Personally I hate watching low level aerobatics at any air show. I had a scare flying a RAAF Mustang circa 1953 at a Battle of Britain display at Townsville. Got too close to Mt Louisa while barrel-rolling and it put me off low level aeros for good. A couple of years later during a similar display held at Townsville, I watched a RAAF Winjeel doing terribly dangerous low level stall turns in front of the crowd and I was sure someone was going to get hurt. I quickly moved the wife and child back from the crowd towards a safer area. Felt the same uneasy feeling when watching the Avalon Air Show. Must be cautiousness born of old age.
