You don't need to remind the residents of Cranbourne East that they inhabit one of the nation's fastest growing suburbs.

The place has been one big construction site for years, one of the engine rooms powering Melbourne's population boom along with other suburbs on the city's fringe.

And people keep wanting to move in – just last year Cranbourne East added the equivalent of a small Victorian town to an already heaving corner of south-east Melbourne.

"Basically, if there's a bit of green land it's starting to be built on or already has been built on," said resident Emma Gainsford, 39, a mother of three young children.
