I was invited to speak at Web Directions South in Sydney, so I travelled internationally to speak. The event gave me a free ticket, and I was paid 1000 USD to speak. My travel and accommodation was fully covered by the event. My employer did not pay my travel expenses, and I took unpaid time off to speak. It took me 45 hours to prepare for my 45 minutes speaking slot, and I had a great time. I'm a person who has been speaking for 2 years. This was a for profit event. Also, Also gave a free conference ticket for my spouse. Super fast at paying. Wonderful speaker experience!
