Best Technical / Adventerous Hiking Tracks - In & Around Syd

Hello fellow hikers,
I've been hiking around Sydney since I arrived 5 years ago, both me and my girlfriend LOVE technical hikes, ones with climbing, ladders, ropes, scrambles, finding hidden caves, canyones etc.
Can anyone recommend any further technical hikes we would enjoy ideally less than 2 hours from Sydney
Here are some I found technical and enjoyable if you are also looking:
1. Mount Solitary & Ruined Castle - Blue Mountains
2. Devils hole - Blue Mountains
3. Martins Lookout Loop Via Lost World (the shark cave route) - Blue Mountains
4. Hipocrene & Vera Falls Loop - Blue Mountains
5. Mermaid Falls and Tahmoor Canyon Circuit (got a bit lost on this one, not sure if its usually as technical!) - Tahmoor
6. Dadders Cave via Pisgah Rock & Jack Evans Track - Blue Mountains
7. Pigeon House Mountain - Budawang Range
8. Dr. Darks Cave (less technical but was fun trying to find the cave!)
