Hi,
Anything and everything is an accurate list.
Plus, seconder has small pack with some food, water, head torches, light approach shoes, (sneakers are fine), often light weight warm jackets, (I often use a light water proof jacket).
Long slings, I’d take double ropes if I had them, and a good head for runouts is mandatory. Be conservative. If you pick a climb at your maximum, it will be an epic.
Relax. Enjoy.
It’s a completely different head space to a 5 metre climb on a Perth boulder.
