Yup, the MTP is on 16 Jan, my son is in P2 though.

Regarding hook turn, it is keeping left to turn right. And yes they do have sign before the Hook turn junction. Go youtube and watch it. It is not that bad, just goto look out for it.

Yes, i declare at the custom. I think it is better to be upfront about it. You can just bring your instant noodle, should be ok. The worst case is just the noodles getting thrown away

Actually just came back from Melbourne. Brought 3-in-1 Milo and milk powder there with no issue. Driving is relatively easy there, just need to do abit on homework on hook turn in the CBD. Outside CBD is the same as Singapore.
