Cheap Flights to Sidney from HK$4,425

Depending on where you're coming from, your flight to Sidney could be a piece of cake or it could drag on forever. We've put together some useful travel tips that will help you start your next unforgettable escape on a positive note. What to pack in your hand luggage:

• The secret to having a stress-free flight experience is to pack in advance. First up, the essentials: passport, boarding pass, credit cards and daily medications. Next, bring on board items that'll help keep you entertained, like your laptop or a good book. You'll also want to bring your chargers, a quality neck pillow and a pair of earplugs. And of course, don't forget to squeeze in toiletries like a toothbrush, lip balm and a fresh set of clothes.

Do not pack the following items in your hand luggage:

• Pack all your full-sized bottles of shampoo and hair gel in your checked baggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) won't be allowed on. Sharp or pointed objects, like your beloved pocket knife, and dangerous goods which are flammable or explosive, such as aerosol cans, flares and poisons, are also not allowed.

What to wear on a flight:

• Your main aim is to be as comfortable as you can. Choose slip-on footwear, dress in loose, natural-fibre clothing and don't forget to bring a sweater in case it gets chilly in the cabin.
• Most of us have heard about deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity. To reduce your risk on board, stay hydrated, consider wearing compression tights or socks and keep your feet and legs moving.

The trick is to be prepared before you arrive at security. That way, you'll be hopping onto that plane to Sidney in a flash. Follow these helpful tips and get your trip off to a terrific start:

• Have your ID and travel documents someplace easily accessible. They're the first items you'll be asked to show at security.
• The X-ray machine comes next. Empty your pockets and remove anything metal that is likely to set off the alarm. This includes items like headphones or earphones, as well as your coat or jacket. They'll all need to go on the X-ray conveyor belt.
• Your electronic gadgets like phones and laptops will also have to go through the machine to be scanned. Don't worry, you'll be back online before you know it.
• Remove liquids and gels from your carry-on luggage. They usually need to be sent through the X-ray separately. Each item should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-lock bag.
• Choosing your footwear wisely can save you several valuable minutes. Boots and heavy shoes are often required to be removed and separately scanned. Slip-on sneakers are usually not.
• Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, put them in your checked suitcase. They won't be allowed in the cabin.
