For gigs, i definitely recommend petitioning over leaflets. With signing people up to petitions, you not only can use their name + email for the petition, but it allows Unleashed to email them on other issues - i.e. they get all the issues digitally as they would with a leaflet. People are also likely to throw leaflets away when at a gig.
If you're interested petitioning, you can use this petition:
http://www.unleashed.org.au/documents/unleashed-petition-HJ.pdf
For every person going, allow 16 copies of the petition spread over 4 clipboards each, with each person having 4 pens.
I also recommend getting an Unleashed or Animals Australia T-shirt. Not only will others recognize your with an organization, but it will let you feel more confident too.
With your 4 clipboards, just approach groups lined up ready to go inside.
I say something like, "hey guys, interested in signing a petition against animal cruelty?"
99% of people will say yes straight away, and most of the time you won't even be asked about the issue. Once you've secured their emails + names, say thanks and go to the next group. It really is as easy as that!
Also, make sure to get there an hour or so before the doors are meant to open. It will allow you more time to talk with the crowd and get petitions signed, so you don't need to rush.
Good luck with it, and if you have any questions (cos I probably wasn't that clear in my excitement of someone else getting active haha), you can always ask me!
), except to say that if you spot any other great opporutnities, let me know and I'll see what I can do to assist in arrange helpers.
