Not confusing really,
Australian Citizens don't need one,
Australian Permanent Residents do.
You can be a permanent resident without being a citizen. Many people that have lived in Australia since the 50s have never bothered to become citizens (English etc).
Perhaps, we were staying close by at the Metro Marlowe too, but they were not open at 6am. I suppose I could have purchased one the previous night but then it would have been cold by the morning.Too bad they don't sell them on the train.
Had a meat pie for breakfast this morning, it was on the train Sydney to Canberra. Not great and I couldn't tell what the brand was. They have switched brands in the last few months and it was certainly not as good as the one I had back in January.
Australians do not currently need a Visa for Argentina or Uruguay however we did have to fill in an entry form for Argentina.
Brazil and Chile you definitely will need a visa so use the official links via smartraveller and apply within the appropriate times to allow processing.
As for Peru and Ecuador, I cannot remember what the requirements were as we were there 10 years ago but smartraveller will have the info.
I arbor no ill feelings for that remark.
I am travelling so didn't want answer as I may not have WiFi til much later in the day. I also only have access to photos from this trip in Egypt.
