https://www.thecrag.com/en/climbing/australia/booroomba-rocksBooroomba is one of my favourite places, but it has access challenges and indeed can be difficult to find. They’ve had major fires which has affected routes and bolts. It can be murderously hot and humid. Facebook has a Canberra Climbing site, I’d recommend you join, people will be very helpful if they can.
Water, between 2 of us. We carried 2 litres each and retreated at midday as we’d used it all on more than one occasion.
I’ve had a few days at Nowra, this is short pitched sandstone.
For the Gramps, this is the link

I’ve been to the Bluies many times and never managed to climb because of the rain!
I’m sure you know already how expensive things are and check the t’s and c’s for car rental. Most in Australia have a charge by the kilometre and in Australia there are a lot of those.
