AWB Limited will shut its remaining 2009-10 wheat pools next Tuesday.
It follows the closure of some pools in Western Australia and South Australia last week.
AWB commodities general manager Mitch Morison said growers intending to deliver to the pool should make arrangements promptly.
Mr Morison said growers could take a pool access contract or transfer their grain to the AWB pool by midnight Tuesday.
AWB has kept its 2009-10 estimated pool returns unchanged for all grades unchanged.
The EPR for Australian Premium White wheat is still $254 a tonne, FOB, for eastern Australia.
