Flying Fijian open-side flanker Sailosi Rabonaqica will have a big role to play in tomorrow afternoon's Pacific Nations Cup showdown against Australia A.

After being named in the starting line-up to replace injured Aca Ratuva, the national 7s rep knows the expectation from the coaching staff for him to lift his performance.

Speaking to Fijivillage, High Performance Unit Manager Peter Murphy said Rabonaqica has big shoes to fill and they are confident he will rise to the occasion on Sunday afternoon.
