She was one of three teenagers who died on October 12, 2002, when the car they were in hit a power pole on Bargo River Road.

For many shire residents the anniversary of this crash is a timely reminder of the lives lost on our roads.

While the council has carried out routine maintenance and implemented road safety programs to stop the carnage, Nathan said it was not enough.

''As far as I'm concerned people are still dying so not enough has been done,'' he said.

''We need more money and more driver awareness schemes so young drivers know how easy it is for things to go wrong, especially on the poor roads we drive on.''

Cr Judy Hannan agreed there was always more that could be done to improve driver safety on Wollondilly roads.

''Since this accident we've done a lot of work and now have a traffic road safety officer employed by the council,'' she said.

''We recently won an award for our learner driver Log Book Run and had a great response from our Sculpture by the Road [roadsafety-themed] exhibition.''

Nathan, who was only 17 when Erin died aged 16, said they had a typical brother-sister relationship.

''That's the hardest thing, knowing that we spent those last few years fighting so much like brothers and sisters do,'' he said.

''And now I'm a bit older I don't have that many happy memories.''

''I look at other brothers and sisters our age and I think, yeah, I want that too, but it's too late. She was the only sister I had.''

''Nathan said his sister was very outgoing and had a lot of friends.

When he spoke to the Advertiser last week tears filled his eyes as he spoke about the night Erin died.

''I was riding my pushbike past the shops at Buxton when the lights flickered on and off,'' he said.

''Then the power shut off completely and when I got home Mum and Dad were in a panic.
