Lily was an engaging, funny and relaxed speaker. She came early and was well prepared. The speech content was perfect for the event and audience. Lily ran the game 'numbers' brilliantly and it was a really great addition to our event allowing people to see her in action in our very own ABS numbers game. She was also very generous with her time staying behind to sign autographs and for people to get their photo taken with her. Australian Bureau of Statistics
