[3] The next few seasons saw Offereins plagued by injuries until June 2009 when he set a new personal best for the 400m of 45.69s, a World Championships B qualifier, which earned him the final position on the Australian 4 × 400 m relay team for Berlin 2009.

Running a sensational third leg during the heat (44.78s) Offereins forced his way into the team for the final where the Australian team of John Steffensen, Ben Offereins, Tristan Thomas, and Sean Wroe, won the bronze medal for Australia.

[4] In 2010 Offereins started his season by winning the Australia Cup[5] held in Canberra in a new PB of 45.32 sec, he then broke his PB again at the Sydney Track Classic[6] running 44.86sec[7] and becoming only the eighth Australian to break the 45.00 sec barrier and the seventh fastest Australian of all time.

He continued his form, winning the IAAF Melbourne Track Classic[8] in 45.73sec, and then the Australian National Championships[9] in 45.17 sec.

This gained him automatic selection for the individual 400m and the 4x400 relay at the 2010 Commonwealth Games in Delhi, India.
