The first time I went travelling alone, I was extremely unprepared. But I’d still consider that a helpful experience, for now I know exactly what to avoid, and I can spread my wisdom too.
First and foremost, if you are travelling alone, try keeping the luggage to a minimum. It certainly does not help if you are carrying a huge, big suitcase with you. It will be a good idea for you to invest in a sturdy backpack which can carry all your necessary luggage for an extended journey.
Secondly, do not pack too many clothes. It will be a smarter idea for you to carry clothes that can be mixed-and-matched to create new outfits on a regular basis. Carry clothes that suit the climate too- during summer, you will have to carry enough cottons and shorts. In winters, it might be better for you to carry multiple layers, sturdy boots and one thick jacket that will keep you warm throughout the journey.
Besides this, you should also remember to pack the essentials- some sunscreen, bug repellent, pyjamas, sunglasses, toiletries, basic make-up, etc. You can find many handy lists on the internet that will give you checklists too. Just remember that even if you do forget something basic, you will be able to buy it in Australia.
