On 26 October 2006, Bayly signed a professional two-year contract with Leeds. Bayly made his full debut in the final game of the 2006–07 Championship season away to Derby County. However, it was a debut to forget as he was shown a straight red card after appearing to attempt to headbutt Craig Fagan, although no actual contact was made. Bayly was released by Leeds early on during the 2008–2009 season despite featuring on a few occasions for Leeds during pre season. During his time in England he also played for the Republic of Ireland U19's.
Bayly joined Sporting Fingal before the start of the 2009 League of Ireland First Division season.

Despite a successful season at Sporting Fingal, Bayly parted company with the club at the end of the season.
Bayly signed for Shamrock Rovers on 15 March 2010. He made his debut as a substitute the next day at Tallaght Stadium. He scored Rovers' equaliser in the Europa League tie against Bnei Yehuda Tel Aviv F.C. in the first European game at Tallaght Stadium. In total, Bayly scored 3 goals in 35 appearances for the Hoops.
In February 2011, Robert signed for Pat Fenlon's Bohemians just in time for the new season.

This came in a 1–0 defeat to Galway United at Dalymount Park. He scored his first goal for the club against Shelbourne on 25 April in an EA Sports Cup tie at Tolka Park.
Bayly left Bohemians in October 2011 after 26 league appearances for the club. His last appearance came against Shamrock Rovers on 5 October in a 1–1 draw.
