Hi all,
I need your advice. I will be taking my first trip overseas shortly and need to get up to speed quickly in terms of the following:
Do you rely on credit cards or other forms of currency (eg travellers cheques, cash in local denominations etc)
Tips on making check in easy
Tips on making luggage secure
In relation to using a computer overseas and charging up a phone -- what advice can you provide re adapters etc. what brand would you recommend and where can this be purchased?
Any other advice using a computer when travelling
What is the best lock for suitcases given different requirements by countries overseas
Any other tips for newbies
I know that some of these issues have probably been discussed previously. So please be patient

. Any and all advice would be greatly appreciated.
Thanks in advance
Just to answer your questions and confirm the other are also right
1. I have a few different methods of accessing money as well as take cash. I usually take a 2 cards each linked to different accounts, plus a comm bank os currency card which in my case is loaded up with US dollars. It acts as a credit card so I use it where ever possible so if the numbers go for a walk I don't end up with major debts. I also take a bit of cash, but I don't store it all in my wallet. I usually divide my cash up and store half in my wallet and the other half with my passport. Whilst ATM's are pretty common in major cities, head away from major cities and you may have a few issues if you don't carry cash.
Try to get used to the local currancy as best you can. Accept that at least one point when you pay with a US $50 note for a $10 debt, you will be given only two $1 notes in change by "accident". Also there is nothing worse than when trying to board a bus your sitting there trying to work out how much $3.50 is using coins which are all the wrong shape size and colour.
Also learn the tipping customs of the place your visiting. There is nothing worse than turning up to a place and being unsure of if it's customary to leave a tip or not. Never ask the bar staff as they will not give an honest answer. Otherwise you risk tipping too much or too little (or not at all), or worse leaving a tip in a place where it's considered rude to do so (I did that once by accident, the guy just smiled, said thanks and said it was not nessacery, didn't make that mistake again).
There are certain places in the world which are renowned for being pickpocket destinations. If you are going to an area where it's likely only carry the bare minimum in your wallet, and better still don't carry your wallet in your back pocket.
2. Check in online if you can, I usually do online check in and then go to the check in counter to get my boarding pass. Status certainly helps a lot in this situation, otherwise just get to the airport as early as possible and give yourself as much time to go through the process.
3. I usually try and carry on only if possible, but in the event that I do need to use checked luggage (for example in 3 week’s time) I have a couple of TSA locks which I place on the bag. Being realistic they will only stop the honest people and the bag accidentally being opened in transit, so with that in mind anything valuable (eg iPad \ Laptop \ Camera \ Money \ expensive coats) goes with me in the cabin.
4. Find out what type of plug they use and go down to dick smith and by a converter for that country (or a universal convertor if you’re going to be doing a lot of travel, I haven't bothered with one as yet as I have a US and a UK type which has seen me through so far). Most appliances can switch between 240v and 110v... Look for something on your power pack which states input voltage 100 - 240V. If it says that then there is no problems using it in any country. I also usually bring a small 4 point powerboard, so I can charge my phone and laptop at the same time.
5. No real advice, I usually find free wifi in coffee shops, and hotels will also sometimes have free wifi. (Hotels are funny, they either give wifi for free, or they charge the most expensive rates for internet access you'll ever find). If you really think it's nessacery you can sometimes buy wireless internet access sims for the local country when you arrive. I've never bothered myself I just keep track of how much I use the internet with global roaming (very sparingly as it's expensive), and use local wifi options where available.
6. TSA locks are best if you plan to travel to the US. Keep in mind that if someone wants to get into your bag (either officially or un-officially) they will either just cut the lock off, or split the zipper or just cut into the bag.
7. Look after your passport, without it you are in a world of hurt. If you lose it at best your travel plans will get disrupted and there are some countries which insist on foreigners carrying their passport (or a photo copy) with them at all times, if you don't have it your likely to get locked up. I usually either carry it on me at all times in my top pocket (but out of sight) or lock it into the room safe. Also keep track of you're money, and make sure if you go to a country that has a departure tax sure you have enough money in cash to pay the departure tax. Don't rely on ATM's at the airport. Very nearly got stuck in the cook islands when we didn't have enough cash to cover departure tax and there was no ATM's available.
Try to remember the names \ locations of where you want to go when you arrive at your destination. Standing on a street corner with a map fully unfolded screams out "I am a tourist, come rob me". This is where a phone with maps and \ or a coffee shop will really come in handy.
Get to the airport as early as possible. There is nothing worse than being stuck in a traffic jam watching precious time tick away. Whilst short domestic flights I am usually willing to cut it a bit closer given there are usually later flights I can catch and it won't cost too much if the airline doesn't just automatically place me on the next available flight, when your in a destination where there is only one flight to Australia per day missing it would be a pain in the rear end if you where to miss it.
If going to a non-english speaking country learn a couple of phrases in the local language. Hello \ Thank You and No will go along way to getting what you want. Keep in mind that certain countries english speakers get the better jobs so don't be surprised when in China you say "nihao" and the person behind the counter says "hello".
Finally enjoy the local food. Eating macca's os is not a cultural experience...
Enjoy your travels and welcome to AFF.
