welcome return as one of the oldest members of the NSW Waratahs leadership team.


2016 saw the veteran lock become one of three Tahs to earn their double centuries, with 100 NSW and Super Rugby games, together with Dave Dennis and Rob Horne. The year also saw him jump to the top of leaderboard for the Waratahs’ highest capped second rower in the Club’s history.  


Proving he still has what it takes, Mumm crossed for two tries in 2016, one a thrilling runaway try for NSW in the Tahs’ round 12 victory over the Blues and the other for the Wallabies against Argentina at Twickenham. Adding a further 13 Test caps to his name, 2016 also saw Mumm secure his 50th cap for Australia.

A versatile player in the pack, Mumm has firmly established himself as a regular starter ever since his NSW debut back in 2007. In 2016 he added a further 15 NSW caps to his name, playing an average of 75 minutes per match. 

Signing on for a further season for the Tahs, Mumm’s experience on both the second and back row will once again be a key facet for the team in 2017 as they look to continue develop a host of new talent as a legacy for the coming years.  


2015 was a whirlwind year for the lock who was named as the 84th Wallabies Captain against Uruguay during the Rugby World Cup, just four months after returning to Australian rugby and moments before becoming a first-time Dad.

Born in Auckland, New Zealand, Dean relocated to Sydney as a toddler and played his junior Rugby for Beecroft and The King’s School. He captained the King’s first XV in 2001 and 2002, winning the GPS title in 2002. He also captained GPS firsts, NSW Schools and Australian Schoolboys that year.

The grandson of former All Black Bill Mumm, Dean comes from a truly Rugby family. His father John is a former Australian Rugby Union Board member and elder brother Greg a former coaching coordinator at the Waratahs and previous coach at Sydney University, Northern Suburbs and the Fijian national team.
