from 2018 -- information on Power SANFL Salary Cap and Leadership Player. (below is just an extract -- need to read it all LOL)
The SA Football Commission concluded the annual review of the license conditions and list regulations pertaining to the Adelaide and Port Adelaide Football Club participation in the SANFL competition and has approved the following as players eligible for the AFL clubs supplementary lists:
Any South Australian player who is attaining the age of 19 or older and who is not on the Senior List of a SANFL Club (which is a list of 40 players).
One Leadership Player who has attained the age of twenty six (26) years prior to or during the calendar year in which he is first included on the supplementary list who has been on any AFL list in the season immediately prior.
A maximum of four players from interstate that have attained the age of 18 on January 1st in the year in which they are first included on the AFL club supplementary list (turning 19) but who have not attained the age of 21 on January 1st , each of which can be listed for a maximum of two seasons
AFL approved Next Generation Academy (NGA) and Father Son players can be temporarily permitted during their 18th and 19th years (the years in which they are eligible for drafting with concessions) if nominated by the AFL club they are aligned to. It should be noted that this is subject to the player electing and agreeing to being nominated by AFC and PAFC for temporary permit.
In the 18th year, such a player can be permitted for a period of four games, but will not be eligible for a permit if they have already played League Football at their SANFL club. The SANFL Club will receive a fee in the sum of $2,500.
In the 19th year, a nominated NGA and Father Son player would be available for selection at AFC or PAFC only. At the conclusion of their 19th year SANFL club will have the right to list the player on their senior list. The SANFL Club will receive a fee, in addition to any fee received in the players 18th year, in the sum of $5,000.
Also, a player payment cap will be introduced for the AFC and PAFC in line with the other SANFL clubs, consisting of:
Match payments at a maximum of $400 per League match.
An upfront/base payment maximum (per individual) of $4,000.
Total upfront/base payments (collective) of not more than $20,000 .
In addition, the Leadership Player can only be paid a maximum upfront/ base payment of $20,000 and match payments of $500 per match. If the player was drafted from a SANFL Club prior to his AFL listing, there will also be a transfer fee payable to the SANFL Club in the sum of $25,000, as is the case if the player were to play for any other SANFL Club.
The AFC and PAFC contracted supplementary list will include:
A maximum Contracted Supplementary List of 10 players (including NGA and father son players in their 19th year, such players in their 18th year would be excluded).
A contracted supplementary list player is protected and cannot transfer without consent of AFC or PAFC. Only supplementary list players can be paid a base or upfront payment. Contract period is limited to 12 months (or one season).
Any player otherwise eligible for the supplementary list can be registered to play on permit from their community club with AFC or PAFC. There is no limit on the number of permitted players.
