Power & Adaptors

  • Voltage: 120V
  • Frequency: 60Hz
  • Power Plug Types: Type A and Type B

Travellers will need a USA Type A/B travel adaptor. Appliances which operate on 240/220V like Australia, check whether devices such as hair dryers or straighteners support dual voltage otherwise they will not work. Best to bring a Universal International adapter.

Visa Requirements

Most passport holders generally require an Electronic System for Travel Authorization (ESTA) to enter the United States for tourism or business visits of up to 90 days under the Visa Waiver Program.

Always check the latest government travel advice before travelling.

Before You Travel

  • Apply for your ESTA well before departure.
  • Your passport should remain valid for the duration of your stay (six months validity is recommended).
  • You may be asked to provide proof of onward travel and accommodation.
  • Customs may check your social media activity.
  • Complete any required customs and immigration declarations.
  • Comprehensive travel insurance is strongly recommended due to the high cost of medical care in the United States.

 

Cultural Etiquette

Americans are generally friendly, informal and welcoming.

Local Tips

  • Friendly conversation with shop staff and service workers is common.
  • Tipping is expected in restaurants, bars, taxis and for many hospitality services. Tips typically are 15-20%.
  • Respect queues and personal space.
  • Smoking and vaping restrictions vary by state and city.
  • Ask permission before photographing people, particularly children.
  • Follow local laws carefully, as regulations can differ between states.

 

Transport Tips

The USA is designed for road travel, although many major cities also have excellent public transport.

  • Car Hire: Ideal for road trips through California, Florida, Texas, the Southwest and national parks.
  • Domestic Flights: The quickest way to travel between distant cities.
  • Metro & Subway: Available in cities including New York, Washington DC, Chicago, Boston and San Francisco.
  • Rideshare: Uber and Lyft operate in most major cities.
  • Amtrak: A comfortable way to travel between many cities and scenic regions.

Travel Tips:

1.      Distances between destinations can be much greater than they appear on a map, so plan driving times carefully.

2.     Best to bring your physical Driver’s License, because Digital Licenses may not be acceptable in all states.
