While I agree with the comments re fencing. Heavy mesh fencing is far from ideal, chainwire is better, But only when the coating has gone 'off'. Shiny mesh is terrible. Many years ago North Arm bike speedway had a national event and they went crazy with paint to tart the place up,, the painted the wire all silver and it was bloody terrible. I believe they painted it black afterwards.
These days you can buy black chainwire
Similar when I built a 6 foot high tubular fence at my car yard. All galv, reject Hills Hoist beams. Could not see in,, painted it all black and the vision was ok. And it kept most of the thieves out. Though in the stretch of road I was in the pricks still robbed me regualarly. And my fence was the most secure of the lot!
BUT, like so many things that piss people off about modern motorsport is liability insurance. No catch fences=no insurance= no motorsport. And it will never get better.
I went to 2019? dog and pony show [akaClipsal] in the parklands,, free, would never pay and left about 3 hours later,, could not see jack.
And I believe Albert Pk is even worse.
This it seems does not matter in the US, primarily speedways where the cars get out way too often,, drag racing much the same. Aussie speedways are about 100% better
Even watching Goodwood today there are decent fences,,about 4 foot high and components would get past them very easily. These days it tends to scare me though watching some old GP crashes in Europe in the early 90s big turn 1 crashes and wheels going everywhere,, inc out into the crowd. Now that was scarey!!
