The AFL has dealt firmly with concerns over the integrity of the last round of the home and away season by introducing a weekend off before the finals.

The final round of the 2016 Toyota AFL premiership season will take place on the weekend of August 26-28, a fortnight before the opening weekend of the finals.

It is the most sweeping change to the structure of the season since national expansion sparked the introduction of Friday night and Sunday games in the 1980s and should ensure that finals-bound clubs no longer select half-strength teams to close out the home and away season.

"The AFL has introduced a bye week before the finals so that those clubs playing in September can have the best possible lead-in and preparation for the most important matches of our season," AFL chief executive Gillon McLachlan said on Thursday.

The 2016 finals series will start on the weekend of September 10-12 and the Grand Final will be held on October 1.

McLachlan admitted there were "risks in disrupting the momentum of the season", but said there were also enormous opportunities, such as waiting until the Monday night of the final round to play a match that might determine the make-up of the finals.

He indicated the AFL would leave the final make-up of round 23 until as late as possible to take advantage of any scheduling opportunities.

McLachlan also flagged playing the opening week of the finals over a four-day period, with perhaps a Thursday night opening match.

Discussions are already underway with broadcasters and other stakeholders as to how to fill the void over the football-free weekend, but there is the possibility of staging several of the major wards, such as the NAB AFL Rising Star, the All Australian and AFLPA MVP Awards over those few days.

The Brownlow Medal will not be moved, however, with McLachlan indicating his strong preference is for it to remain on the Monday before the Grand Final.

The free weekend also paves the way for state leagues and suburban and regional leagues to beef up their excitement around their finals series and perhaps even bring forward their Grand Finals to a weekend when there will be no competition from the AFL.

Finals-bound teams have been grappling with their selections for the last round of the home and away season for as long as there have been finals. But the matter has come to a head in recent years.
