Australia

• Australia’s currency is also dollars but doesn’t confuse it with the US’s dollars as it is definitely not the same. 1 US dollar is equal to 1.4 Australian dollars. Still, objects like alcohol, permits for attractions, food, and hotel rooms are highly-priced and will burn your pockets more than in the U.S., even with the favourable exchange rate.
• You might be a sturdy and capable swimmer, or you’re tempted by the crystal-clear waters and be tempted to dive in straight away. Australia has a tendency to not to post numerous cautionary signs, but it does make a great deal about the red and yellow flags at the Australian beaches. Thanks to robust riptides, beachgoers—predominantly travellers, who are not familiar to robust currents—are advised to swim in-between the flags for their wellbeing. Some beaches, like Sydney's Tamarama, are frequently shut for swimming.
• The money-saving tip for Australia is not hiring a cab or taxi for going anywhere in and around the city. Australia offers one of the best public transportation systems in the world. The Australian public transport system is way too inexpensive and easy to navigate as compared to the taxis. Recurrent (and tremendously tidy) buses will take you to all of Sydney's lovely beaches, and wherever you wish to be.
• While in Australia, don’t expect a waiter or waitress to come to your table to take your order. You’ll only find servers at high-end eateries, but most fundamental establishments believe in self-service. Classically, you find yourself a seat, glance over the menu, go to a counter with either a person or computer, and place your order. Post this, you'll be provided with a token; a server will bring you your order as soon as it's ready. Naperies, water, utensils, and condiments will naturally be located on the self-serve stations.
• You’re not required to tip at regular eating establishments or casual dining places. However, you will still be anticipated to tip at fine dining restaurants. Since the wages in Australia are high, it is unnecessary to tip.
• If you’re willing to devote too much time out in the sun during your stay in Australia, you'll probably get suffer from heatstroke or sun poisoning. All this because, Australia is situated nearby to Antarctica's "ozone hole," that means more and higher levels of Ultra Violet radiation reach your skin. It is advised to cover up, bound your presence in the sun, drink plenty of liquid, and get some high-SPF sunscreen.
• You should not underestimate the jetlag. The immense time variance from India is not that much, but if you’re travelling from the USA, you should give yourself at least a day to your body to adjust. That way you'll be able to make the most of your time in Australia. Your body clock will be totally out of sorts, so don't try to stretch your meals or sleep timetable around what time it is in your native country. You should go for short walks on your first day of arrival and remain close to your hotel so that you can take a nap and eat as required. It doesn’t matter how much alive or tired you feel, you must fall asleep at a usual (Australian) time and then try and make it completely through the subsequent day.

France

France or Paris is frequently mentioned to as “The City of Light” (or “La Ville Lumière”) or “The City of Love”, is one of the most widespread and sought-after tourist destinations in the world.

• The French people show admiration to each other when it comes to sound levels. In many instances, the people you’ll hear in or bars or cafés at night, talking at the loudest note, will only be English speaking travellers. You should watch out your levels of noise, predominantly in silent villages and towns once the sun goes down, where you’ll want to dodge an annoyed Frenchmen asking you to shut your mouth.
• The French people don’t really prefer heavy breakfast and it tastes much sweet in nature like Croissants, pastries and brioche with coffee or hot chocolate. It’s occasional to find many places, even in big cities, that offer more than this. If you’re able to find one, it’s not typically any more than an egg and a piece of bacon for travellers. Just like the Frenchmen, and it is suggested to go big at lunch and even bigger at dinner.
• There is numerous number of fast-food selections available across France and service almost during the day, conventionally these may not be the best option. Chances are that you might not even find them in smaller towns and villages. Just in case, if you want to dine in an eatery, you should plan your day as lunch usually starts at 12 PM at noon and will go until 2 pm. Dinner starts off at 7 pm. Frenchmen prefer to eat around 7.30 pm at the earliest.
• Do not assume that while strolling and crossing the road, the cars will automatically stop at a pedestrian crossing. If you want to get to the other side of the road and if no one stops, you might have to signal that you actually want to crossover.
• In America or even here in India, everything can be done online. However, while most of the businesses might be online in today’s time, in France, most preparations are still done over the telephone and it may take longer than expected to get back to you if you try to connect by electronic means. This is applicable for everything – reservations, conferences, anything and everything. 
• In case you’re visiting your friend’s or relative for the first time in France, never show up empty-handed. Gifts are exchanged commonly between the French people, and not just on special times. The gifts are exchanged as a small token of friendship and kindness.

Italy

Let is clear the air for you. Italy offers more than just Pizza and Pasta.

• Refrain from wearing clothes with bare shoulders or shorts while visiting Italian churches or cathedrals. Female carry around a stole or scarf to cover the bare shoulders while wearing sleeveless tops. In most of the places, counting the Vatican as well, will not permit people wearing shorts. Hence, it is recommended to plan your attire according to the place you’re going to.
• You should not board a train before authenticating your ticket because the tickets for the local trains don’t have a date or time prescribed on it. This is purely so that a person is able to use whenever he/she wants.
• Before entering a coffee shop and ordering your favourite “Latte”, make sure you know latte actually translates to in Italy. Latte refers to milk in Italy. Hence, do not order a latte if you wish to gulp down coffee. This is one of the common mistakes that travellers do while in Italy.
• Always ask for bottled water if you’re feeling thirsty because there’s no such notion of tap water in eateries or restaurants in Italy because the locals always favour drinking bottled water.
• We know that your credit card is your favourite companion while travelling abroad but don’t rely entirely on credit cards as some of the stores might only accept payment in local currency.
• Obeying to your table conducts would help you load during your Italy trip! Don’t just pick your pizza slice and start biting into it if you wish to avoid the fuming stares of the fellow diners. As an alternative, use a knife and fork to relish this Italian delicacy to the fullest!
