Bull began performing in and around Sydney in the early 2000s. He signed to Island Records, a part of Universal Music Australia, in 2007. He supported Joss Stone on her Australian tour later that year. Bull release a 7" single of "We're Too Young", followed by "Small Town Girl," was released in August 2008. It was also released as a part of a four-track self-titled EP; which featured three original songs and a cover of "A Man Needs a Maid" by Neil Young.

Bull's debut album, We're Too Young, was released in August 2009. A music video was made for "Young Man," the third single from the album. Bull toured extensively in support of the album throughout the rest of 2008 and 2009, notably joining Tim Finn's national tour as an opening act, performing solo. He also opened for a MySpace secret show in Sydney featuring Duffy that same year.

In May 2009, Bull toured in support of Lisa Mitchell's Australian tour, prior to the July release of her debut album Wonder, fomenting Bull and Mitchell's friendship, which would lead to their collaboration on Bull's song "Dog" the following year.

In 2010, Bull began writing new material after relocating to Surry Hills. He was inspired to record a duet with Lisa Mitchell after performing a cover of Madonna's "Like a Prayer" with her and Lanie Lane at Sydney's Enmore Theatre during Mitchell's headlining performance at the venue. The resulting song was "Dog". Its popularity resulted in being featured in the Triple J Hottest 100 of 2010, charting at number 68.

"Dog," along with five other new songs, featured on Bull's Phantom Pains EP. He played piano, guitar and drums on the EP. He was also joined by former Red Riders guitarist Adrian Deutsh and Deep Sea Arcade/Tim Finn drummer Carlos Adura, as well as Deep Sea Arcade bassist Nick Weaver. Along with Mitchell, the EP also featured special guests Little Red and Hungry Kids of Hungary as Bull's backing band on the songs "Nothing to Lose" and "Last Waltz," respectively. A music video was made for the EP's title track, in which a man cuts off his thumb in order to get workplace compensation. The EP artwork was painted by Bull, and features a depiction of his left hand with a severed thumb.

In October 2010, Bull joined Clare Bowditch's national tour for a series of stops as her opening act, joining Augie March frontman Glenn Richards. For these dates, he was joined by Slow Down Honey guitarist Alex Bennison. Bull and Bennison did a small headlining tour in the following weeks, and later joined Canadian singer-songwriter Dan Mangan on the New South Wales leg of his national tour in January 2011. He also headed out on a headlining tour of the east coast with Melbourne singer Owl Eyes, titled the Bulls Eye Tour, in February.
