Yes, most important question to answer would be, "where are the budawangs?". I think the National Park names themselves can lead to some confusion.
Some markers:
- Mount Budawang - Which is wayyyy down south, about 30-40km away from where most people refer to "the budawangs"
- the Budawang Range - Stretching roughly 60km from Mt Budawang in the south through to Sassafras in the north
- Budawang NP - Contains Mt Budawang and the southern half of the Budawang Range. Doesn't really cover the area which most people refer to "the budawangs".
- Morton NP - Adjoins Budawangs NP, and contains the area which most people refer to "the budawangs" at its southern extent.
- "the Budawangs" - The area with all those interesting cliff formations in which people enjoy bushwalking
Below a little image to illustrate.
- Top red area in roughly where most people refer to "the budawangs"
- Bottom read area is roughly Budawang NP
- Blue marker is Mt Budawang
- Red line is the Budawang Range
- the budawangs
Maybe the best resouce would be the classic sketch map "The Northern Budwang Range an the upper Clyde River Valley" by George Elliott -
https://nla.gov.au/nla.obj-232773360/view. I would think that really covers what most people call "the Budawangs", and the key is sort of in the title. Maybe "the Budwangs" is really just "The Northern Budawang Range"
