I proposed an idea to speak at LCA in Auckland, so I travelled internationally to speak. The event asked me to buy a ticket at full price, and I was not paid to speak. The event did not pay for my travel and accommodation. My employer paid all of my travel expenses, and I was working while speaking at the event. It took me 30 days to prepare for my 30 minutes speaking slot, and I had a great time. I'm a man who has been speaking for 40 years. This was a not for profit event. Also, Organisers provided many speakers' perqs; paid accomodation and travel was provided for a small number of speakers who could not otherwise afford to be there.
