The milestone sale went to a family who has already been living at Huntlee for almost a year.

Troy and Loblei Motbey and their son Chad moved into their home in September.

Baby Chloe was born in January, making her one of the first Huntlee-born residents.

Formerly of Singleton, the Motbeys were drawn to Huntlee for its family-friendly environment and access to the Hunter Expressway.

They like living there so much they decided to buy another block and build a bigger home, while keeping their current home as an investment property.

“It was always going to be a stepping stone… but the amount of growth here has been amazing,” Mr Motbey said.

Huntlee project director Stephen Thompson said he was delighted that the 500th sale is to one of the town’s current families.

“It shows what a thriving community Huntlee already is,” he said.

“As a fully master-planned town, our intention for Huntlee was always to offer solutions to cater for every stage of life our residents are at.

“It's great that the Motbeys have enjoyed their time here at Huntlee and decided they want to own a larger piece of it.”

The 500^th land sale coincides with Huntlee’s 100th family moving into their completed home.

Civil works for stage one of the town centre are almost complete, ready for the first operators to commence construction. The town centre will include a Coles supermarket, medical centre, childcare facility and a pub.

“In all, the Hunter's first new town in more than 50 years is progressing well. It's great to see our community thriving with so much more to come,” Mr Thompson said.
