Europe-bound business travellers can take advantage of the Schengen Agreement, which makes crossing European borders simple -- and in many cases for Australians, visa-free.
Thanks to this agreement, travelling between many countries on continental Europe is actually easier than heading across the Tasman to New Zealand: no borders, no customs checks, no delays, no hassle.
But there are a few catches and caveats that you should be aware of before your trip.
Read on for business traveller-focussed basics about visiting the Schengen area countries, plus links to the official pages to get more information.
Twenty-five European countries are signatories to the Schengen Agreement, which allows free travel and simplified visa arrangements between most Western European countries, with the notable exceptions of the UK and Ireland.
Essentially, once you have legally entered the Schengen area, your travel is domestic within the Schengen area countries: Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden and Switzerland.
Australian passport holders are entitled to a 90-day visa-free stay for business or pleasure in the Schengen area any 180-day period. So going to France for 80 days and then Germany for 20 days immediately afterwards isn't allowed.
For anything more than that, you'll need to take advice from the High Commission or consulate of the country you'll spend most time in.
Only some Schengen countries allow you to undertake paid employment in those countries during that visa-free stay: Belgium, Denmark, Germany, Iceland, Luxembourg, the Netherlands, Norway, Slovenia, Sweden and Switzerland.
But that doesn't always mean you can't do work for your Australian company in Europe visa-free.
So it's always best to take specific advice from the relevant High Commission or consulate to get the precise situation for your circumstances and avoid being turfed out or experiencing difficulties re-entering in the future.
Under Schengen, if you first land in Frankfurt, say, you won't see any difference in the process of getting to your connecting flights for Munich, Madrid, Milan or Marseilles.
It can be a little confusing: at some airports, you don't want to follow the signs for international flights.
You'll also need to make sure you get your passport stamped at your first port of entry to show you're legally in the Schengen area.
And if driving, you often end up in the rather odd situation of asking yourself whether you're in the right country when driving in border areas, because there are no customs points, only signs and the occasional change in road surface to let you know if you've crossed the frontier.
For up to the minute information, and lists of the relevant High Commissions and consulates -- where you should always confirm arrangements before planning your travel -- check the DFAT Smartraveller page on Schengen and the EU Delegation to Australia's Schengen Visa page.
