Embassies & Consulates
It's important to realise what your embassy can and cannot do for you while abroad. If you have all your money and documents stolen, it might assist with getting a new passport, but a loan for onward travel is almost always out of the question. Generally speaking, they won't be much help if you're in trouble that is remotely your own fault; you are bound by the laws of the country you are visiting.
Nations such as Australia, Canada, New Zealand and the US have embassies and consulates across Central Europe in capitals and major cities. You can find locations using these websites:
New Zealand (www.mfat.govt.nz)
United Kingdom (www.fco.gov.uk)
United States (www.travel.state.gov)
