It's hard to say how important it is. For one thing, each country has its own laws relative to courtesy flags
. You'd want to check this, 'cause it's from a long time ago, but Indonesia
used to require that you fy their flag both higher than your own country's ensign, and the courtesy flag had to be larger than your ensign, as well, on pain of a large fine. But each country's laws may vary, and be updated.
There is an outfit up north, either in northern Qld or NT (I don't remember) that makes lots of courtesy flags
, and relatively cheaply as well. Maybe Googling on "flag makers in Australia" would get you there.
We have always just flown the courtesy flag, on the assumption that since we are a guest in the foreign country, we should show them that respect. I used to make them from spinnaker
cloth "off-cuts", the scraps that were given to me by a sailmaker
. Most flags
are not too difficult to replicate, either with hand stitching or sewn on a machine. It's difficult to find them for sale
many places, and others charge over $100 per flag to buy it there! They don't usually have to last very long, so don't have to be made too strong or use expensive fabric
How important is it? I'm not sure someone else can decide that for you. We think it's important to try and be a good ambassador for our nation. How you feel about that issue may help decide about the courtesy flag issue, and other cross cultural issues you may encounter.
