ABOUT 1000 people who built homes recently in Kellyville, Kellyville Ridge, The Ponds, Stanhope Gardens and Parklea should thank David Kempe.
He was the one who started a Facebook campaign, Residents Against the Rouse Hill Land Charge, that spurred hundreds of protest letters and emails to state and federal MPs and saved residents about $5000 each over five years.
Last week, Minister for Finance Services Andrew Constance announced the state government had reduced the land charge from $246 a quarter to $59 a quarter after a review.
He said the charge had been introduced to help pay for the purchase of land to provide the stormwater drainage services.
It applies to all newly connected properties in the five suburbs.
"I am advised Sydney Water has reduced the charge and has backdated the reduction to the commencement of the land charge on July 1, 2012," Mr Constance said.
Mr Kempe said he was never told about the land charge before buying the land for his new home at Kellyville North and learnt about it from others in the area.
"I then set up my protest site to urge everyone affected by this levy to complain and ask for a review," he said.
"I am delighted by the government's backdown but still feel they shouldn't even charge the reduced rate of $59 per quarter."
He believes this charge should be shared by all residents and developers of the land.
Greenway federal MP Michelle Rowland said she had received "a large amount of correspondence" from affected residents.
"I made representations to the government on their behalf and am glad they have moved to reduce this fee," she said.
