Scrambling is making your way over rocks, where you need to use your hands and not just your feet.
Yeah, I got that

I spent 25 years in the mountains of western Canada and climbed/scrambled about 400 hundred mountains. I'm being a bit cheeky quoting Dan John, but scrambling is different things to different people. It's common in mountainous countries to "scramble" up to Ewbank 15, so what constitutes scrambling does vary among people.
Rather than a stiff boot, I would say, although depending on what the OP wants to do, a new shoe may not be required, but approach shoes are designed for exactly this activity.
Regardless, I'm not sure North Head is typical "scrambling" terrain but I guess you could do some "scrambling" around the rocks at low tide. That Sydney sandstone though is friable and breaks easily so some caution might be warranted to check hand and foot holds before committing to them. Alternatively, try some of the local bouldering areas which typically will have some easier short scrambles - although at the grade you want they won't be in the guide, you'll have to be a bit observant and find them yourself.
There is probably some better "scrambling" up in the Blue Mountains, say trying a route up the Ruined Castle or some of the many passes that descend through the escarpment. Classic Australian scrambles would be something like Yullinda Crater, or scrambling up some of the Glasshouse Mountains or possibly even Watsons Crags.
Also a fair bit of scrambling terrain in the Budawangs - The Castle, Byangee Walls, Shrouded Gods, all have what are considered scramble routes and there is certainly plenty of scope for scrambling many of the Budawang peaks.
