In a Liberal dominated area, our best chance is for a Liberal run federal government to be in place for an improvement in infrastructure (including Brooky yes), but also improving traffic congestion, hospitals, schools, and very importantly on the Northern Beaches - traffic congestion (especially considerring our upgrade from low to medium density population control).
If Abbot gets in, that would be $20,000,000 invested all up in Brooky:-
6 mill (provided by State Labor govt in 2008)
4 mill (provided by Local Council - Warringah in 2008)
10 mill (provided by Federal govt in 2010 / 2011)
Add that to the Lighting towers of 1 million in 2006 (I think it was), and that's a cool 21,000,000 in the past 5 years.
We will never be a marginal seat Fluffy (not for probably 2 generations at a minimum.) Potentially your kids could vote Labor, and that's when it might change. Our area is an area with a lot of older, risk adverse residents, who's opinions will never change.
