Its just recognizing the physical limits that are imposed by the existing satellites. This is a reasonable response.
What is less reasonable is the very large delay between recognizing the problem, and taking action to mitigate it.
A cynic might suggest that as the current communication minister said that there was sufficient capacity in the existing satellites (before the election) that the delay in addressing the problem was political...
Hopefully when the new satellites are launched these problems will be a thing of the past, as the NBN, acting as a proper National Carrier, will continually monitor the requirements and add new satellites as required.
