The BCCI on Thursday wrote to Cricket Australia seeking relaxation in hard quarantine protocol of Brisbane for the fourth Test to go ahead, reminding the host board that the visitors are done with the strict isolation that was agreed upon at the beginning of the tour.

It is learnt that a top BCCI executive has written to CA head Earl Eddings citing to him the Memorandum of Understanding signed by the two boards on the modalities of the tour which never had any specification on two hard quarantines in separate cities.
