Complete all trails in Royal National Park

I'm trying to walk everything in the Royal National Park other than roads, I've been using alltrails and trailforks to find all trails and bike trails, but there's quite a few tiny traces on strava heatmaps that are either people attempting some heroic bushbashing adventures, or GPS errors. There's a few knots of bike trails around Heathcote that I've walked which are only partially mapped, and I expect I'll find some more.
If anyone knows of any trails not marked on either alltrails or trailforks, I'd greatly appreciate some advice.
Thanks!
