The AFL's complex live bidding system will again be in use at Friday night's draft in Sydney.

This is the second time the clubs will use the system to make and match bids on academy and father-son prospects during the draft, after the AFL established its new points-based system for the 2015 NAB AFL Draft in Adelaide.

This will see the draft order change throughout the night as clubs matching bids will move up to the selection where the bid was placed.

To 'pay' for highly rated players, clubs can use multiple picks to accrue enough points, which will also affect the draft order on the night.

The selections that clubs start the night with will not be the same as those they will have made at the end of the draft.

GIANTS Academy midfielder Will Setterfield is tipped to be the first player to attract a bid, while bids could also come for his fellow Academy pair Harry Perryman and Harrison Macreadie.

HOW LIVE DRAFT BIDS WILL WORK (Example)

• Melbourne picks GIANTS academy player Will Setterfield with selection No.3

• The GIANTS 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 the GIANTS are given a discount of 20 per cent. That brings the pick value down to 1787

• The GIANTS need to give up their draft picks at 33, 36, 37 and 44 to have enough points to match Melbourne's bid and take Setterfield.

• Melbourne has the next pick in the draft at No.4

Clubs will sit in partitioned sections of a separate room to where selections are announced to the crowd and players, with the clubs  making their choices via a technological program developed by the League and Champion Data. 

Senior coaches will reveal their team's selections to the crowd for first-round picks. If a club is not involved in the first round, its senior coach will read out its first selection.
