not sure why people feel it's going to be a great to BNE when we have two international airports a lot closer with good highway connections, Wellcamp is a very slow long and boring 140km away, perfect for giving Toowoomba and surrounds a proper regional airport.
The answer is in your comment. BNE (which is over capacity) will now have good domestic airports to its SOUTH, NORTH and WEST. Which other Australian city has access to this level of infrastructure? 4 jet service airports within 2 to 3 hours of each other?
I know people in the south of BNE who much prefer to use OOL rather than BNE. In the future when MCY gets bigger, people to the north will have that option. Now people in the West will be able to use Wellcamp (YBWW). If you live in the west, is a much quicker trip, especially when the by pass goes in and the new tunnel is finished, around 1 to 1.25 hours max.
I have taken longer to get to SYD and MEL in traffic from their CBD's..
