Picking nine winners is proving a challenge in the 2016 Chemist Warehouse Crows Tipping competition.

The best last round was eight correct, with the weekly prize of a $50 CROWmania voucher going to Geoff Tobin.

The overall leaders are Luke Williams and Nathan Adam, locked on 56 points out of a possible 72 from the opening eight rounds.

It’s not too late to get involved in the competition and chase some prizes.
