FRIDAY night's preliminary final blockbuster between Richmond and Collingwood is a sellout, with Saturday's clash between West Coast and Melbourne also fully subscribed.

AFL members' tickets went on sale at 9am on Tuesday and sold out within 30 minutes, leaving many fans without a seat.

Ticketek Australia tweeted there would be "no further tickets released for sale".

On Monday, Richmond and Collingwood club members snapped up 40,000 tickets in about two hours, resulting in the scheduled general public sale to be cancelled.

MCC visitor tickets and reserved seats have also sold out, with remaining full and restricted members to fight over the remaining 13,000 walkup seats.

Gates to the MCC reserve open at 5pm on Friday, with fans expected to be lining up at the MCG long before that.

Already on eBay, sellers are advertising tickets for the Tigers-Pies preliminary final clash at highly inflated prices.

One scalper is selling two tickets on level 1 for $1575, around five times the normal price.

Under a recent Victorian state government crackdown, it is illegal to sell finals tickets at a premium of more than 10 per cent of the original value.

The MCC is predicting a crowd of 97,000 fans to pack out the ground to witness the Tigers and Magpies do battle in September for the first time in 38 years.

The AFL record for a Friday night crowd is 98,002 at the Geelong-Collingwood preliminary final at the MCG in 2007.

It's the same story at Optus Stadium for the second preliminary final between West Coast and Melbourne, with the 60,000-seat venue also sold out.

A total of 59,585 fans attended the first ever AFL final at Optus Stadium between the Eagles and Pies a fortnight ago, with a new record expected on Saturday afternoon.

All flights from Melbourne to Perth on Friday have sold out, with very limited options available on the morning of the game.
