BCEC has been closed since Thursday after Queensland premier Anna Bligh declared the Australian city a "disaster zone".
However, the venue’s event spaces have been unaffected by the floods and BCEC communications manager Gail Sawyer said the centre was expected to return to business by Friday (21 January).
"The impact on the centre of flood waters, which Brisbane is experiencing, is much lower than may have been anticipated," she said.
"Water intrusion was limited to car parking and some service areas and thanks to the wonderful spirit and commitment of the centre’s staff, many of whom worked throughout the weekend to assist with the clean up, we are working towards a gradual return to business by the end of the week and to be fully operational shortly after that."
Sawyer added the BCEC has "heavy bookings" throughout the year and was looking forward to returning to "business as usual".
A total of 18 people have died as a result of the floods, which have affected 86 towns and cities across Queensland.
Meanwhile, the organisers of Asia-Pacific Incentives & Meetings Expo (AIME), which is being held in Melbourne on 15 and 16 February, will conduct a fundraising drive to assist those affected by the flood damage in Queensland.
The Melbourne Convention and Visitors Bureau (MCVB) and Reed Travel Exhibitions (RTE) have announced the joint initiative today.
