Route advice

Princes highway (M1) until Heathcote left onto Heathcote Road merge onto M5 motorway then onto M7 till M4 then Penrith.
Or up the Picton Road to the Hume motorway onto the M7 then M4.
Either way there is a climb out of Wollongong.

Thanks William. Just hoping it’s not too steep and winding.

Put the route into a GPS with "fastest selected" - will take you as suggested - up Mt Ousely, Picton Road, Hume Motorway (at Wilton), M7 near Liverpool, then onto the M4 - all too easy.

About 100km - all too easy.

I posted this file earlier in response to a similar question. It lists gradients etc for several routes up from the coast. You may find it useful.
