Queensland Premier Peter Beattie said on Tuesday the final segment of the stadium renovation would be completed by early next year, adding 5,000 seats and boosting the ground's capacity to 42,000.
Queensland Cricket said it would lobby for more International games to be played at the Gabba when redevelopment of the Brisbane stadium is completed.
"In light of this decision, Queensland Cricket looks forward to building a persuasive case for more international cricket to be played at the venue in the future," Queensland Cricket chairman Damien Mullins said on Tuesday.
"The new capacity of 42,000 puts the Gabba on a par with the Sydney Cricket Ground and ensures that Brisbane more than holds its own with the established major cricket venues in Sydney and Melbourne.
"Cricket Australia controls the scheduling of international matches but we believe there will be strong arguments in the Gabba's favour to increase the number of international games played in Brisbane."
Mullins said he hoped the Gabba would see more international action, with the stadium due to be completed in time for South Africa's scheduled tour of Australia in 2005-06. The ground usually hosts one Test and two Limited Overs Internationals each year.
