I will also say that some of the big events that I worked at ANZ Stadium included:
* Asian Cup Final 2015 as well as a few of the round robin games
* State of Origin NSW V QLD in 2014 & 2015
* NRL games
* Super Rugby matches
* AFL fixtures
* Bledisloe Cup Aus v NZ
* Bon Jovi concert
If you guys are keen, they advertise the jobs through SEEK and are pretty much looking for anyone (including uni students). You will need a couple of things 1) Food Handlers Certificate and 2) RSA certificate.
I worked in a lot of jobs before but working at ANZ was one of the best experiences I ever had. (better than the labour jobs I did, working in an office in government etc) I also spoke to a lot of university students during that time as well that were working there casually. Also ANZ treat you not like a number, they have their annual christmas parties they hold in November-December, give discounted meals and occasionally you will get free drinks.
