The AFL could force GWS to shift a home final against Sydney to ANZ Stadium to accommodate extra fans if the fixture eventuates.
A playoffs match between the two would be expected to draw at least 60,000 spectators, well exceeding the 24,000 who can fit in the Giants' normal home ground, Spotless Stadium.
The AFL have therefore confirmed to News Corp Australia they would consider moving the match across the road to the former Olympic venue if it were available.
ANZ Stadium has not hosted an AFL match in 2016 after the Swans opted to sever ties with the ground before the beginning of the season.
The two Sydney sides are currently second and third on the ladder with four rounds to play, with the Giants therefore due to host the Swans if positions stay as they are.
The NRL have priority at the ground, however only Canterbury appear to have any chance of hosting a game at the venue throughout the first three weeks of the finals series.
A clash is therefore unlikely.
The Giants would like the match to be played at Spotless Stadium where they have a 5-1 record this year but understand the AFL's interest in discussing a move.
