Gully Platoon are an Australian hip-hop group, composed of Pegz (Tirren Staaf) with Joe New (Joseph Newberry) and Dialectrix (Ryan Leaf).

Tirren Staaf, who is also the CEO of Obese Records, founded the group in 2008.

I've always wanted to have a group for quite a long time now. It's been on the plate for as long as I can remember. I've always wanted to make a group record. I really wanted a different creative process, I wanted to share the writing and really bounce ideas off other people.

He realised his ambitions when Ryan Leaf (originally from the Blue Mountains) came to Melbourne to record the video of his song "Outcast".

After I left Down Under Beats it was always my plan to do a solo endeavour but at the same time [I wanted to] keep my crew-based roots and get on board with a few other like-minded hip hop heads.

Soon after Joseph Newbury also from Down Under Beats, the first Australian hip hop group to win Triple J's Unearthed competition, joined the duo.
