Melbourne Track Access After Race

Hi, im new here. I'm going to be at the Melbourne Grand Prix on Sunday the 16th and I have park pass tickets. I am planning on sitting at the Inside of turn 2 viewing mound.

I was wondering whether there is any way i could get into the brabham grandstand (during the cooldown lap) to get a closer access to the track for the track walk or whether I'm better of just fanging it from the gate at the general admission section. For reference that adds about 100-150 meters.

Thanks in advance
