A guy on his 30th birthday decided to give 30 presents to complete strangers and to film their reactions...

In his words:
Hello! My name is Lucas and I'm Brazilian. Since I arrived in Australia a lot of beautiful things happened in my life, so on the day I turned 30 I decided to celebrate in a special way, being grateful to the people of Sydney. :)
Thank you so much to all my friends who helped make this happen, without you it would not have been possible. And thank you to everyone who lives in Australia, making this country such a wonderful place.
A big hug, Lucas.
