We always travel light and essential only and going to Sydney should mean proximity to shops if extra supplies/items are needed.

Definitely second the below, don’t take bubs entire wardrobe. Our first trip away I packed way too much clothing. And his bath… So unnecessary.

If you are organising a hire car, don’t take a car seat with you, they can supply one. Some companies even supply prams or you can find a place that you can rent one from. Don’t take too many clothes as you can wash them in the sink and let them dry. I would suggest only taking a couple of pairs of shoes, i always take far too many and end up wearing my thongs or sneakers most of the time. Remember to take travel size shampoo, tooth paste, maybe a disposable tooth brush etc. If you are staying close to supermarket, i wouldn’t take too many nappies, wipes etc as you can easily get these when you get there. Just take what you think you might need for a couple of days and buy the rest when you get there. Have a fantastic holiday.
