How live bidding works at the AFL draft

HOW LIVE AFL DRAFT BIDS WILL WORK

* Melbourne picks Sydney academy player Callum Mills with selection No.3

* Sydney decide to match the offer (this only applies to northern academy or father-son nominations)

* Each draft pick has a points value - in this case 2234 - and Sydney are given a discount of 20 per cent. That brings the pick value down to 1787

* Sydney need to give up their draft picks at 33, 36, 37 and 44 to have enough points to match Melbourne's bid and take Mills

* Melbourne have the next pick in the draft at No.4
