You need bandwidth over a short distance in an area that has a lot of 5GHz congestion and the idea of paying for a microwave license, especially in a major capital city scares you?
24GHz is a frequency band you can use, subject to some ACMA guidelines, to establish a 1-2Gbps link between two sites up to 5km apart.
This is definately a solution worth pursuing with a number of vendors providing solutions like SAF, Ubiquiti and Mimosa
