FEWER than 1000 tickets remain for Saturday's twilight preliminary final between Greater Western Sydney and the Western Bulldogs at Spotless Stadium after a high-paced morning of sales on Monday.

More than 8000 Bulldogs members snapped up tickets during the exclusive sales period on Monday, while about 6200 Giants members secured their seats, mostly in a two-hour rush from 9am.

Despite fears some of the Bulldogs' 40,000 members or the 16,000-strong Giants membership base would be locked out of the 24,000 capacity venue, there were about 4600 tickets made available to the general public after 1pm.

About 950 tickets remain unsold as of 9:00am Tuesday morning, primarily in standing room, and the League hopes the historic clash will sell out by the middle of the week. 

AFL general manager, club and AFL operations Travis Auld said the League was pleased all Giants and Bulldogs members who had wanted to buy tickets were able to access them in the exclusive member sale period.

Unsold tickets remain available at face value – ranging from $65 to $179 for adults.
