Provisional flying program is now out, although it is somewhat disappointing. Link to Saturday's https://www.airshow.com.au/airshow2019/PUBLIC/program/saturday-program.asp It also looks like the wind will be from the north for most of the weekend, which means aircraft will be taking off from the south. It's probbaly not as good photography-wise. I'd avoid a monopod too, but again, I don't have a 500. With the wind moving around, there may be a need to relocate, so being mobile could be an advantage.
