Your most local ones are all sandstone, so it's worth pointing out that that comes with a few best practice notes to be aware of to protect the rock.
Don't climb wet sandstone because it can be very easily damaged. Going into winter it's more likely that it will be wet and climbing would be bad karma. Some walls dry quick so it isnt a total write off, just do some research and keep in mind conditions.
Extend your top rope rigging and protect edges. Be aware that the rock itself may fail if using placed protection.
Go easy on brushing (soft plastic bristles and light brushing only) and be careful with feet placements, clean shoes to avoid unnecessary wear.
If you're on Facebook the Friends of Pex Hill group has more info on minor crags not in the guide book, conditions etc.
