Good event when I went (back in 2012 or 2013, i think it was the first time for the event too), basically a normal format where you have some speakers, they speak about the life of an accountant, the job etc..and then you can network with different firm representatives etc...
Worth going to as there's a lot of chances to speak with representatives of the firm and get an idea if accounting is for you, but also if you're going into commerce/law etc; a good way to warm up to networking events cause they all end up in this kind of format when you're in your later years at uni and go to networking events etc..
