Melbourne 30/7

I’m GA for Laufeys concert tomorrow but the girl I’m going with has work during the day. Would I be able to line up and her meet me after work before we enter or would people get upset over it? I’m really upset because my tickets last year were the very back row so I wanted to get as close as I can but don’t know how it will work with my friend not being there lining up the whole time. Any help is appreciated 🫶
