Jayzus Jono, you've gone and put Terrys Ave near the end of the hilly bit.
Smales, Inverness and Terrys. hmmm... looks like a pretty hard ride.
Give Dorset Rd the arse though, go up Boronia Rd a bit more and turn right down Forest Rd... much less chance of being cleaned up.
If you get a chance, go take a look at Roma Pde (the lower part) in Upwey. Supposed to be the steepest road in the area... looks like a vertical line from the mad mile. They had to make it out of rough concrete so the cars can get up it. Oh, and it's a dead end at the bottom.
