She also praised her husband John, who was dressed in a suit, rather than in his traditional dress Hawaiian shirt, for his "understated love, support and pride in our achievements together".
"He is so tolerant and clever and on any given day you can never be sure what he will come up with next. With him, life is never boring."
Mrs Chadwick spoke about her success in central government and some of her hopes for the future.
"I will be focused on building a team of skilled and committed individuals to develop a broader and deeper sense of community involvement to make our dreams come true. We all agree that vision, drive and sustainable growth are the key to making that happen. Let's recreate ourselves, let's define a new attitude that expresses pride and a sense of place and purpose, let's make this city buzz with excitement and expectation. That's where I'm heading - why don't you join me?"
Mrs Chadwick then took over the meeting from Mr Williams, swearing in her new deputy mayor Dave Donaldson and the remaining 11 district councillors, including the newly elected Peter Bentley, Rob Kent and Tania Tapsell. The new council then got on with business with the first major agenda item being the council's Annual Report.
