Why are there so many empty shops in Newmarket?

Newmarket's Broadway precinct has in the past been a go to for shoppers. About five years ago it even got a brand new upmarket Westfield mall, but still had a mix of one off boutiques and stores including Karen Walker and Kate Sylvester, on the main strip and surrounding streets. Now there are multiple ghost shops on Broadway, displaying signage of stores that no longer exist and with a heavy sprinkling of "for lease" signs. Mark Knoff Thomas from the Newmarket Business Association spoke to Lisa Owen.
