I was invited to speak at a conference or 1000 people or so in Sydney. This was a local event. The event gave me a free ticket, and I was paid 500 USD to speak. The event did not pay for my travel and accommodation. I was working while speaking at the event. It took me 1 day to prepare for my 15 minutes speaking slot, and I had a great time. I'm a woman who has been speaking for 10 years. This was a not for profit event.
