His big brother might be a cult hero in NSW but Cameron Skelton wants to make his name elsewhere.

A day after giant Waratahs second-rower Will Skelton scorched all in his path to set up Bernard Foley's 76th minute try against the Brumbies and seal a home grand final for his teammates, Fairfax Media can reveal his 19-year-old brother has joined two-time Super Rugby champions the Chiefs.

At 145kg and 205cm, the younger Skelton was a valued member of the Waratahs' under-20s squad and was set to join the senior squad this coming pre-season to begin the challenging transition to Super Rugby.

But after representing Samoa in the junior world championships in New Zealand last month, Cameron Skelton was offered a package too good to pass up from Dave Rennie and the Chiefs.
